سنسور تشخیص گاز مونوکسید کربن MQ-9

Sensitive material MQ-9 gas sensor SnO 2, With lower conductivity in clean air. This makes the detection method cyclic high and low temperature and detects CO at low temperature (heats up at 1.5 V). The conductivity of the sensor is higher along with an increase in gas concentration. At high temperature (heated to 5.0 V), it detects methane, propane, etc. flammable gas and purifies other gases adsorbed at low temperature. Use a simple electrical circuit, convert the conductivity to match the output signal of gas concentration.

The MQ-9 gas sensor is highly sensitive to carbon monoxide, methane and liquefied gas. The sensor can be used to detect various gases containing CO and flammable gases, it is low in price and suitable for various applications.

* Good sensitivity to CO / flammable gas

* High sensitivity to methane, propane and CO

* Long life and low cost

* Simple drive scheme

Application

* Home gas leak detector

* Industrial gas detector

* Portable gas detector
