Project description
Summary This ESP32 project monitors DS18B20 temperature sensors across two OneWire buses and sends readings to an external server through a WIZnet W5500 Ethernet interface. The W5500 replaces the earlier Wi-Fi transport and provides the wired TCP/IP path used for HTTP POST telemetry, local web monitoring, configuration, and bus diagnostics. What the Project Does The project is a multi-point temperature monitor built around an ESP32, DS18B20 digital temperature sensors, and a W5500 Ethernet module. The current v2 design reads DS18B20 sensors on two OneWire buses, maps Bus 1 to GPIO 25 and Bus…
