The gas sensor with an MQ-135 sensing element detects ammonia, aromatic compounds, sulfur compounds, benzene vapors, smoke, and other harmful gases. It can be used in hazardous gas detection devices for residential or environmental spaces. The analog output increases as the gas concentration rises, while the TTL digital output goes low when a valid signal is detected.
The sensing element has a fast response and recovery time, as well as a long service life and stable operation. It operates at a DC voltage of 5 V.
