Fig. 1: Authors’ prototype of Arduino motion sensor automation The relay functions as an intermediary switch, controlling connected devices based on commands from the Arduino. This configuration enables the system to turn on lights when a person enters a room and switch them off after a set per...
Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or deactivates electrical devices in response to human movement, enhancing convenience and energy ...
This image might be helpful - in you can see the gate opener with the cover off, my controller (which at the time was a different Arduino replaced by an Uno) with 3D printed case. The connection point for the relay (in my case the first relay on a seperate 8 relay board also in a...
The Arduino drives the relays through transistors connected to 9-volt supply. Technically the relays are 12-volt relays, but they seem to work with 9 volts. I used one 10A relay, and one 5A relay, just because that's what I had around. Needless to say, 120 volts can be dangerous, ...

I am using a 24v power supply for the solenoid valve. The solenoid valve is working if I directly connect it to a power source. It is also working when I remove the Arduino and only the MOSFET remains in the circuit. I also used a single-pole relay to drive the valve. It was worki...
Please note that the board is no longer offered. It has not been offered for some time now. It's ISA and that and the computers that have ISA are out of date. I now offer an alternative through Jameco Electronics. One is called the Listening Tree and uses an Arduino UNO, a small, ...
Since the relay module is controlled through a digital output, we can connect it directly to the Raspberry Pi, if we want. That way, we don't need the Arduino board. (We wouldn't be able to test-run the application on the local machine either, though.) Checking whether GPIO is ...
With the circuit on the picture, it is possibly to use a cheap 230V->5V/2A power buck module to be added at the end of the normal power cable, providing additional relay controlled power to the lamp(s) as well as the dimming control then -> basically like a Zigbee that can just ...
Since you might want to use more than one actions it is adviseable to use global variables (start with capital letter) for "Server:Port" Like: %OHSERVER:%OHPORT put "CMD" into the Path-field write the itemname and the value into the Attributes-field Like: MeAtHome=ON exit this ac...
