Abstract: The work gives a report about the design of an energy saving system using a Passive Infrared Radio sensor to switch `off' fan and light circuits in the classroom in the absence of students.

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 ...

The PIR sensor deactivates the output with a delay of 3 seconds. Flushing starts by opening the solenoid valve by applying a short 9V DC voltage pulse to the solenoid. Flushing ends by applying a ...

Code explanation of the Arduino PIR Interfacing. The code explanation of the code is as follows. The complete code can be found at the absolute bottom of the blog. const int pirPin = 5; This line ...

Hi there! I hope you are doing great. Today I am sharing the Proteus simulation of my project, in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor ...

Aside from the single-board computer and the car horn, it uses a relay board, a 12-volt battery, and a Raspberry Pi-compatible camera, such as the official module or just any old webcam.

Triggering mechanism schematic: We can use a PIR sensor on 5V [some even works on 3.3 Volt] to trigger the Pin-13 of ESP32 Camera. However, to make it fully isolated, we recommend to use an ...
