HC-SR501 Adjustable PIR Motion Detector

Description:

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.

Applications:

Basic motion detection.

Features and Specifications:

Operating Voltage: 4.5V - 20V
TTL Level Output: 3.3V
Delay Time: 5-200ms (adjustable)
Dimension: 32mm x 24mm
