Voltage & Current Sensor

Measures bus voltage and current on the same board and calculates power, all reported digitally over I2C so there is no analogue accuracy loss along the way. It measures on the high side, meaning it sits in the positive supply line rather than in the ground return, which is the correct way to monitor a load without disturbing its ground reference. Ideal for battery monitoring, solar projects and finding out what is actually draining a device. Voltage, current and power from one I2C device; High-side measurement leaves the load ground intact; 12-bit resolution with programmable gain; Multiple devices on one bus via address jumpers
