ESPCistern: ESP32-C3 WiFi cistern monitor using MS5837 depth and BME280 air reference
Battery powered Wi-Fi cistern level monitor using an ESP32-C3, one submerged MS5837 for water pressure and one external BME280 for atmospheric reference. The MS5837 has a fixed I?C address of 0x76, and the BME280 is set to 0x77 by tying SDO to 3V3, so there is no address conflict. The electronics stay dry on the top side of a pass-through PCB and the MS5837 on the bottom faces the water. The board is bonded through a single hole so the module remains outside and easy to service. USB-C is available for programming, charging and serial logs.
Installation:
Drill one hole, insert and bond the PCB, allow curing, leak test and calibrate at one or two known heights.
Scope and growth:
This is a prototype, simple and testable. It is ready for later additions like a basic web setup page, MQTT or HTTP integration and alerts.
