Environmental Sensors Dealers in Hubli

• Feature: Good sensitivity to a wide range of combustible gases,High sensitivity to Natural gas,Long life and low cost.

The sensor’s output is an analog resistance. The 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. The sensitive material of the MQ-4 gas sensor is SnO2 which has lower conductivity in clean air, in the presence on CNG, the sensors conductivity rises proportionally with the amount of CNG.
