One USB Cable
User Manual

Features

PM2.5 Sensor

  • Measures indoor PM2.5 concentration every 60 seconds when powered with AC adaptor or detecting every 10 minutes when powered with batteries.
  • USB connection for indoor use only
  • Calibration function available when paired with Wi-Fi Gateway/HP2551/HP3500/HP3501
  • Long wireless range, up to 300 feet (100 meters) in open areas

When paired with a WH0290 console:

  • Console will synchronize with this sensor and the received data can be displayed on the console.
  • AQI index
  • Calibration function is not available with this console display. Max one sensor can be supported.

When paired with a Wi-Fi Gateway:

  • Monitor live sensor data on the Live Data page of the WS View Plus app (requires the gateway and your phone using the same Wi-Fi network)
  • Displays current PM2.5 concentration/AQI and 24H AQI and air quality level index on the Live

Data page of the WS View Plus app

  • Up to 4 channels supported.
  • Calibration function available

When paired with a Weather Station Console
(HP2551/HP3500/HP3501/WN1900/WN1920/WN1820)
:

  • View PM2.5 concentration data in real-time on the Display
  • Up to 4 channels supported. Channel names can be edited on the Display.
  • Calibration function available.

When uploaded to Ecowitt Weather Server:

  • View current sensor data & history records & graph on the website
  • Set and receive email alerts from the server
  • Channel names can be edited on the website
  • Remote monitoring with smart phone, laptop, or computer by visiting the website

Note: The WH41 and WH43 will be recognized as the same sensor type by the software. If you purchased both, they will share the four channels together and the total quantity of the two sensors could not exceed four.

Sensor Set Up

  1. Remove the battery door on the base of the air quality sensor as shown in Figure 1
    ecowitt WH43 Indoor PM2.5 Air Quality Sensor - Parts No| Description| No| Description
    ---|---|---|---
    1| Red LED Indicator (RF transmission)| 3| Battery Compartment Cover
    2| AC Adapter USB Power Port| 4| Battery Compartment

  2. Insert two AA batteries and close the battery door.
    Note: The batteries (not included) are mainly for backup purpose.

  3. Connect the USB cable between the sensor and an AC adapter(not included).

Note: After inserting the batteries or connecting AC power, the sensor LED indicator will light for four seconds, and then flash once per 1 minute thereafter (10 minutes if only powered by batteries). Each time it flashes, the sensor is  transmitting data.

Sensor Installation

Before install the sensor into its permanent location, you may go to Section 6 to configure with the gateway first. Once the sensor has been confirmed working correctly, then you can go back here.
Place the sensor on a horizontally surface. Note that the vents must be clear of any obstructions, and we recommend placement away from other electronic devices to prevent interference. Do not place on a metal table to prevent RF signal loss.
Wireless communication is susceptible to interference, distance, walls and metal barriers. We recommend the following best practices for trouble free wireless communication.

  1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs.
  2. Radio Frequency Interference (RFI). If you have other devices using the same RF frequency and communication is intermittent, try turning off these other devices for troubleshooting purposes. You may need to relocate the  transmitters or receivers to avoid intermittent communication.
  3. Line of Sight Rating. This device is rated at 300feet line of sight (no interference, barriers or walls) but typically you will get 100feet maximum under most real-world installations, which include passing through barriers or walls.
  4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum siding. If you have metal siding, align the remote and console through a window to get a clear line of sight.

Wi-Fi Configure with gateway

This PM2.5 sensor doesn’t has a display function and you need to use our WS View Plus App to view the data on your mobile application after pairing this device with our Wi-Fi Gateway(sold separately).
6.1 Pair with Gateway
If Wi-Fi Gateway has been in operation, and you have never had any WH41 PM2.5 sensor setup before, just power up the sensor and Wi-Fi Gateway will pick PM2.5 data automatically.
If a PM2.5 sensor has been hooked on Wi-Fi Gateway before, and you have a new PM2.5 sensor to replace the old one, unplug Wi-Fi Gateway from USB socket and power up again, then the new sensor will be learned and old sensor will  be erased.
Note: The gateway can support up to 4 PM2.5 air quality sensors (with GW1000/GW1100 Wi-Fi Gateway Firmware V1.4.6 or above). Each new sensor will be recognized as a new channel according to the Power-on sequence. You may attach a label of the channel on each sensor for distinction.

6.2 Wi-Fi Connection for the Gateway
For this part, please refer to the manual of the GW1000/GW1100 Wi-Fi gateway.
Any question, please contact the customer service.

View Online Data on WS View Plus

When the Wi-Fi configuration is done, you can view the live data of your PM2.5 sensor on the WS View Plus application.

ecowitt WH43 Indoor PM2.5 Air Quality Sensor - Data

Note:
The PM2.5 data can be only viewed on the Live Data interface since it doesn’t support uploads to weather underground.
If you choose to upload the data to our weather server: https://www.ecowitt.net, you can view the live data/history graph and download the records on the website. You can add a shortcut of the website on the home screen of your phone  for quick access.
