Free DIY BYO Power Monitoring Instructions and Software with Watts Volts Amps

WattsVIEW^tm Labjack is a FREE computer program that you can install on your computer to see waveforms of voltage, current, and power. If you want to buy an already made power DC power monitor then click here.

These build your own power monitor plans uses a simple data acquisition device called the LabJACK. Seen as the small red box below. It also uses a current sense resistor and voltage divider set of components that you need to hook up yourself. This is shown below marked with the number .

You can follow the instructions to build this simple resistor circuit.

WattsVIEW™ Screen Shots

When you download and install WattsVIEW, you will see that this screen on your computer showing you 3 waveforms, the first is Voltage (White), then Current (Red), and finally Watts (Green). The image below is showing you voltage, current, and Watts data being displayed real time.

WattsVIEW Free power monitoring software showing wats, volts, and Amps.

This is a shot of the sensor setup screen where you enter in resistor values for the voltage divider and precision current sense resistors you have chosen to put into your design. In this example, R1 has a resistance value of 2,000 Ohms, and R2 has a value of 25 Ohms. This would also be expressed as a 80 to 1 voltage divider.

Download

NOTE: This software is written labview and will install the labview runtime engine version 8.6

You will need to follow these steps:

Download the 60MB WattsVIEW Install zip file
Unzip it / extract it to a folder or desktop
Double click on the setup.exe file
When it is done installing download the zip file containing the labjack U12 drivers for windows
Unzip / extract the U12 zip file into a temp folder or your windows desktop
Double click to run the file you extracted in the step above called U12SetupV121.exe
Wait until the program finishes installing drivers and the LabVIEW runtime engine 6.1
Now plug your labjack into your USB port. The green light should blink briefly and the turn off.
Now launch the WattsVIEW program by going to your START button and clicking on the WattsVIEW icon.
For you to get a free pass key to run this software without any limits, you need to follow the steps below.

This is a free trial version of the WattsVIEW power monitoring program. It gives you 10 free trials. If you want to use this software more than 10 times then you need to contact us for the password.

	Description for schematic above and below	Purchasing Information
TB1	This is where you hook up the thing you are trying to deliver power to, like an AC inverter, a water heater, or television.	Buy Now
TB2	This is what you connect your voltage source to, like your bike generator	Buy Now
TB3	This terminal block is what hooks up to the LabJACK	Buy Now
LabJACK	The LabJACK USB Data acquisition box is what measures your voltage an current. I have bought 7 of these for many different projects, they work great!	Buy Now
R1 R2	This is what is known as a voltage divider. It will lower the voltage down to 1/100 of its value to allow the data acquisition LabJACK unit read the signal with out frying it. WARNING: if you pick resistance values that create too much power dissipation, you could start a fire, or burn your hand when you touch these resistors. If you want recommend resistance values send an email to support@wattsview.com	R1 Buy Now R2 Buy Now
R3	This is what is known as a precision current measurement resistor. If you want to know how this works, click here. If you want recommend resistance values send an email to support@wattsview.com	Buy Now
Software	You can write your own visual basic or C++ or LabVIEW software program to collect data from the LabJACK data acquisition unit. You can use this LabVIEW based program that I wrote called WattsVIEW.

The image below shows you which terminals to connect to your voltage divider and your current sense resistor.
