Description
Description:
This is a commonly used smoke sensor that uses MQ-2 combustible gas and smoke sensor components. The gas sensing material used in this component is tin dioxide (SnO2) which has a low electrical conductivity in clean air. 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 air increases. The sensor is highly sensitive to liquefied gases, propane and hydrogen, and is ideal for the detection of natural gas and other combustible vapors. It detects a wide range of flammable gases and is a low-cost sensor for a wide range of applications.
The sensor is compatible with various microcontroller control boards, such as the microcontrollers. We provide a method for using this sensor in conjunction with the UNO R3 microcontroller. When using, the A0 terminal reads the analog value of the corresponding gas; the D0 terminal is connected to an LM393 chip (comparator), we can adjust the measured gas alarm critical point through the potentiometer, and output the digital value at D0. When the measured gas content exceeds the critical point, the D0 terminal outputs a low level; when the measured gas content does not exceed the critical point, the D0 terminal outputs a high level. The sensor comes with a 2.54mm anti-reverse plug white terminal. When in use, we can connect to the MCU with DuPont cable. To facilitate wiring, we specially designed an expansion board that is fully compatible with this sensor and the UNO R3 microcontroller. We only need to stack the expansion board to the UNO R3 MCU, and use a 4P double-head XH2.54 plug wire (anti-reverse) to connect to the expansion board, which is simple and convenient.
At the same time, the sensor comes with 4 3mm diameter positioning holes, which allows you to fix the sensor to other devices.
