A very simple nanovoltmeter with picovolt resolution. The high resolution is possible by using a chopper, auto correlation, a modified delta-sigma analog to digital converter, a 16 bit PWM with passive five pole RC filter configured in a self nulling loop. All signal processing after the chopper is done in the AC domain with the circuit configured as a nulling amplifier. AC amplifier gain is 10,000,000 and the amplifier is fed into the Arduino ADC. This gives resolution of 100 pV per bit...

Researches have shown that immediate feedback can increase energy saving dramatically. YoMo aims to empower people using low-cost open hardware smart meters in their household. The metering system consists of a coordination unit, a raspberry pi, and several smart meters, arduino boards equipped with communication shields and our self-designed yomo metering shield. The smart meters are attached to household devices and monitor their energy consumption. The gathered data is timestamped...
