It accurately measures a wide range of harmful gases including NH3, NOx, CO2, and smoke within 10-1000 ppm, delivering fast response times under 1 second. With low power consumption and ready-to-use connectivity, it’s perfect for smart home, environmental monitoring, and safety applications. Comes with detailed eBooks and technical support to ensure smooth integration and rapid prototyping. ## Description The AZ-Delivery MQ-135 air quality sensor is a ready-to-use module for Arduino and Raspberry Pi to measure the concentration of various toxic gases such as benzone, alcohol, smoke and airborne pollutants. The MQ-135 measures a gas concentration from 10 to 1000ppm and is ideal for detecting a gas leak, as a gas alarm or for other robotics and microcontroller projects.The MQ series sensors use a small heating element with an electronic-chemical sensor, which are suitable for indoor use.The sensor has a high sensitivity and fast response time, but needs a few minutes to give accurate readings because the sensor needs to heat up first. The measured values of the sensor are output as analogue values, which can be easily evaluated with a microcontroller.This sensor is ready for connection to a microcontroller, such as an Arduino board. For use with a Raspberry Pi an additional AD converter is required.Pin assignment:VCC - power supply 5VGND - ground connectionAOUT - Analog OutputDOUT - Digital OutputThe module has a potentiometer for setting the threshold value. At the digital pin, the sensor outputs only a 0 or 1, depending on whether the set threshold value is exceeded.Caution: The sensor gets warm during operation!For further ideas and projects please visit our blog on the internet or download our free eBooks on our website!AZDelivery is a trademark which is registered at the DPMA (German Trademark and Patent Office).
