Sensor

Product Information

The Wireless Ambient Humidity & Temperature Sensor
WS433M12F-ATH is a product that consists of two components: the Wireless Sensor Transmitter 433Mhz and the Compact Ambient Humidity & Temperature Sensor DULP Module. The sensor is factory calibrated and outputs both humidity and temperature values. The humidity measuring range is 0-100%RH with an accuracy of +/- 2.0%,and the temperature measuring range is -40 to +85 oC with an accuracy of +/- 0.2 oC. The sensor has a resolution of 0.1% for humidity and 0.1 oC for temperature. It also has a 20um alloy sintered filter and uses an M12-male connector for electrical connection. The wireless transmitter has a data speed of up to 50kbps and a transmission distance of up to 1000m line- of-sight (LOS) with an internal antenna. It uses one AA 1.5-3.6VDC battery that can provide up to 10 years of operation depending on configuration. The frequency band used is ISM 433Mhz, Sub-GHz technology from Texas Instrument, USA. The product complies with international standards such as ETSI EN 300 220, EN 303 204 (Europe), FCC CFR47 Part15 (US), ARIB STD-T108 (Japan), and Vietnam Type Approval Certification.

Product Usage Instructions

1. Connect the Wireless Sensor Transmitter 433Mhz and the Compact Ambient Humidity & Temperature Sensor DULP Module using an M12-male connector.
2. Insert one AA 1.5-3.6VDC battery into the wireless transmitter.
3. Mount the sensor using the included L-type bracket and M4 screws or double-sided 3M tape.
4. Ensure that the operating temperature of the product does not exceed -40oC to +60oC (with AA L91 Energizer).
5. The product is now ready to use. When the sensor sampling time interval is reached, for example 2 minutes, the node will wake up and switch ON the power supply to supply the energy to external sensor to start the measurement. The sensor will take a certain time to finish the measurement. Once reading the sensor value, the raw data is X, it can be scaled to any engineering value using the formula: Y = aX + b where X is the raw value and Y is the calculated value. The Y value will be compared with Lo and Hi threshold to determine if there is an error or if the sensor module needs to be exchanged.

Introduction

Wireless Ambient Humidity & Temperature Sensor is a combination of wireless sensor transmitter WS433-M12F and sensor ATH, it utilises Digital capacitance humidity sensor to deliver high accuracy and stable measurement. The wireless portion is Sub-GHz technology from Texas Instruments allows long range transmission at ultra-low power consumption. It will connect 2-way wirelessly to the wireless co-ordinator WS433-CL to send data and receiving the configuration. It can be configured the operation parameters like data sending interval, health check cycle…remotely from Globiots platform or via ModbusRTU software (thru the WS433-CL). Its default data rate is 50 kbps, can be switched to 625 bps to increase the communication range. It can last up to 10 years with a single AA battery. There are a lot of applications as environment monitoring for office, warehouse, data center, hospital, agriculture…

Operation principle

Process of measurement
When the sensor sampling time interval is reached, for example 2 minutes, the node will wake up and switch ON the power supply to supply the energy to external sensor to start the measurement. Depends on the type and characteristic of external sensor, the sensor will take a certain time to finish the measurement.
For example, the measurement time is 200mS, after this time, the node will read the value of sensor using I2C, node will switch OFF power supply to external sensor to save energy.
Once reading the sensor value, the raw data is X, it can be scaled to any engineering value by the following formula:
Y = aX + b

Where:

• X: the raw value, reading from output of sensor before calibrated/validated;
• Y: the calculated value, a desired output value of sensor, after calibrated/validated;
• a: constant (default value is 1)
• b: constant (default value is 0)

By default a= 1 and b=0 ==> Y=X
The Y value will be compared with Lo and Hi threshold.

Wireless sensor configuration with coordinator

You can configure the wireless sensor with the co-ordinator by following the steps in the link below:
http://www.daviteq.com/en/manuals/books/long-range-wireless-co-ordinator- ws433-cl/page/user-guidefor-long-range-wireless-co-ordinator-ws433-cl

Installation

Mounting bracket installation

Locate the place where the wireless sensor is mounted, from that locate the position to mount the bracket;
Placing the wireless module on bracket and secure it by 02 x M2 screws (supplied in accessory bag)

Note: The bracket can be mounted on the wireless module in both direction, upward or downward

The mounting bracket is made from hard metallic material. The following steps are for mounting this bracket;

Installation location

The bracket will be fixed on the wall or surface by 2 x M4 screws (supplied by customer) or double-sided 3M tape (included in accessory bag in carton box);

• DO NOT install the wireless module inside a complete metallic box or housing. The RF signal can not pass through metallic wall;
• This wireless module would be installed a semi-metallic box, because the RF signal can pass through the nonmetal wall/are;
• The best case is to install the wireles module inside or Non-metallic box;
  Some non-metallic materials: plastic, glass, wood, leather, concrete, cement…

IO Wiring & Sensor installation

The sensor module has M12-male connector which is matched with M12-female connector on wireless module;
Carefully plug the sensor module onto wireless module, using HAND to tighten slowly until stop;
Note: please DO NOT over tightening by hand or other tool, it can damages the M12 connector;

Power Supply & Battery installation

Steps for battery installation:

• Using Philips screw driver to unscrew M2 screw at the side of housing
• Carefully pull out the top plastic housing in the vertical direction

NOTE : Because of O-ring, it requires to have much pulling force at the beginning, therefore please do it carefully to avoid the damage of circuit board which is very thin (1.00mm);

• Insert the AA battery, please take note the poles of battery
• Insert the top plastic housing and locking by M2 screw

Troubleshooting

empty or not installed correctly

Reconfigure the led light function exactly as instructed

2| Wireless sensor not connected to co-ordinator| No power supply

The configuration function of the RF data rate is incorrect

| Check that the battery is empty or not installed correctly

Reconfigure the RF data rate with the button according to the instructions
