Ecowitt WH46D Indoor 7-in-1 Air Quality Sensor with LCD, CO2, PM1/PM2.5/PM4/PM10
The WH46D indoor sensor adds particle detection of PM1.0, PM2.5, PM4, PM10, along with CO2, Temperature and Humidity readings to your weather station.
The WH46D can be used as a standalone monitor as it has a built in LCD display. With a suitable gateway or weather station console you can upload to the Ecowitt network to store historic of the data as well as view near realtime readings.
Unlike some other brands, the Ecowitt WH46D can be used with a variety of consoles and gateways, click here to view the latest Ecowitt sensor matrix.
