We have built a very simple Motion detector circuit here. We are using a HC-SR501 PIR Sensor, an LED (which will glow whenever there is a motion infront of the sensor) and resistor.

In this DIY project we build a Motion detection alarm by interfacing a PIR sensor with TI-MSP430 launchpad.

This motion sensor light project, utilizing a PIR sensor and relay, illuminates a bulb when detecting human motion. Simple and versatile, it finds applications in security systems and basic automation ...

Circuit diagram of the PIR Motion Sensor Light and Switch based on SB0061 shown here can be used for security or corridor lighting in power saving mode. The 12V DC supply required for the whole ...

The PIR sensor is kept external to the enclosure and wired up into the tree itself. This allows the sensor to still detect motion in the room while the rest of the circuit is hidden away.
