Pirelay-V2

PiRelay-V2

PiRelay V2 is developed by SB Components with the potential to control 4 appliances and loads up to 250V AC/ 7 A, 30V DC/ 10A to provide a way to control the high voltage/current devices. It helps the user to enhance the intelligence of the appliances. It comprises an “Optocoupler” that allows the circuit to transmit an electrical signal between two isolated circuits through light energy. Optocoupler helps the user to prevent the high voltages in one part of the circuit from affecting the other part of the circuit which provides safety to the system. It provides a better connection of Pi Relay V2 with the Raspberry Pi that gets enabled from the standardized shield form factor. One can enable the IoT technology of their home appliances using Pi Relay V2 that will make their life efficient.

Hardware Details

• There are a total of 5 led's on the PiRelay-V2 board.

The power led will light up when the board is powered via gpio header. The status/indicator led will light up when the relay1-relay4 is activated.

Installation

Python

• Stack PiRelay-V2 HAT on Raspberry Pi 40 Pin GPIO header.
• Make sure all four jumpers are connected.
• Open Terminal and clone/download the repository by typing below command in terminal:

git clone https://github.com/sbcshop/PiRelay-V2.git

• Your code will be downloaded to '/home/pi' directory. Use 'ls' command to check the list of directories and 'cd' command to enter directory.

cd PiRelay-V2

• 'test.py' is example code for PiRelay-V2. Run test file and play with PiRelay-V2 by running below python command.

python3 test.py

• You can also use any other GPIO of Raspberry Pi by removing the jumpers and connecting the relay pin directly to the Raspberry Pi GPIO header using jumper cables or wire.

GPIO 4 Relay Not working Fix

• Click on Start button >> Preferences >> Raspberry Pi Configuration, Then click on Interfaces Tab and make sure 1-Wire is disabled.
• Click on the OK button then reboot Raspberry pi.
