Reed Switch
A reed switch sensor module is a sensor that closes the circuit in the presence of a magnetic field. Reed sensors can be used in many applications where contactless on/off is required. However, reed switches can be fragile to use directly, hence this module can make it easier to handle and mount the sensor in various applications.
This module can be applied in Program-controlled switches, copiers, washing machines, refrigerators, cameras, Disinfection cabinet, door, window magnetic, electromagnetic relays, electronic weighing, level meter, gas meter, water meter and so on.
Reed Switch Sensor Module consists of three pins i.e. VCC, GND, and DO. The digital out pin is connected to the output pin of the LM393 comparator IC. Using the Reed Switch sensor module with a microcontroller is very easy. Connect the Digital Output pin of the module to the Digital pin of Microcontroller. Connect VCC and GND pins to 5V and GND pins of Microcontroller. When the Reed Switch sensor detects the magnetic field, it closes the circuit and the digital pin of the module that is connected to the LM393 IC goes high.
Applications:
- Photocopiers
- Washing machines,
- Refrigerators
- Door Magnets
- Electromagnetic Relays, Electronic Weighing devices, Level Meters, etc.
