Natural gas sensor MQ-4
$20.00
The natural gas sensor uses MQ-4 gas sensor, which can detect alcohol very sensitively. Through the 3P sensor connection line, it can be directly plugged into the Arduino uno controller for easy programming. Combining the buzzer module and relay module, you can make products such as natural gas leak alarms. It is an ideal sensor to make indoor air meet environmental protection standards.
