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.

The basic circuit using the PIR sensor was simulated on the breadboard which on sensing any motion (hand movement) turned the LED lights on, the serial monitor recorded the detection of motion, and ...

Fig. 1: Circuit diagram for Motion Activated Tap Water Flow Circuit Before understanding the working of the project, let us understand the workings of the PIR motion sensor, which is the heart of this ...

This project implements a smart room ventilation system using Arduino, combining both analog and digital sensors to respond to environmental conditions. The system activates a fan (represented by an ...

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada.

In this article, we will interface TSL25911Ambient Light Sensor Module with Arduino. This article discusses the working of the TSL25911 sensor module along with the circuit diagram and Arduino code ...

To be frank, using a microcontroller is probably overkill for most motion detector safety light circuits because the PIR sensor module itself can handle the task effectively.
