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

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 ...

An IR sensor module, which is used to detect fan’s blade to calculate the rpm, is connected to interrupt 0 means D2 pin of Arduino. Here we have used a stepper motor driver namely L293N module. IN1, ...

3D Scanner Machine Using Arduino (IR sensor based) This is a student project for making a simple 3D scanner using Arduino, two stepper motors and an IR sensor. It rotates the object on a turntable and ...

The circuit is based around this Sputnik-looking standalone IR temperature sensor which, as [MakeFunStuff] aptly describes, is “a single-pixel infrared camera that picks up everything in a 90 ...

IR_Sensor_With_Arduino Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1), Arduino Nano (Board1), LM386 audio amp (IC1), and 8-ohm speaker.
