Model: G805C

Multi-parameter Air Quality Multi-principle module (CO2 via NDIR)

5-in-1 module: simultaneous CO2 + HCHO + PM2.5 + temperature & humidity output

G805C 5-in-1 Air Quality Sensor Module (CO2/HCHO/PM2.5/Temp/RH)

The G805C is a cost-effective 5-in-1 air quality module from Yixin that simultaneously outputs carbon dioxide (0-5000 ppm), formaldehyde (0-1500 µg/m³), PM2.5 particulates (0-1000 µg/m³), temperature (0-125 ℃, ±0.3 ℃) and humidity (0-100%RH, ±2%RH), with T90 < 120 s. Stable, rich in interfaces, low power and with excellent long-term stability, it is widely used in air purifiers, fresh-air systems, smart homes, air quality monitors and consumer electronics.
