The H8054 Mini PIR motion detection module is designed to provide basic motion detection to your project.
This is a very small light sensor. A photo resistor (also known as a photodector, or photocell) changes resistance depending on the amount of light it is exposed to.
The HC-SR501 is a passive infro-red (PIR) sensor which is used to detect motion based on the infrared heat in the surrounding area.
SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader.
This is a 2.5mm x 5.5mm right angle barrel plug with 6ft of 18 gauge wire. This will plug into our camera receivers and some of our cameras.
