Overview
Electronic brick of PIR sensor can be connected to digital I/O port and used in anti-theft system or to control lights in the staircase of buildings. When sensor detects the infrared signals of human body, it outputs high level; generally speaking, it outputs low level.
Features
1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.
