MQ-135 Gas Sensor Module For NH3, Alcohol, benzene, smoke , CO2 Detector Module

Features:

• This gas sensor works between 2.5V to 5.0V.
• Uses around 150mA of current while running.
• It can detect gases like NH3, NOx, CO2, alcohol, benzene, and smoke.
• When powered at 5V, it gives out a digital signal from 0V to 5V in TTL logic.
• it also provides an analog output in the same voltage range. Typically, it operates at 5V.
