3 Pieces (3X) MQ-135 Ammonia (NH3), Nitrogen Oxides (NOx), Alcohol, Benzene, Smoke, and CO2 Hazardous Gas Sensor Detector Module This MQ-135 gas detector is used for leak detection of Ammonia (NH3), Nitrogen Oxides (NOx), Alcohol, Benzene, Smoke, and Carbon Dioxide (CO2). Suitable for home and industrial use, it has fast response and recovery characteristics, a long life and reliable stability. The module features dual signal outputs: An analog output (0V to ~5V), the higher the gas concentration, the higher the voltage, and a digital TTL level output to signal the presence or absence of gas. The TTL threshold is adjustable with the onboard potentiometer. Specifications:Operating voltage: 5 Volts DC (VCC Pin) Maximum power consumption: 800mW (160mA at 5V) Dual signal output (analog (AO pin) and TTL (DO pin) level output)The DO TTL output signal is normally low, goes high when gas is detected. The threshold is adjusted with the onboard potentiometerAO is a 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltageIndicator LEDsPowerDO (Digital Output On)Dimensions (approximate): 32mm x 20mm x 27mm LxWxH (1.25 x 0.8 x 1.1 inches)Weight: 7 gramsPackage Includes:3X MQ-135 Ammonia (NH3), Nitrogen Oxides (NOx), Alcohol, Benzene, Smoke, and CO2 Gas Sensor Detector ModuleLink to online Operating instructions and Schematic Get it faster!
