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.
Coaxial pigtails are used to connect wireless radios to antennas and other equipment. This series features pigtails which support U.FL connectors & 1.13 Mini Coax.
