RENESAS ZMOD4510 Evaluation Kit
Description
The ZMOD4510 Evaluation Kit (EVK) is designed for evaluating Renesas’ ZMOD4510
Gas Sensor Module for Total Outdoor Air Quality (OAQ 1st Generation) or
selective ozone measurements (OAQ 2nd Generation). The device is ideal for
monitoring and reporting Outdoor Air Quality according to the standard of the
US Environmental Protection Agency (EPA). The Air Quality Index (AQI) output
is based on a combination of outdoor gases present, including nitrogen oxides
(NOx) and/or ozone (O3)a. Renesas’ Gas Sensor Evaluation Software allows
Windows®-based operating systems to communicate with the ZMOD4510 EVK via a
USB connection on the user’s computer, which functions as a master. The
software and additional related documentation is available on the Renesas
website.
The EVK’s Communication Board (HiCom) handles the interface between the user’s
computer and the ZMOD4510 module mounted on the ZMOD4510 Sensor Board (i.e.,
daughter board). Note: Only one Communication Board with one Sensor Board can
be connected to the computer at a time. The ZMOD4510 Evaluation Kit uses an
FTDI controller on the Communication Board to handle the USB protocol,
translate communications, and synchronize communications with the I2C
interface. The Sensor Board includes a decoupling capacitor.
The Communication Board has devices mounted on both sides. The components on
the top side generate a stable supply voltage. A potentiometer can be used to
adjust the internal supply voltage in the typical range from 1.7V to 3.6V.
Alternatively, the user’s external supply voltage can be used. The intensity
of the adjacent LED is proportional to the supply voltage.

ZMOD4510 Evaluation Kit
1. Setup
Initial Startup
To set up and operate the ZMOD4510 Evaluation Kit (EVK) with the ZMOD4510, see the ZMOD4510 EVK Quick Start Guide document included in the kit.
Required or Recommended User Equipment
By default, the internal supply voltage for powering the Sensor Board is
generated from the USB voltage supplied by the user’s computer via the USB
cable. If there is a need for currents higher than the defined USB standard
(usually 500mA at 5V), an external voltage supply source can be used instead
of the internally generated voltage supply provided on the Communication
Board.
The external supply only powers the sensor modules, and not the communication
board itself. The supply must meet the following requirements:
- Voltage – 1.7V to 3.6V
- Current must meet the user’s specifications – The minimum is 30mA for electronics with additional current needed for each gas sensor module of approximately 11mA (in OAQ 1st Gen Operation Mode with a 1.8V voltage supply).
User Computer Requirements
Computer Requirements
A Windows-based computer is required for interfacing with the EVK and
configuring the ZMOD4510. The user must have administrative rights on the
computer to download and install the Gas Sensor Evaluation Software.
The computer must meet the following requirements:
- 1GB RAM
- Hard drive with at least 1GB free space
- 1 USB port (preferred USB 2.x)
- Windows Vista®/Windows 7®/Windows 8®/Windows 10®
- Internet access for initial download of the drivers and software
Important: Before installing and activating the software, assemble and connect the hardware for the kit to the user’s computer according to steps 1 through 3 in section “EVK Hardware Connections and Initial Power-up.”
Software Installation and Setup
Before using the Gas Sensor Evaluation Software, the USB drivers for the FTDI
device must be installed. Download the drivers and corresponding installation
guides from the FTDI website. The drivers will not affect the operation of any
other USB peripherals. The kit does not need to be connected during
installation of the drivers.
Complete the following procedure to download and install the Gas Evaluation
Software with the kit connected:
- Download the ZMOD4510 Gas Sensor Evaluation Software zip file from the Renesas website.
- Create a folder on the user’s computer for the software (e.g., C:\Program Files (x86)\Renesas Software). Extract the contents of the downloaded zip file into this folder.
- Double-click on the extracted batch file GasSensorEvaluation.bat to start the software. There is no need for an installation of this software for user convenience. Figure 1 shows the initial display after execution.
