Passive Infra-Red (PIR) sensors are used to detect motion based on the infrared heat in the surrounding area. This makes them a popular choice when building a system to detect potential intruders or people in general. These sensors can take for 10-60 seconds to warm up, so try to avoid motion during that time.
Basic motion detection.
The H8054 PIR motion detection module provides basic motion detection in a small package. Compatible with the Arduino and Raspberry Pi
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 iPocket232™ RS232 to Ethernet converter captures the proven reliability of our most popular Remote Access products in a compact, cost-competitive package. Made by Precidia Technologies.
This robot uses custom length sides and 13 inch tires with IG52 82 RPM motors. We have inclued everything to make it ready to run including batteries, chargers, and a controller.
