KitsGuru MQ4 - Natural Gas, Methane Gas Module Electronic Components Electronic Hobby Kit

This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance.1. Good sensitivity to Combustible gas in wide range2. High sensitivity to Natural gas3. Long life and low cost4. Simple drive circuitThe drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC .This sensor comes in a package similar to our MQ-3 alcohol sensor.1. Ambient temperature: -20 ~ + 552. Humidity:
