MQ-4 MQ4 GAS METHANE SENSOR MODULE

Detail MQ-4 MQ4 GAS METHANE SENSOR MODULE

Sensitive material MQ- 4 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-4 Methane gas sensor of high sensitivity, propane, butane and has a good sensitivity. The sensor can detect a variety of combustible gases, especially natural gas, it is a low-cost sensor suitable for a variety of applications.

FITUR DAN SPESIFIKASI :
- Using high-quality dual-panel design,with power indicator and TTL signal output instructions.
- The switching signal having a DO (TTL) output and analog output AO.
- TTL output valid signal is low. ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
- Analog output voltage with the higher concentration of higher voltage
- There are four screw holes for easy positioning.
- Has a long life and reliable stability
- Rapid response and recovery characteristic
- Input voltage : DC5V Power consumption ( current ): 150mA
- DO output : TTL digital 0 and 1 ( 0.1 and 5V)
- AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V

KELENGKAPAN :
- 1pcs MQ-4 gas methane sensor module
