5 Channel Current Transducer Sensor Board
This 5 Channel Current sensor board can measure current AC or DC or PWM
(up to 333kHz). It puts out a signal that is directly
proportional to the current being monitored. Take a look
at this graph to see how the sensor behaves.
In the above chart shows
the output voltage of the sensor on the horizontal axis which is
what you get when you measure the sensor output. The vertical
axis shows the corresponding current measured flowing through your
wire of your sensor.
Note: The most
common question is about monitoring AC. If the current being
monitored is an AC current, then the sensor will put out an AC
Applications for this 5 Channel Current Monitoring Board include monitoring alternative energy, Industrial
current monitoring, and for the home hobbyist who has projects
brewing in the garage.
This hall effect current transducer board is easy to use with a data acquisition
system such as "LabVIEW" or LabJACK USB data
logger. It can also be used with a simple hand held volt meter or
oscilloscope. This 5 Channel hall effect board can be mounted easily
into an electrical enclosure combiner box to monitor your solar
panels and wind turbines.
It also is great for laboratory research and development
applications. There are 5 separate current sensors that output 5
independent signals. Each signal has its own offset and gain setting
that you can adjust to your liking. The output terminals on this
board connect easily to data loggers or data acquisition equipment
made by companies like Tektronix, National Instruments LabVIEW, or
You can monitor between -72 to 72 Amps of current, AC or DC. When
the gain is at it's minimal setting, you will see about 36mV output
for every Amp of current detected by the sensor. If your signal is
too weak, then simply loop your wire through the sensor 10 times to
increase the signal strength by 10x. Or simply adjust the gain
adjustment to its maximum value of 10 X. The output range of this
board is about -7 Volts to +7 Volts. When monitoring AC current,
then the output from this sensor will be an AC signal with a
response time of 3 µ sec. The product is firmly mounted on a 1/8"
aluminum plate that has 4 mounting screws.
