Gravity formaldehyde (HCHO) sensor is an Arduino & Raspberry Pi compatible module which is the ideal solution for indoor air quality monitor. It can be used to measure HCHO in air. This sensor module is widely used in many air testing applications, such as indoor air quality, real time quality monitoring stations. HCHO sensor module can detect and measure HCHO accurately. Many advantages are available, such as strong anti-jamming capability, high stability, ATC, high sensitivity (up to 0.01ppm) and long life (2 years in air). Integrated with Gravity Interface which is easy to used, wide input voltage, and optional output signal, our module can be almost compatible with all MCU. According our sample codes, an HCHO detector can be made very quickly. This is a formaldehyde (HCHO) sensor module with small size and Arduino compatibility.
