Passive Infra-Red (PIR) sensor is a pyroelectric devices motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can detect by checking for a high signal on a single I/O pin. Usually used as a security device in a monitored area (such as a room or hall) to detect appearance of human.

Features:

• 5V to 20V operation voltage with <100uA current draw
• Single bit output (digital)
• Delay time adjustable
• Compatible with all types of microcontroller
• Small size makes it easy to conceal
• Plug n Play feature
