The H8054 Mini PIR motion detection module is designed to provide basic motion detection to your project.
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.
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.
This kit includes circuit breakers, wire, switches and more to wire the power to your WC800-DM4, 4WD All Terrain Robot Platform
