The CS-100A is a Hall effect current sensor board capable of measuring Bi-directional DC current flow. This sensor can be used in AC and DC systems requiring isolation from the measured circuit and has low insertion loss and more connection options compared to conventional resistive current shunts.

The Hall-effect chip senses the magnetic field generated by the current flowing through the sensors legs, which in turn outputs an analog voltage proportional to the current it senses. The sensitivity of the device is factory laser trimmed for precision and accuracy with a wide temperature range.

The Analog output of the sensor may be connected directly to an Analog Digital Converter or ADC port of most micro controllers and read easily by a few lines of code, it can also be configured so that an Op-Amp/Comparator monitors the voltage output for current limiting or overload indication.

NOTE: Measuring AC currents would require RMS-DC conversion for it to be read correctly by a micro-controller's ADC and will be uni-directional only.

Features:
  • Measures Bi-directional DC and uni-directional AC currents
  • Low noise, Low loss Monolithic Hall IC
  • Fast and accurate analog output
  • High isolation from measured circuit
  • May be used as High-side or Low-Side sensing
  • 3V to 5V single supply operation
  • Measured circuit up to 300V AC/DC
  • High capacity stitched copper pads
  • Analog output proportional to measured current
  • Flexible connection and mounting options
  • Easy to deploy with most uController systems

Applications:
  • Battery Chargers and Power supplies
  • High current RC and Robotic battery systems
  • Motor Control and Load detection
  • Solar / Wind powered systems
  • Automotive audio equipment
  • Telecom Power supplies
  • Welding machines
  • 2-way radio equipment
  • Power management systems
  • RV and other recreational vehicle battery systems
