Digi International's Rabbit RCM5450W Wi-Fi network module is being used in a thermal solar energy system controller from US-based Heliodyne.

The controller monitors the system, reads the sensors, and signals the pumps when to turn on and off and the RCM5450W connects the controller to the Internet via Wi-Fi.

"We are currently the only American manufacturer to offer remote energy monitoring and control," said Mike Starkey, lead engineer, Heliodyne.

A feature of the RCM5450W is that it incoporates web libraries, an embedded Web server and FCC certifications.

"All that CGI stuff was taken out of our hands through the RabbitWeb libraries and embedded Web server. It was pretty much design a Web site and put in a few variables, and we were up and running. It saved us a lot of time," said Starkey.

The RCM5450W RabbitCore module provides Wi-Fi/802.11b/g functionality.
