Specification

Description

Gas Detector Sensor Module is at a low cost and suitable for different applications such as harmful gases/smoke detection. If you are want to make a device that is used to detect Ammonia, Sulphide, and Benzene steam, also sensitive to smoke and other harmful gasses from the desired distance, then this sensor is needed for you. you can buy this sensor from KitsGuru.com at a reasonable price.

The MQ 135 Air Quality Detector Sensor Module For Arduino has lower conductivity in clean air. When the target combustible gas exists, the conductivity of the sensor is higher along with the gas concentration rising. It is to convert the change of conductivity to the corresponding output signal of gas concentration. The MQ135 gas sensor has a high sensitivity to Ammonia, Sulphide, and Benzene steam, also sensitive to smoke and other harmful gases.

  • MQ-135 Air Quality Sensor Hazardous Gas Detection Sensor
  • Input voltage : DC 5V ; 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 ) , maximum concentration of a voltage of about 4V
  • VCC: positive power supply (5V) ; GND: power supply is negative
  • Fast response and high sensitivity.
