Simple Motion Sensor Alarm Light - Circuits DIY

The circuit is simple and has one transistor circuit to activate the buzzer and LED at its output. When the PIR sensor module detects any infrared signal it will send a signal to the circuit and switches on the transistor. This will activate the buzzer and a LED for a preset time period. The activation time period depends on the PIR sensor module.
