Gravity: Formaldehyde (HCHO) Sensor (Arduino & Raspberry Pi Compatible)

Gravity: Formaldehyde (HCHO) Sensor (Arduino & Raspberry Pi Compatible)Formaldehyde (HCHO) sensor is an Arduino & Raspberry Pi compatible module, which is the ideal solution for indoor air quality monitor. This is a HCHO(CH2O) sensor module. It can be used to measure HCHO in air. Through it, you can know the air quality. This sensor module is widely used in many air testing applications, such as indoor air quality, real time quality monitoring stations. Our HCHO sensor module can detect and measure HCHO accurately.
