Relays are electronic components that work like light switches, opening or closing with an electrical signal. By connecting relays to a Wi-Fi enabled microcontroller, you can build a connected switch that can be controlled from a web browser on any device connected to the same Wi-Fi network—for just a few dollars. Relays can free you from the work of physically turning devices on or off when you need to do so remotely. The WiFi mains relay is designed to respond to electrical signals to open and close, and can be used to control the power to almost any device. This means that relays can be combined with inputs such as motion sensors or microcontrollers to make them respond to the environment or commands.
The WiFi mains relay controller is designed for industrial use and has a long service history and proven reliability record. There are also WiFi mains Relay controllers with cloud control capabilities on the market. You can use your own custom code or use our special firmware with IFTTT to control these controllers from the Particle Cloud. Cloud controlled Relay Controllers enable you to easily control WiFi mains Relays from anywhere in the world. The WiFi mains Relay board comes equipped with I2C expansion ports, unlocking limitless sensor monitoring applications. Custom firmware is often required for Relay Controllers, but the industrial Relay Controller is ready to use out of the box on local Wi-Fi networks.
The WiFi mains relay controller provides a popular solution for wireless relay control. Relay control is achieved by sending TCP/IP commands over a LAN to control the on-board relay. The Wi-Fi Relay Controller is cross-platform compatible because all operating systems can send and receive TCP/IP data. Wi-Fi is a popular choice for Android and IoS operating systems, as the Wi-Fi Relay Controller can be controlled in standardized ways.
The on-board ADC (Analog to Digital Converter) can be used for sensor monitoring applications over Wi-Fi. Using the on-board ADC input, the WiFi mains Relay can read voltage sensors, temperature sensors, thermistors, and more over Wi-Fi. When connected to simple switches and buttons, the ADC inputs can be repurposed for manual control of the on-board relay. Simply connect a button to the ADC input and remap the ADC input to turn off all relays, simulating an emergency stop switch. Inputs can be used to blink relays, turn relays on or off, or change the state of the on-board Relays.
