Description
Multi-part IoT system consisting of an ESP32-C3 display gateway with round GC9A01 touch LCD and an ESP32-S3 LoRa sensor node with TL-136 pressure sensor. The sensor node measures the tank level via pressure sensor and sends the data via LoRa (SX1262) to the gateway. The gateway displays the level on the round display and forwards data via MQTT/WiFi.
