With The Unitronics Controller


Monitor fuel level and temperature and more via the internet with the House Minder's small but powerful Unitronics Controller

Fuel level data and and building temperature are sent to the Unitronics controller via individual sensors, which the contoller communicates over its Ethernet network interface. The monitoring interface for the Unitronics Controller is its built-in website server. Your computer then accesses the server and becomes the "gauge" which can then be read from anywhere on the internet. Here's a sample screen shot:

Plus, there's so much more this product can do. In addition to monitoring fuel level and temperature, the Houseminder with Unitronics can monitor just about any parameter you choose. Unitronics can also be used for data-logging and remote control. Need to store data over time? Need to turn on/off a water main or light? Unitronics can meet all your home automation needs.

The Unitronics Controller is a palm-sized PLC with a built-in Operator Panel. The panel offers a graphic display screen and keypad so you can also monitor parameters locally. The Graphic HMI display screen can show images, text, and graphs according to real-time parameters. It can also display graphs based on historical values, to reflect trends of recorded data.
