The TB600B-Series Formaldehyde Gas Module is the perfect combination of a state-of-the-art high-precision sensing device with a sophisticated circuit board. The sensor module uses EC Sense’s small-in-size solid polymer electrochemical sensor, which accurately detects very low concentrations of gases. It replaces our nose to reliably sniff out the gas concentration and enables precise gas detection. The TB600B module serves an UART digital output for ease-of-use, eliminating the need for customers to understand the sensor application and the tedious work of calibration.
