Description
Technical Specs
Current stock has RED PCB
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

The sensitivity of these devices vary proportionally with supply voltage(Vcc). If Vcc is other than stated above, Sensitivity can be determined by feeding a known current load to the device and calculate it's corresponding sensitivity(see data sheet). Calibrating these devices on the host microcontroller against a known current load will increase accuracy in most applications.
