When motion is detected, the sensor signals the Arduino Nano, which triggers the relay and activates the bulb. The relay acts as a switch to enable or disable the connected 230V AC, 60W bulb according ...

The circuit involves a PIR sensor as the motion detector, a relay to control the power to the bulb, and a transistor to drive ... LOW after a time duration set by the user. So the light which is ...

PIR Sensor Pin (PIR_INPUT): Connect the signal pin of the PIR sensor to digital pin 2. Arduino code written entirely in C++ without utilizing sleep mode functionality. Controls an LED based on motion ...

The main aim of this mini-project is to demonstrate the working of a PIR motion-based light bulbs. This is to ... of the voltage regulator is connected to the bread board that acts as a 5V Source for ...

an Arduino Uno, a relay module, and a light bulb showcases the potential of leveraging technology for practical applications. This motion sensor-based lighting system not only enhances convenience but ...

We’ve previously shown how to control lights with a 433 MHz PIR motion sensor via a 433MHz to WiFi bridge based on an ESP8266 WiFi module itself commanding Sonoff Basic wireless switches connected to ...

This Arduino ... light is shown in Fig. 2. It is built around an Arduino Uno board (board1), PIR sensor connected across CON2, two BC547 npn transistors (T1, T2), a 12V one changeover relay (RL1), ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and ... With everything connected, it’ll turn on automatically. You can even plug a light or another device ...
