WH43 Indoor PM2.5 Air Quality Sensor

Product Information: Indoor PM2.5 Air Quality Sensor

Model: WH43

The Indoor PM2.5 Air Quality Sensor (Model: WH43) is a wireless
sensor that measures the concentration of PM2.5 (particulate matter
with a diameter of 2.5 micrometers or less) in indoor environments.
It is designed to provide accurate and real-time air quality data
to help you monitor and improve the air quality in your
surroundings.

Features:

• PM2.5 Sensor: Measures indoor PM2.5 concentration every 60
  seconds when powered with AC adaptor or 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.

The sensor can be paired with different devices for various
functionalities:

When paired with a WH0290 console:

• The console will synchronize with the sensor, and the received
  data can be displayed on the console.
• AQI (Air Quality Index) calibration function is not available
  with this console display.
• Supports a maximum of one sensor.

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 to be connected to
  the same Wi-Fi network).
• Displays current PM2.5 concentration/AQI and 24H AQI (Air
  Quality Index) and air quality level index on the Live Data page of
  the WS View Plus app.
• Supports up to 4 channels.
• Calibration function available.

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

• View real-time PM2.5 concentration data on the display of the
  Weather Station Console.
• Supports up to 4 channels.
• Channel names can be edited on the display.
• Calibration function available.

When uploaded to Ecowitt Weather Server:

• View current sensor data, history records, and graphs on the
  website.

   1. If using batteries, insert them into the sensor. If using an AC
      adaptor, connect it to the sensor.
   2. Ensure the sensor is powered on and ready for pairing.
   3. If calibration is required, pair the sensor with a Wi-Fi
      Gateway/HP2551/HP3500/HP3501.
2. Sensor Installation:

   The sensor should be installed in an appropriate location for
   accurate air quality measurement. Follow these guidelines:

   1. Place the sensor in a well-ventilated area, away from direct
      sunlight and heat sources.
   2. Avoid placing the sensor near sources of pollution or airflow
      disturbances.
   3. Ensure the sensor is positioned at a suitable height for
      accurate readings.
3. Wi-Fi Configure with gateway:

   To connect the sensor to a Wi-Fi Gateway, follow these
   steps:

   1. Pair the sensor with the Wi-Fi Gateway.
   2. Configure the Wi-Fi connection between the gateway and your
      network.
4. View Online Data on WS View Plus/Ecowitt:

   To view the sensor data online using WS View Plus or Ecowitt,
   follow these steps:

   1. Ensure the sensor is paired with a compatible device (e.g.,
      Wi-Fi Gateway, Weather Station Console).
   2. Access the Live Data page of the WS View Plus app or visit the
      Ecowitt Weather Server website.
   3. Monitor the current PM2.5 concentration, AQI, and other
      relevant air quality information.

2. Insert two AA batteries and close the batterydoor. 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.
5. 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.
7

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.

6. 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.
7. 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.
10

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.
