How mq3 sensor works
WebWhile the sensor works perfectly for measuring relative amount of alcohol in the air, we will have to work a bit harder to get the exact readings. We have already mentioned why and how does the MQ3 send 0-5V voltage through the analogue output AO. For starters, we will read off the values on the analogue Croduino pin A0 (0-1023). Web25 jul. 2024 · The IR sensor has three pins which are VCC, ground and output pin. Connect the VCC of the IR sensor with the 5V of the Arduino. Connect the ground of the Arduino with the ground of the IR sensor. Connect the output pin of the IR sensor with the digital pin 8 of the Arduino. Now after interfacing the IR sensor with Arduino we will connect the ...
