This is the Allegros ±25A, ±31A, ±12A, ±15A ACS711 Hall effect-based linear current sensor an integrated overcurrent fault output, which provides you a low-resistance ~ 1.2mΩ current route including electrical isolation reach to 100 volts. This model receives a bidirectional
Wiring the i2C INA219 ZERO Drift, Bidirectional Current/Power Monitor with MCU
This is the INA219B breakout module to measure both high side voltage and DC current draw over i2C with 1 percent precision. Current measuring devices such as current panel meter are good only for low side measuring it means that
