Lansen WM-Bus Air Quality Sensor with VOC LAN-WMBUS-E-VOC

Lansen's combined VOC, ambient temperature and humidity measurement product is a plug-and-play transmitter. The device has 2 antennas for maximum range in both vertical and horizontal directions. The built-in VOC sensor is used to measure VOC (air quality) gases. The sensor is a high performance sensor with minimal drift and reliable performance even over long periods of time. The VOC sensor uses a moving average algorithm and a baseline compensation algorithm to detect poor air quality. This technique detects changes in air quality, but cannot typically be used to detect a constant air quality problem over long periods of time. Note that the first accurate reading can typically be expected after 24 hours.
