PIR sensors, often referred to as, "Passive Infrared" or "IR motion" sensors, enable you to sense motion. Everything emits a small amount of infrared radiation (IR), and the hotter something is, the more radiation it emits. PIR sensors are able to detect a change in average IR levels of their detection zone (e.g. when a human enters a room, that room will increase in temperature slightly) and hence sense motion.
This one's great, as it can be powered via the Raspberry Pi's 5V output, and be read directly from the Raspberry Pi's GPIO input (as the sensor has a digital 3.3V output!)
This PIR includes an adjustable delay before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and two M2 mounting holes! It runs on 4.5V-20V power (or 3V by bypassing the regulator with a bit of soldering) and has a digital signal output (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100 degree cone.

Note 2: SNZB-03 must be used with Zigbee Bridge.
Description:
If your concern is not only about home security but about using motion to turn on or off the lights, well, SONOFF SNZB-03 might be the answer for you.
This ZigBee motion sensor is an extra-handy smart device for placing anywhere in your home to detect motion and trigger alarms. That means the sensor will send an instant alert notification to your mobile phone whenever the motion is detected if this security system is armed. If you have a SONOFF ZigBee Bridge, you can connect the sensor to it to activate Wi-Fi devices, not merely ZigBee devices. For example, you can set a scene for your living-room light so that it will automatically turn on when you walk through the living-room.
Boasts 110°view field and 6m detection rang and you can early receive an alert message of someone’s presence, accordingly taking measures to reduce the possibility that your house is threatened. Share control is available for multiple users to check and monitor your home together. Easy and tool-free installation, 3M adhesive installation significantly saves your time. Powered by a battery which makes it convenient to stick it on any place that you want to monitor.
You will get a notification of low-battery level when the battery life reaches 10% remaining.
Features:
Create smart scenes to activate Wi-Fi smart devices.
Detect movement and trigger alert messages.
Turn on/off the devices through your movement.
Work with the SONOFF camera to monitor your home.
6m detection distance and 110°viewing angle.
Share the sensor to your family to together keep eyes on your home.
