Current, Hall and Voltage Sensors

Current, voltage, and Hall effect sensor modules measure electrical parameters in a circuit without requiring the microcontroller to be in the signal path. They provide isolated, accurate readings of current draw and supply voltage for monitoring and protection applications.

The range includes INA219 I2C current and power monitors, ACS712 Hall effect current sensors, voltage divider modules, and bidirectional current measurement breakouts compatible with Arduino and ESP32.

These sensors are used in battery charge monitoring, solar panel power tracking, motor current feedback loops, overcurrent detection, IoT energy monitoring systems, and any Arduino or Raspberry Pi project where measuring power consumption or load current is a requirement.
