Reed Switch Sensor Module

Specifications the ky 021 mini magnetic reed switch module consists of a 10kω resistor and a small reed switch actuated by a magnetic field commonly used in mechanical systems as proximity sensors.

Reed switch sensor module.

In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope. Reed switch sensor module consists of three pins i e. Digital switching output 0 and 1 ad 025 reed switch module with bolt holes for easy installation ad 025 reed switch module use a wide voltage lm393 comparator pin connection to board. A reed switch is a switch that needs a magnet in front of it to switch on or off.

Reed switch sensor module. The contacts are usually normally open closing when a magnetic field is present or they may be. For this you need to keep a magnet near the sensor. The module has both digital and analog outputs.

How to use the reed switch sensor module. Vcc gnd and do. 4 pins package included. It consists of a sealed glass envelope where there are two ferrous elastic reeds and is filled with.

Mini reed switch module. A reed switch is a magnetic sensor that is normally open and gets closed when exposed to a magnetic field. Reed switch is a kind of passive electronic switching component with contacts with a simple structure small size and easy to control. In our example turn off the buildin led on pin 13 if the sensor is closed.

A trimmer is used to calibrate the sensitivity of the sensor. Be the first one to review this product. Using the reed switch sensor module with a microcontroller is very easy. Hw 481 colorful auto flash module 28 hw 482 relay module 8 hw 483 push button module 15 hw 484 magnet ring reed switch sensor module 26 hw 485 large sound microphone voice sensor module 7 hw 486 photo resistor sensor module 21 hw 487 light break sensor module.

A reed module is a magnetic sensor that is normally open and get closed when exposed to a magnetic field. Working voltage 3 3v 5v output format. The reed switch is an electrical switch operated by an applied magnetic field it was invented at bell telephone laboratories in 1936 by walter b. The digital out pin is connected to the output pin of the lm393 comparator ic.

Ky 025 reed switch module for arduino is a small electrical switch operated by an applied magnetic field commonly used as proximity sensor. The internal circuit diagram of the reed switch sensor module is given below. 1 x reed switch sensor module. The comparator output signal clean waveform is good driving ability than 15ma.

Email to a friend. As a signal to control the use of magnetic field lines switching devices the reed can be used as a sensor for counting spacing and so on in the security system is mainly used for door sensor window magnetic production but also it is widely used in a variety of communication devices.
