Reed Switch Sensor Module

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.

Reed switch sensor module.

How to use the reed switch sensor module. A reed switch is a magnetic sensor that is normally open and gets closed when exposed to a magnetic field. Be the first one to review this product. The module includes a 10 k ohm resistor so no additional parts needed.

Ky 025 reed switch module for arduino is a small electrical switch operated by an applied magnetic field commonly used as proximity sensor. Using the reed switch sensor module with a microcontroller is very easy. The module has both digital and analog outputs. The magnetic read switch module is dry reed short is a kind of passive electronic switch.

1 x reed switch sensor module. A reed switch is a switch that needs a magnet in front of it to switch on or off. Vcc gnd and do. The contacts are usually normally open closing when a magnetic field is present or they may be.

Reed switch sensor module consists of three pins i e. The digital out pin is connected to the output pin of the lm393 comparator ic. A trimmer is used to calibrate the sensitivity of the sensor. It consists of a sealed glass envelope where there are two ferrous elastic reeds and is filled with.

Mini reed switch module. In our example turn off the buildin led on pin 13 if the sensor is closed. 4 pins package included. 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.

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. Reed switch sensor module. Reed switch is a kind of passive electronic switching component with contacts with a simple structure small size and easy to control. 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.

For this you need to keep a magnet near the sensor. The comparator output signal clean waveform is good driving ability than 15ma. The internal circuit diagram of the reed switch sensor module is given below. Email to a friend.

A reed module is a magnetic sensor that is normally open and get closed when exposed to a magnetic field. In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope.
