Hardware sensors monitor utilizes sensor chips on smart motherboards to track
system, CPU and VPU temperatures, voltages and cooling fans.
By quickly catching an overheated computer, you can prevent disasters such
as system instability or damage. The program is resource friendly, resides
quietly in the system tray, and continually monitors the various parameters. By clicking
its icon, you'll view real time values for each component.

An easy to use Windows program that allows the monitoring of laptop computer batteries and uninterruptible power supplies (UPS). Graphically see the battery charge / discharge rate, diagnose problem battery cells, compare your batteries performance with expected discharge rates and see the status of each individual battery pack (when multiple batteries are in use). More than 20 statistics are provided including voltage, chemistry and capacity.

Plus full colour printing showing your own chosen values, copy and paste to make custom teacher handouts or students course work, modify or add.

Coding and decoding of color coded resistors and capacitors with 4 and 5 bands.
Colors are decoded to value, tolerance and maximum working voltage (capacitors) of the component. Inversely, entering value and tolerance displays the color codings. Option to compute the resulting value of a series or parallel resistor or capacitor network with 2 or 3 components. No installation required.

Ever wondered how much money that light left on all night is costing you in bills? Or that stereo that just seems to never stop playing from the kids room? How about which of your household appliances contribute the most to your monthly energy bills? Our Watt-U-Use home energy calculator can show you the costs of running a variety of household appliances, so you can budget for your next utility bills.

The program for controlling a UPS allows you to considerably extend and supplement capabilities of your uninterruptible power source, to control and adjust an electric power supply in the office and at home. The program is simple in installation and in use.
