The Arduino MQ-5 gas sensor module's coding is straightforward. We're simply reading the Sensor's analog data and turning the LED and Buzzer ON or OFF. Please bear in mind that we are just processing ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

Sound Sensor with Arduino UNO – Connection Diagram. Now that we have a complete understanding of how a Sound sensor works, we can connect all the required wires to Arduino as shown below. Connecting ...

Arduino board Vin pin is connected to battery, so the board generates 5V supply from onboard 7805 voltage regulator chip, which is given to DHT11 and 433MHz RF transmitter module (TX1). The sensor ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...
