MQ306A Flammable Propane Gas Sensor

The MQ306A is a Flammable Propane Gas Sensor. Main ratings: Heater voltage 0.90V ± 0.10V (AC or DC); Circuit voltage Less than 6V DC (polarity is important); Load resistance Variable (>10 KOhm) , P S < 10 mW; Heater current Less than 120 mA. This page brings together the MQ306A key specifications, with the full datasheet PDF to preview below or download.

MQ306A is a flammable gas sensor that detects the concentrations of combustible gas in the air and outputs its reading as an analog voltage. The sensor belongs to the MQ series of gas sensing modules, infamously known for their reliability and quick response time in terms of reporting harmful concentrations of dangerous gases in their immediate vicinity. The sensor is suitable for LPG (liquid petroleum gas), LNG, iso-butane, propane, and H2(Hydrogen gas) detection. MQ306A is easily interfaceable with virtually any kind of MCU (Arduino Uno, NodeMCU) and can also be used for analog data extraction for measuring changes in the gaseous concentration of harmful gases.

MQ306A gas sensor is widely used in domestic flammable propane gas concentration alarms, industrial flammable gas alarms, and portable propane gas concentration detectors. The module also features ESD protection and overvoltage protection capabilities.
