Mini Reed Sensor

DESCRIPTION

The Mini Reed Switch Module activates a switch closure when a magnetic field comes near.

PACKAGE INCLUDES:

Mini Reed Switch Module

KEY FEATURES OF MINI REED SWITCH MODULE:

Outputs logic HIGH or LOW depending on if a magnetic field is near

Built-in 10K pull-up resistor

3.3 and 5V compatible

Reed switches are mechanical switches that are activated by a magnet when the magnetic field pulls the metallic switch contacts together. Real world uses include applications such as home security where a reed switch is placed in proximity to a magnet when a window is closed. If the window is opened, the magnet moves away from the switch that causes it to change states which can then be detected by an MCU.

This module is a SPST switch with NO (Normally Open) contacts until a magnet comes into close proximity to the glass envelope and then the switch contacts are closed. The output is HIGH when the switch is open and is grounded (LOW) when the contacts are closed.
