An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

For this, we need a light sensor to detect the light condition and some circuitry to control the Light sensor. It’s like Dark and light Detector circuit but this time we are using Arduino to get more ...

Based off of the sound sensor from the Arduino Circuit Playground, there can be three stages: quiet, loud, and disturbing. Quiet sound levels means that no light sensor goes off. Loud means that the ...

Intersil’s ISL29125 is a low power, high sensitivity RGB color light sensor with an I2C interface.Its state-of-the-art photodiode array provides an accurate RGB spectral response and excellent light ...

Step 3: Making the Circuit. 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 ...

The block diagram of the motion sensor alarm is shown in Fig. 2. Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor ...