Select the measurement mode to run the sensor in “OAQ 1st Gen” for Total Outdoor Air Quality or “OAQ 2nd Gen: Selective Ozone with Ultra-Low Power” for ozone measurements.
EVK Hardware Connections and Initial Power-up
To set up the EVK hardware before using the software, complete the following procedure:
- Refer to Figure 2, Figure 3, and Table 1 to determine the correct jumper settings for the ZMOD4510 Communication Board depending on whether an external supply or the internal voltage supply on the board is used.
- If the internal voltage supply is used, ensure that the jumper is across the pins labeled “int” on the K2 connector.
- If using an external supply, ensure that the jumper is across the pins labeled “ext” on the K2 connector. In this case, without connecting the external supply to the Communication Board, verify that the external voltage supply setting does not exceed the voltage supply specifications — a minimum of 1.7V or a maximum of 3.6V — as per the ZMOD4510 Datasheet. With the external supply off, connect the external voltage to the 2-pin “+ – V ext” header adjacent to the K2 jumper with the orientation indicated in Figure 3. Note: If this option is used, adjustments of the external voltage are not possible on either the Communication Board or the Sensor Board for adjusting an external voltage supply.
- Install the ZMOD4510 Sensor Board on the 14-pin connector on the Communication Board, taking care to ensure the proper orientation of the Sensor Board as shown on page 1.
- Insert the micro-USB cable into the X1 connector on the Communication Board and connect it to a free USB port on the user’s computer. If the external voltage supply has been selected, turn on the external supply and verify that the D3 LED adjacent to the potentiometer is on (see Figure 2). Note: The intensity of the green D3 LED is proportional to the supply voltage.
- Activate the software as described in section 1.4.
- If the internal voltage is used, the Gas Sensor Evaluation Software activates the internal voltage after the sensor has been started. Use the metal potentiometer to the left of the K2 connector to adjust the VDD supply voltage in the typical range from 1.7V to 3.6V as measured across the V_TGT and GND pins available on the K3 connector as shown in Figure 3. Its initial adjustment on delivery provides a voltage of VDD ≈ 2.0V. Once a measurement has been started by the software, the green D3 LED adjacent to K2 will light with an intensity proportional to the voltage supply that was set using the potentiometer.
- Verify that the red D1 LED is on, which indicates that the kit is properly connected and powered (see Figure 2).
The Communication Board provides the additional K1, K3, and Modul1 connectors for the following optional uses as described in Table 1. To make use of any of these options, contact Renesas for further instructions (see contact information on last page).
- Extra measurement options (e.g., current consumption to determine the power requirements of the ZMOD4510)
- Connections for additional sensors via I2C interface

Usage Guide
When the Gas Sensor Evaluation software is started, the initial window is displayed as shown in Figure 4. The initial display in all operation modes consists of three blocks:
- Measurement Control
- Signal Analysis
- Plot Visualization
Measurement Control Block and Output File
The “Measurement” area of the display allows users to start the ZMOD4510’s gas measurements. When the “start sensor” button is clicked, the button name changes to “stop sensor” and the measurement starts running continuously. The sampling rates are displayed in Table 2.
Sample Rates
Operation Mode | Sample Rate [Seconds] |
---|---|
OAQ 2nd Gen: Selective Ozone and Ultra-Low Power | 1.998 |
OAQ 1st Gen | 60 |
The results will be saved in a comma separated file (CSV), which is user-
selected via the file and path selection dialog when the sensor is started.
This CSV file contains multiple sensor parameter (e.g., the sensor tracking
number, the production lot number, calibration parameters etc.) In addition,
all raw sensor signals (resistances) for each measurement step and temperature
are recorded (e.g., MOX_200C_8, which is the resistance of the MOx sensor at
200°C). All these additional information and parameters are usually used for
debugging and validation only. The focus should be drawn to the relevant
parameters such as the algorithm results: The air quality index (AQI) and/or
ozone concentration.
