TECHNICAL DATA MQ3 GAS SENSOR SparkFun …

Structure and configuration of MQ3 gas sensor is shown as Fig. 1 (Configuration A or B), sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel net. The heater provides necessary work conditions for work of sensitive components. The enveloped MQ3 have 6 pin ,4 of them are used ...


MQ135 Gas Sensor with Arduino Code and Circuit Diagram

20210201· But, in this project, we will only play a buzzer. We will also include one red and one green LED. Circuit Diagram for MQ135 gas sensor. We are going to receive analog values from the sensor. We used the Arduino A5 pin. So we connected the A5 pin with the 4th pin in the sensor. The sensor GND and VCC goes to Arduino GND and 5volt.
