Description

MQ135 Air Quality Detector Sensor Module in Pakistan

 

This MQ135 Air Quality Detector Sensor makes use of the MQ-135 air quality detector and hazardous detector chip. there is an LM393 analog comparator on this module. This comparator chip on this module makes it easy to integrate into a project that can detect hazardous gases. this air quality detector sensor requires a 5V power supply. this module also provides a digital logic output which is 0 or 1 and an analog level output (0 to 4)V. There is also the MQ136 Hydrogen Sulfide Detection Sensor of this website.

if there is digital logic output is LOW it means there is no gas is detected. but if there is gas detected than the output logic is HIGH.  On the other hand, When the hazardous gas concentration in the environment reaches the set threshold via a potentiometer on the module. then the analog level output provides an output voltage within the range of 0 to 4 Volts based on the concentration of the hazardous gas in the environment. if the concentration is lowest then the volts are 0. if the concentration is maximum then volts will be 4. by this module we can detect hazardous gases such as Ammonia, Nitrogen Oxide, Alcohol, Benzene, Smoke (Carbon Monoxide), Carbon Dioxide and other air contaminants in your DIY projects. all types of gas sensors are available at epro.pk.

This air quality Detector module has lower conductivity in clean air. If there is target combustible gas exists then the conductivity of the sensor is higher along the gas concentration rising. This MQ135 module convert change of conductivity to the corresponding output signal of gas concentration. This MQ135 air quality sensor has a high sensitivity to ammonia, sulfide and benzene steam. This module is also sensitive to smoke and other har, fuel gases. It is very low cost and suitable for different applications such as harmful gases/smoke detection.
