Trying to do that with hardwired logic will be next to impossible in a house. I have 21 x 4 gang switches in the house and have programmed for example that all the bottom switches (ie 4th) will either switch the security lights on or off from anywhere in the house, or by remote or via the alarm system using XOR logic.

This is very flexible as I can virtually change the switching logic on the fly from anywhere (where I have the software needed to program the unit) The red wires on the right is the 220V going to the light circuits.Īll light switches operate on 24v and I program the switch to light relationship with the Siemens LOGO.

The NAS is also used for storage of 16 channel CCTV data (CP PLUS Krypto series with 1.5tb local storage)Īll the light switches come in on the left hand side panel, going through Phoenix connectors to either a relay (24v /220V) or to the PLC.

I am using Plex server on a 16tb QNAP NAS, together with a 24tb Drobo Pro storage unit. On the left side panel is a 3G router, an 8 port gigabit router for wifi, Internet and media streaming through the house.

I have tried to use the Raspberry Pi with pywws for capturing and reporting but are still useless at Linux, so it is now connected to a Asus Notebook EEE-PC running Windows 7 and Cumulus for the reporting and capturing of the weather data. In the middle next to irrigation controller is my weather station (reports rain, temperature, humidity, wind direction and speed on various websites and Twitter). Middle right you have a irrigation control system (Orbit 9 channel) which will eventually be replaced with a Arduino Mega as it needs to cater for the rainwater harvesting and grey water recovery systems as well as the aquaponic hothouse (being constructed presently) All the control logic for the lights, borehole pump,water tank level control and pressure pump etc takes place here. The PLC is a Siemens LOGO (0ba7) with Ethernet and one expansion unit giving me 16 digital inputs, 2? analog inputs and 12 relay outputs. There is also a 220V relay below the main circuit breakers for the day/night switch to control the security lights etc. They are really useful and incredibly cheap for their functionality (R170 here in South Africa, or about £10)

Slightly lower on the top right I have three x 2 wireless relays (12v on the coils, 220V 5A on the relay contacts, used normally for activating security alarms, gates etc) that I use to activate lights, water solenoids or anything else for that matter. On the top left I have a 500W ATX power supply giving me a cheap, high amperage, well regulated 3v, 5v and 12v supply for the Arduino, CCTV cameras and Raspberry Pi (not yet in the pictures)

In the top middle I have a 24v power supply for the PLC and just below that a 24v transformer and rectifier to supply DC power to the relay coils. On the top right I have 220V input going through the main circuit breakers, before going to a few distribution bars (white horizontal thingies) for supply to the lights etc I wish to control either via PLC (middle left) or relays (row below PLC) In the below article, we turn on/off a light bulb when LDR detects light.

I will try and explain as best I can, feel free to ask if it is unclear. In this tutorial, we will learn how to use and interface relay module with Arduino. In the case of lightning protection, it is most appropriate to use some additional devices to prevent the discharge from reaching the devices connected to the electrical network.Not as in a formal written description. But there are also other concerns, such as lightning strikes, which cause the electrical network to have a very high over voltage, so the relay can have a low insulation and let this discharge pass from the contact side to the coil side. Because in AC and Arduino loads, one usually wants to know about the safety of insulation, so as not to be affected by an electric shock. On security, it needs to be clearer in what aspect you refer. But incandescent lamps also have a low resistance when it is cold, so it would be interesting to consider this, to avoid premature wear of the relay contacts. For this reason, some modules are already manufactured with optocouplers.Īssuming it is incandescent, and that is 98mA for each lamp, then it would be possible to use a relay for up to 100 lamps. The relay usually already has galvanic insulation between the contacts and the coil, but to improve noise insulation it is also common to use optocouplers. These relays are widely used with AC loads.
