Relay Modules for WiFi, USB and Internet

Relay modules are designed to switch high power loads like lights and motors from a connected device that could be a phone, computer or microcontroller.

With on board processors the boards are able to communicate over a number of different protocols including USB, Serial, Bluetooth, TCP/IP , UDP WiFi and Ethernet. This allows control of power equipment over a short range using a wired connection or Bluetooth or over a long range using Ethernet, WiFi and even across the Internet.

Inputs are included on some boards to allow sensors or switches to be read by the relay board and the Intellegent Relay board can even operate autonomously to control pumps, motors or gates based on sensor input.
