IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. ... Here is the diagram of my Arduino infrared close proximity sensor ...

In the below image, you can see the actual hardware setup developed by using our Arduino sensor circuit diagram as a reference. ... This line defines “SENSOR_1_PIN” as pin 2 and “SENSOR_2_PIN” as pin ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

Besides the Arduino Nano, I used an ultrasonic sensor and an infrared sensor module. Description: The infrared sensor module detects the movement, which will wake up the Nano from sleeping and the ...

Arduino based Fire Alarm – Circuit and Working. Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V through Arduino, its trigger ...
