Air Quality Monitoring using NodeMCU and MQ2 Sensor IoT ...

· Due to the high sensitivity and fast response time of it. But, in this design, we used the MQ2 sensor for the smoke situation. This sensor has four outputs, namely, Vcc, ground, D0, and A0. Architecture. Firstly, to make an IoT based Air Quality Monitoring system will be collecting the data from the mq2 senor and send to NodeMCU. We will then be sending this data to aws IoT core using MQTT ...

Arduino lesson – MQ2 Smoke Sensor –

· Arduino MQ2 Smoke Alarm. The circuit we will build is shown below. So to power the smoke sensor, we connect pin 2 of the smoke sensor to the 5V terminal of the arduino and terminal 3 to the GND terminal of the arduino. This gives the smoke sensor the 5 volts it needs to be powered. The output of the sensor goes into analog pin A0 of the arduino.

Configure and read out the Raspberry Pi gas sensor (MQX)

Sensors are necessary to detect the components of the air. These are used in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown. Thus, smoke detectors or air quality testers can be built. How to configure any MQ sensor and read it out with the Pi will be shown on the example of the Raspberry Pi gas sensor MQ2 in this tutorial. All other sensors ...

MQ2 Smoke Sensor with Raspberry Pi. The smoke sensor we will use is the MQ2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it outputs. Conversely, the less smoke that it is exposed to, the less voltage it outputs.
