CMIS (Current Monitor IoT Sensors), SDK Kit is based on an Espressif ESP32 WROOM and the board is designed to monitor four fully isolated DC currents up to 100A. An I2C reversible 2.54mm header is provided in the middle of the board, which will allow an OLED display (such as a SSD1306 I2C), to be […]
CMIS (Current Monitor IoT Sensors), SDK Kit is based on an Espressif ESP32 WROOM and uses the internal ADC for reading sensor values. Other useful advanced ESP32 ADC functions for future experimenting are: analogReadResolution(resolution): set the sample bits and resolution. It can be a value between 9 (0 – 511) and 12 bits (0 – […]
CMIS (Current Monitor IoT Sensors), SDK Kit is based on an Espressif ESP32 WROOM and the board has four AC/DC ACS758 100A (ACS758LCB-100B-PFF-T), Hall Effect based, Linear Current Sensors. These bi-directional current sensors will read +/- 100A and have a sensitivity of typically 20mV/A. The example code below will enable you to calibrate the […]
