Netvox – R720E-Wireless TVOC Detection Sensor
Netvox – R720E-Wireless TVOC Detection Sensor
Description
R720E-Wireless TVOC Detection Sensor
R720E is a wireless communication device that detects temperature, humidity, and TVOC. TVOC refers to all organic gaseous substances in space, and generally refers to indoor volatile organic substances. TVOC is also the much serious one of the three types of pollution affecting indoor air quality. R720E can detect the concentration value of TVOC.
