This project explains about a complete Automatic PIR Motion Sensor Light Circuit, it is very useful for home and outdoor lighting, because the circuit uses a PIR sensor. Whenever the PIR sensor detects motion, it turns the light ON automatically and after a preset delay, it turns the light OFF, saving power and reducing human […]

Simple PIR Sensor Timer Circuit using Transistors
This article presents a simple PIR sensor timer circuit using transistors; the circuit costs little, is easy to build, and operates from a 12 V DC power supply. When the PIR sensor detects motion, the output stays ON for a preset time and then turns OFF automatically after the delay, hence, this feature makes the […]
PIR Sensor Motion Alarm Circuit Transistor and Relay
Nowadays, security is very important that why homes and shops need protection; so to safeguard this motion sensor circuits are useful. The PIR Sensor Motion Alarm Circuit with Transistor and Relay is simple because it uses only a few components, costs very little, and is easy to build. The circuit works using a PIR sensor […]
Bluetooth Controlled Police Siren Sound Circuit with Arduino
Nowadays, Arduino projects are very popular and they controls everything, as they are easy to build and they are useful for learning electronics. This project demonstrates a Bluetooth-Controlled Police Siren Sound Circuit with Arduino, then the Arduino UNO acts as the main controller, while the Bluetooth module provides wireless control. Furthermore, with Bluetooth we can […]
Arduino Touch Sensor Relay Circuit
Want to control appliances by touch? then this circuit makes it possible, as this Arduino Touch Sensor Relay Circuit uses Arduino and touch sensor. The Arduino reads the touch signal and uses the relay as a toggle switch. When we touch the sensor once, the relay turns ON and when we touch the sensor again, […]
Solar Water Pump Circuit using Battery and MOSFET
In my earlier article I showed about solar water pump circuit using relay, that design works, but relay makes clicking sound and relay contacts can burn after long use. So now here is the new version and this project is Solar Water Pump Circuit using Battery and MOSFET instead of relay, as MOSFET has no […]
