If you're looking for a device that is capable of measuring and monitoring voltage up to 24V and current up to 5A, look no further. PWR Meter 2 Click board™ is an ideal solution for you.
This device allows to build power monitoring device with a reasonably low count of elements: A current sensing resistor connected to one channel with the voltage divider connected to the second channel is all that it is required to perform an accurate power measurement.
The product is equipped with the MCP3910, an integrated two-channel analog front-end (AFE) device from Microchip. This IC is composed of several sections, aimed at accurate capturing of the input voltage. Two sigma-delta input A/D converters used with the internal reference voltage of 1.2V with very low thermal drift, reducing the measurement noise at a minimum, yielding Signal to Noise ratio (SNR) up to 96dB.