A comment (e.g., “Start test”) can be added to the data entry by adding a text
string to the “Add comment to next measurement” field and then clicking the
“OK” button. If a measurement is already in progress, the comment will be
added to the next measurement. The comments will be displayed in the plot and
will be saved in the CSV result file. This facilitates tracking the user’s
experimental investigations. Below this entry field, a small window with a log
field shows all events logged.
Signal Analysis Block and Options
Signal Analysis Block User Options
Display Section | Button/Action | Description |
---|
Data Source
| | This option allows the loading of previously recorded csv files into the EVK software when having the same csv file column structure. This feature can also be used to compare results of ZMOD4510 EVK software with ZMOD4510 firmware csv files. For this usage, it is not necessary to connect the ZMOD4510 Evaluation Kit hardware.
Display
|
| The “clear memory” button will delete all current data from the plots (memory). The data in the measurement file will remain.
If measurements are acquired simultaneously for multiple ZMOD4510 gas sensors, the measurement results file can contain data from different sensors. In the “Sensor” drop-down menu, the user can choose a sensor to display by selecting the unique sensor identification number.
The drop-down menu adjacent to the “show” button provides options for selecting the time period for showing the recent history or the complete data. Click the “show” button to apply new settings to the plots.
Algorithm Parameter
|
| For OAQ 2nd Generation a temperature and humidity compensation are recommended. This is enabled by default in case a temperature and humidity sensor is connected. The Renesas HS3001 sensor is added from Daughter Board revision R 1-2 onwards; alternatively, a sensor can be connected via the Modul1 connector.
If a temperature or humidity sensor are found, the settings for the parameters can be set manually in this field.
The Visualization field allows to change the plot between “EPA AQI”, “Fast AQI”, and the actual Ozone concentration in parts-per-billion (ppb). The original EPA standard averages concentrations over time (concentration depended up to 8 hours) and quick changes may not be seen (e.g., during demonstrations and testing). The “FAST AQI” allows the same AQI calculations based on a 1-minute average.
Display Section | Button/Action | Description |

Algorithm Result
|
| For OAQ 1st Gen operation (Total Outdoor Air Quality):
This method of operation has a sample rate of 1 minute resulting in 1 hour for the initialization measurements. This hour splits into two parts: While the first 20 minutes are without any algorithmic results, the remaining 40 minutes show a first estimation of the “Air Quality Index” (AQI). Results will be accurate after 1 hour of operation.
For OAQ 2nd Gen operation (Selective Ozone with Ultra-Low Power):
The first 901 measurements will be taken for sensor stabilization during OAQ. During this time, the “Algorithm Result” section will indicate the completion progress and will continually show the sensor resistance R_MOx. Results will be accurate after 30 minutes of operation.
Note that this does not cover the full stabilization of the sensor module. After the stabilization measurements, the AQI is shown in six categories:
0 to 50 Good Air Quality
51 to 100 Moderate Air Quality
101 to 150 Unhealthy Air Quality for Sensitive Groups 151 to 200 Unhealthy Air Quality
201 to 300 Very Unhealthy Air Quality
300 Hazardous Air Quality
Plot Visualization Block
The lower half of the display provides a visualization of the data. This shows the plots for the options selected in the algorithm parameter field, as well as the raw sensor output signal (in Ω). For additional information, including application notes, white papers and blogs, visit the ZMOD4510 product page.
Error Codes
Due to some interference between the FTDI, Windows operation system, and the
computer’s USB driver, a startup problem may occur on some systems if the EVK
is started on a USB 3 port. Renesas recommends using a USB 2.x port for the
initial startup of the EVK. Other common error messages are explained in Table
5.
Note: Always make sure the downloaded zip-file has been unzipped before
starting the executable GasSensorEvaluation.bat file.
