1. Introduction Thanks for your purchasing of this integrated multifunction indoor air quality monitoring sensor. It measures PM2.5 / PM10 / CO2 / Temperature / Humidity. To ensure the best product performance, please read this manual and retain it for future reference. 2. Unpacking Open your box and inspect that the contents are intact (nothing broken) and complete (nothing missing). Inside you should find the following: QTY Item Description 1 Particle Detection Sensor (PM2.
. Features Particle Detection Sensor Measures indoor PM2.5, PM10, CO2 concentration, Temperature and Humidity every 60 seconds when powered with USB or detecting every 10 minutes when powered with batteries only. USB connection for indoor use only CO2 value calibration function available on the device PM2.
of the WS View app (requires the gateway and your phone using the same Wi-Fi network) Displays current PM2.5 / PM10 concentration/AQI and 24H AQI and air quality level index on the Live Data page of the WS View app Displays current CO2 concentration and 24H average CO2 concentration on the Live Data page of the WS View app Displays temperature and humidity data where the sensor located Calibration function available for PM2.

4. Sensor Set Up 1.
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 3 seconds – flash once after 20s , 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.
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.
6. Wi-Fi Configure with gateway This Particle Detection Sensor doesn’t has a display function and you need to use our WS View App to view the data on your mobile application after pairing this device with our GW1000 Wi-Fi Gateway or HP2551/HP3500/HP3501/WH0295 console (all sold separately). 6.1 Pair with Gateway If GW1000 has been in operation, and you have never had any WH45 sensor setup before, just power up the sensor and GW1000 will pick sensor data automatically.
6.2 Wi-Fi Connection for the Gateway For this part, please refer to the manual of the GW1000 Wi-Fi gateway. Any question, please contact the customer service. 7. View Online Data on WS View When the Wi-Fi configuration is done, you can view the live data of your sensor on the WS View application.
Note: The WH45 sensor 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.
8. Appendix Air Quality Index (AQI) for the PM2.5 Concentration (24hr) AQI Air Pollution Level PM2.5 Concentration ug/m3 0 - 50 Good 0.0-12.0 51 -100 Moderate 12.1-35.4 101-150 Poor 35.5-55.4 151-200 Unhealthy 55.5-150.4 201-300 Severe 150.5-250.4 300+ Hazardous 250.
Air Quality Index (AQI) for the PM10 Concentration (24hr) AQI Air Pollution Level PM2.
1,000-2,000 ppm: level associated complaints of drowsiness and poor air 2,000-5,000 ppm: level associated with headaches, sleepiness, and stagnant, stale, stuffy air; poor concentration, loss of attention, increased heart rate and slight nausea may also be present. >5,000 ppm: This indicates unusual air conditions where high levels of other gases also could be present. Toxicity or oxygen deprivation could occur. This is the permissible exposure limit for daily workplace exposures.
9. Sensor Calibration CO2:There is an easy way to find the CO2 sensor is drifted or not: put the sensor in outdoor open air locations, away from any combustion exhausts, wait for 30 minutes, you should see the CO2 reading is 420ppm +/-10. If it is far from this reading, you can wait for some more time, and test it during night to confirm.
PM2.5: It is not possible to calibrate on the sensor side, and you can calibrate through WS View App when paired with GW1000 or on the console when paired with HP2551/HP3500/HP3501, which saves the offset value on the gateway side before sending data to www.ecowitt.net server. However if PM2.5 data is persistently low, it can be that there is a spider net going inside the sensor. So please clean the sensor from time to time to see if there is any sign of spider penetration.
