A Home Assistant Lovelace card that displays real-time river stage, flow, and forecast data from the NOAA NWPS API. Includes a live hydrograph with observed and forecast lines, flood threshold indicators, and impact statements for any NWPS gauge ID.

An Arduino-based water level monitoring system with control via web and mobile apps. Uses ultrasonic and TDS sensors for monitoring.

ESP-NOW Water Level Monitoring System A wireless water tank monitoring solution using ESP8266 boards and ESP-NOW protocol. It measures water levels with an ultrasonic sensor, displays data on an LCD, triggers alarms, and supports OTA updates—no Wi-Fi router needed.

Watmonitor is a universal web interface designed to efficiently store water level data collected from sensor nodes into a centralized database. It empowers users to monitor real-time water level and volume measurements of their water wells, tanks, or other water sources directly through its user-friendly web interface.

Web-based application to monitor river levels, using USGS real-time data

HydroSnap is a mobile application that leverages image processing and AI/ML to monitor river water levels in real time. The app ensures secure data collection, cloud-based storage, and instant alerts, helping communities and authorities with early flood detection, disaster management, and sustainable water resource monitoring.

Smart geyser safety system using STM32, P43 water level sensor, and DS18B20 temperature sensor to prevent dry run and overheating. Real-time monitoring and alerts are enabled via ESP32 and Firebase dashboard.

Display live river, lake, and reservoir gauge data in Home Assistant with this custom Lovelace card for monitoring stage, flow, and hydrograph trends.
