How to Build Your Own Water Tank Level Sensor...

In this video, I walk you through my DIY smart water tank level sensor build using an ESP32 and a pressure sensor (pressure transducer). It’s solar powered, runs on a Li-ion battery, and uses deep sleep to save power and extend battery life. 📦 Links & files: - ESP32-C6 - https://s.click.aliexpress.com/e/_c3Rv38Nh - Pressure sensor - https://s.click.aliexpress.com/e/_c3fvFGgJ - CN3791 MPPT Solar charger - https://s.click.aliexpress.com/e/_c397IrkL - TPS61023 5V boost converter - https://s.click.aliexpress.com/e/_c4tGmmYX - MAX17048 Fuel gauge - https://s.click.aliexpress.com/e/_c4btO0J9 - Solar Panel - https://s.click.aliexpress.com/e/_c3H6YQ2F - Battery Management System - https://s.click.aliexpress.com/e/_c4T4Nsvv - Waterproof cable gland - https://s.click.aliexpress.com/e/_c4s7yJLD - Waterproof enclosure - https://s.click.aliexpress.com/e/_c3O1XrYj - Instructions, code + full hardware list - https://jrattechworks.com/tank-level-pressure-sensor/ The sensor sends updates via Wi-Fi to Home Assistant using ESPHome, and only wakes up on a schedule to take a reading, then goes straight back to sleep. If you’re on rainwater, living off-grid, or you’re just sick of guessing what’s left in the tank, this is a simple and reliable way to monitor your water level from anywhere. What’s inside the build: • ESP32 • Pressure sensor (reads water pressure to calculate tank level) • Solar + Li-ion battery power system • Deep sleep power saving • Custom case / mounting • ESPHome + Home Assistant integration Got questions or building your own?
