SEN-11769

Module with 3-axis digital compass, HMC5983, I2C, SPI, RoHS

This module provides precise, galvanically isolated current measurement within a range of ±30 A and voltage up to 480 VRMS, providing RMS, instantaneous, and active, reactive, and apparent power readings. Equipped with an I²C interface, 4-pin JST SH connectors, and 2.54 mm pins, it allows for easy integration with Qwiic, STEMMA QT, and standard microcontrollers. Configuration stored in EEPROM allows for defining address and overload thresholds. The sensor offers three voltage measurement ranges (120 V - default, 240 V, 480 V RMS) and the ability to detect overvoltages. Built-in protection and low conduction resistance ensure safe and accurate measurements. Pololu 5410

Three-axis accelerometer module with MMA8452 system; I2C bus

A compact Hall-effect current sensor that provides accurate DC and AC current measurement within a ±10 A range with galvanic isolation. It features an analog VOUT output with a sensitivity of 200 mV/A and a 150 kHz bandwidth, enabling fast and precise readings in dynamic systems. The module operates over a wide temperature range of -40°C to 125°C, and the low current path resistance (~1.6 mΩ) minimizes energy loss. Its small size and flexible mounting options make it ideal for prototyping, industrial systems, and space-constrained projects. Pololu 5442
