MQ-2B Smoke Sensor Liquefied Gas Hydrogen Detection Probe Combustible Gas Alarm Smoke Sensing Element
Basic Overview:
The MQ - 2B gas sensor adopts tin dioxide (SnO2) as its gas - sensitive material. This material has low conductivity when exposed to clean air. When flammable gases or smoke appear in the surrounding environment, the conductivity of the sensor will increase as the concentration of the target substances rises. By connecting the sensor to a simple circuit, the change in its conductivity can be converted into an output signal that corresponds to the concentration of the detected gas or smoke, so as to achieve the purpose of gas concentration detection.
Core Features:
Typical Applications:
It is widely used in various gas detection equipment. It is a core component in household gas leakage alarms, which can timely warn of gas leakage risks. In industrial settings, it is applied to industrial flammable gas alarms to ensure the safety of the production site. Additionally, it is also suitable for portable gas detectors, facilitating on - site and mobile gas detection work.
