Fermion HCHO Formaldehyde Analog Gas Sensor

The Fermion HCHO Formaldehyde analog gas sensor uses advanced MEMS technology to improve the air quality in your home or office. This sensor is specifically designed to efficiently and reliably detect formaldehyde gas, with a measurement range of 0-3 ppm. Its compact design (13x13x2.5 mm) and low power consumption (less than 20 mA) make it an ideal choice for portable detectors as well as permanently installed air purifiers and HVAC systems. The sensor responds quickly and reliably, which is particularly important in environments where good air quality is essential. To read out the gas sensor with an Arduino, connect the analog output pin of the sensor to an analog input pin of the Arduino. Then use the analogRead() function in your Arduino sketch to measure and process the sensor values.

Info: This sensor can only indicate whether a substance is present and only provides an approximate guideline value. For accurate measurements, we recommend purchasing the Gravity series with factory-calibrated electrochemical gas sensors.
