Check the listing for details. MQ-5 Methane LPG Natural Gas Propane Sensor Detector Module For Arduino US. Condition: New. Listed at 6.49 USD. MQ-5 Methane / Propane / Butane / LPG / Natural Gas / City Gas Sensor Detector Module This MQ-5 gas detector is used for leak detection of LPG (Liquified Petroleum Gas), methane, propane, butane, natural gas and city gas, with low sensitivity to alcohol and smoke. 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)TTL output signal is normally low, goes high when has is detected. The threshold is adjusted with the onboard potentiometer0 ~ 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:1X MQ-5 Methane / Propane / Butane / LPG / Natural Gas / City Gas Sensor Detector ModuleOperating instructions and Schematic Get it faster!
