Description

Grove Formaldehyde Sensor is one of the Sensor Grove toolsets that standardized connectors of SFA30 Formaldehyde Sensor and make it modularly. With a Base Shield, it simplifies the process of detecting formaldehyde significantly. The primary module is made by SENSIRION based on electrochemical sensing technology optimized for the lowest false alarm rates. The basic theory is that the gas concentration signal decomposes the electrolyte into positive and negative charged ions, and the signal is transmitted through the electrode.

Grove Formaldehyde Sensor has low cross-sensitivity to alcohol and it also has long-term stability for as long as 6 years because of advanced anti-dry technology. It is factory-calibrated and can be easily connected with the I2C or UART interface into your device. The integrated Sensirion RHT sensor compensates fully for temperature and humidity guaranteeing a dependable function in changing indoor environments. And the low power consumption allows for battery operation. This makes Grove Formaldehyde Sensor a reliable, easy-to-use, and high-quality HCHO&RHT combo sensing solution.
