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.
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 H8054 PIR motion detection module provides basic motion detection in a small package. Compatible with the Arduino and Raspberry Pi
After building many custom WiFi HD2 robots, we have combined the most common requests and come up with this standard WiFi HD2 robot.
This robot is a prebuilt 2WD All Terrain Robot (ATR) designed and fabricated in North Carolina USA. This robot supports our IG42 planetary gear motors.
