They are mechanically simple, offer high operating speed, good performance with very small currents, highly reliable and have long life. The glass tube contains an inert gas (An inert gas is a gas that does not undergo chemical reactions under a set of given conditions) typically Nitrogen or in the case of high voltage it is just a simple vacuum. Types of Reed Switches ----------------------------------, There are 3 basic types of Reed Switches:1. The leads of the switch must be handled carefully to prevent breaking the glass envelope. Connect the LED to the pin 12 of the Arduino. Introducing the Relay Module A relay is an electrically operated switch that can be turned on or off, letting the current go through or not, and can be controlled with low voltages, like the 5V provided by the Arduino pins. Best Robot Kits Kids The Reed devices are electronic or electromechanical components that work using the technology of the reed contacts, realized for the first time by the Bell. Then connect the Reed Switch to the pin number 13 and ground the other end. One of my favorite Mechanical Relays is the Reed Relay. The usage of this Dry-reed relay is quite alike that of common relays. Mouser offers inventory, pricing, & datasheets for 5 VDC 500 mA Reed Relays. The switch may be actuated by a coil, making a reed relay, or by bringing a magnet near the switch. Best Arduino Books You can then take a 12V power supply and run them through the Reed Relay to basically amplify your Arduino signal. Also, the Arduino Pin (to which the Reed Switch is connected) is pulled HIGH with the help of a Pull-up Resistor. Connect the LED to the pin 12 of the Arduino. In the code, Arduino is programmed to always read the status of the Pin to which the Reed Switch is connected to. Reed switches puts your laptop to sleep/hibernation when the lid is closed. These coils often have many thousands of turns of very fine wire. The switch that we are going to use has two parts: the switch itself, that usually comes opened, and the magnet. A simple project-cum-tutorial on Reed Switch is explained here. Connecting Reed Switch to Arduino Now, lets connect the Reed Switch to an Arduino. Best Power Supplies Soldering Stations Lets first test the Reed Switch without an Arduino. It is a bridge between Arduino and high voltage devices. Using the 12V signal, I then use a more robust relay (I often control 110AC or High Amp DC motors) with that 12V signal that we just previously amplified. Best Waveform Generators They are also used in applications which make use of their extremely low leakage of current. The hermetic sealing of a reed switch makes them suitable for use in explosive atmospheres where tiny sparks from conventional switches would constitute a hazard. They keep your washing machine from running when the lid is open7. They require very less operating power and have lower contact capacitance. So that when the current will flow through the coil it will work as a magnet. How to Control a Relay using Raspberry Pi? If you have made any changes to the circuit (like the pins to which the Reed switch and LED are connected to), modify the code accordingly. Electric Lawn Mowers Wear and life are almost entirely dependent on the electrical load's effect on the contacts along with the material of the reed switch. The code is very simple. Compared to armature-based relays, Reed Relays can switch much faster, as the moving parts are small and lightweight (although switch bounce is still present). The module has both digital and analog outputs. I have designed a simple circuit in which the Reed Switch is connected to Arduino as an Input device. For this tutorial we need:- Reed Switch- 220Ω Resistor- 100Ω Resistor- LED- Multi-meter- Battery- Breadboard- Arduino Nano- Magnets and- Few Connecting Cables, Using a multi-meter I am going to show you how a Reed Switch works. If you are familiar with connecting a Push Button with Arduino, then follow the same step for connecting Reed Switch with Arduino. Oscilloscope Kits Beginners Because of this, manufacturers rate life in number of operations rather than hours or years. A Reed Switch has very low resistance when closed, typically as low as 50 milliohms hence a Reed Switch can be said to require zero power to operate it. Once the magnet is pulled away from the switch, the reed switch will go back to its original position. Burglar alarm systems for the doors and windows.2. The following image shows a simple reed switch with its internal connections. Best Python Books Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor. 10. About Relay A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller. The current flowing in the coil operates the Reed Switch. They’re cheap, they’re durable, and in low-current applications, depending on the electrical load, they can last for about a billion actuation.Thanks----------, Thanks again for checking my post. Specifications. Single Pole, Single Throw, Normally Closed [SPST-NC] (normally switched on)3. In the image, the part on the left with wires coming out consists of the Reed Switch whereas the part on the right consists of a Magnet. June 4, 2018 By Administrator Leave a Comment.

Best Gaming Mouse Best Gaming Headsets Reed switches are so pervasive that you’re probably never more than a few feet away from one at any given time. Connecting Reed Switch to Arduino-----Now, lets connect the Reed Switch to an Arduino. They are mechanically simple, offer high operating speed, good performance with very small currents, highly reliable and have long life.Millions of reed relays were used in telephone exchanges in the year 1970s and 1980s.Areas of Application-----------------------------, Just about everywhere you go, you'll find a Reed Switch nearby that’s quietly doing its job. In the thermal cut-offs in electric showers, to stop the water heating to dangerous levels.8. Although most reed switches have two ferromagnetic contacts, some have one contact that's ferromagnetic and one that's non-magnetic, while some like the original Elwood reed switch have three. When you buy this switch, it also comes with 4 screws, so that you can attach it to your door. The following image shows the Reed Switch enclosed in a plastic housing along with a magnet (which is also enclosed in a protective housing). Anemometers with rotating cups have reed switches inside that measure the speed of the wind.10. Now, lets connect the Reed Switch to an Arduino. Related products RELAY OMRON G2R-1A-E-T130 DC24V.
