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 2
00 to 10000ppm.
Specification:
- Signal output indicator
- Dual Signals output (analog output and TTL output)
- TTL output signal is low level, allows to connect with SCM directly
- Analog output 0~5V voltage
- High sensitivity
- Long working lifetime and stable performance
- Quick response and recovery
Technical Data:
- Chipset: LM393 / MQ-4 sensor
- Working voltage: DC 3~5V
- Detecting range: 300~10000ppm
