ISURLOG: Industrial IoT Datalogger (Open Source)

The ISURLOG datalogger is a highly versatile ESP32-based device that integrates multiple functionalities for data acquisition and logging in diverse environments. It is a complete and efficient solution for monitoring industrial signals (4-20mA, Modbus RS485, PT100) with advanced connectivity (NB-IoT/LoRaWAN, Wi-Fi, and Bluetooth). This datalogger runs on an optimized MicroPython firmware for low power consumption (20µA in sleep mode), making it ideal for battery-powered applications.
