Elecbee 10 件装 MQ-2B 传感器气体传感器 CO CO2 烟雾检测 MQ 传感器 DIY 用于安全检测系统

概述：

- The gas sensing material used in the MQ-2B gas sensor is tin dioxide (SnO2) with lower conductivity in clean. When there is a flammable gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of flammable gas in the increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.

- The MQ-2B gas sensor is highly sensitive to propane 和 smoke和for the detection of natural gas 和 other flammable vapors. This sensor detects multiple flammable gases和a low-cost sensor for a wide of applications.

This product has good sensitivity to propane, smoke, etc. in a wide concentration , 和 has the advantages of long life, low cost, 和 simple driving circuit.

应用：

Widely used in household gas leak alarms, industrial combustible gas alarms 和 portable gas detection instruments.
