Switch a light on/off using your cell phone!
A "normal" style relay to switch a single "data" line to turn on/off.
Perfect for RaspberryPi or Aduino projects. You need 5v to power the relay coil. The input (IN) requires just a few milliamps at anywhere between 2.5v and 12v. You can even use the same voltage you are powering the coil from.
· Low cost way to control larger voltages and currents.
· No soldering required
· Supports any microcontroller
· On-board switching transistor.
· Easy 1 wire drive. High for on, low for off.
· Mains rated relay.
Pinouts (from the left)
A1 - contact 1 (normally open, applies to all models)
A2 - contact 2 (normally closed, only on 6 pin relays).
COM - common
Raspberry PI Relay switch example which will switch the relay on and off at 1 second intervals:
Example Python code for Raspberry Pi will switch pin 7 on:
import RPi.GPIO as GPIO
