Overview
Electronic brick of magnetic switch can be connected to digital I/O port to obtain the current status of magnetic switch by reading the current digital signal. Generally speaking, output is high level; when the sensor encounters magnetic objects (such as magnet), output is 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.
3. Sensor is located on the edge of PCB to facilitate detection.
