Component Power_Measure

Overview

This example demonstrates how to use the BL0937 power measurement chip to detect electrical parameters such as voltage, current, active power, and energy consumption. It is implemented for ESP32 using FreeRTOS, and shows how to configure and interface with the BL0937 power measurement chip. The example initializes the power measurement system, fetches various parameters, and logs them at regular intervals.

This example supports the BL0937 power measurement chip, which is capable of measuring:

  1. Voltage
  2. Current
  3. Active Power
  4. Energy

The primary goal is to demonstrate how to configure the hardware pins, initialize the power measurement system, and retrieve the data from the chip.

Features

  • Measures voltage , current , active power , and energy .
  • Configures BL0937 power measurement chip.
  • Supports overcurrent, overvoltage, and undervoltage protection.
  • Energy detection is enabled for accurate readings.
  • Regularly fetches power readings every second and logs them.

Hardware Requirements

The example uses the BL0937 power measurement chip. To connect it, the following pins must be configured on the ESP32:

Variable GPIO Pin Chip Pin
BL0937_CF_GPIO GPIO_NUM_3 CF Pin
BL0937_SEL_GPIO GPIO_NUM_4 SEL Pin
BL0937_CF1_GPIO GPIO_NUM_7 CF1 Pin

Make sure that these GPIO pins are correctly connected to the respective pins on the BL0937 chip in your hardware setup.
