About Watmonitor

Watmonitor is a universal web interface designed to efficiently store water level data collected from IoT 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, but is suitable also for industrial-like solutions. Accessible on both PC and smartphones (Android and iOS), Watmonitor offers seamless compatibility with various sensors without interfering with their functionality. The sensor node is capable of transmitting the differential water level or the actual water level measurement from the bottom of the well. System is powered by PHP, HTML5, Bootstrap and MySQL database and more libraries, such as JustGage (Raphaël), ApexCharts.js, highlight.js.

Key features:

  • Real-time Monitoring: View accurate water level and volume data
  • Cross-platform Accessibility: Available on desktop and mobile devices
  • Sensor Agnostic: Compatible with any sensor or industrial monitoring system
  • Usage Scenarios

    Ideal for continuous water monitoring in wells, tanks, sumps, lakes, ponds, rivers, reservoirs, and sewage systems.

    Supported Sensor Types

    Watmonitor supports a wide range of sensor technologies, including: ultrasonic, optical, laser, radar, Capacitive, etc.

    Demo node

    For those exploring open-source solutions, Watmonitor provides example source codes compatible with popular platforms such as ESP32 (WROOM-32, S3, C3, C5, C6) from Espressif Systems. These examples demonstrate the use of ultrasonic distance sensors with Trigger and Echo signals (e.g., RCW-0001, URM [DFrobot], IOE-SR0X, HC-SR0X, JSN-SR04T, HY-SRF0X, DYP-MEXXX, Parallax PING™).

    Additional functions:
  • Multiple Operating Modes: Support for OTA (Over-The-Air) updates, ULP (Ultra Low Power) mode
  • ESP32 Connectivity: Optional WiFi, up to 802.11ax / PHY Ethernet via RMII
  • Advanced Core and OS capabilities: Arduino Core / Espressif's IoT Development Framework (ESP-IDF) with FreeRTOS support
  • QR code scanner

    Streamline monitoring in multi-sensor installations with Watmonitor’s QR code scanning feature. Easily retrieve data for any sensor node by scanning its assigned QR code using a smartphone. This eliminates the need to know the specific Watmonitor interface address, offering a quick, reliable way to access the most recent data from any sensor node.

    Frequently Asked Questions

    The most asked question from the community answered below

    Do I need webhosting to run Watmonitor by myself?

    Yes, you will need local or internet webhosting. To execute PHP scripts of Watmonitor, you will need to have Apache / NGINX installed on your server. Make sure, you are using PHP in version 5.6 up to 7. For PHP version 8, system is NOT compatible.

    Is it hard to configure the webapplication to make it working?

    A step-by-step guide in .pdf format simplifies setup for all users. It covers importing the .sql file into MySQL, configuring connect.php with database credentials, HTTP Auth data, and the device token.

    Will Watmonitor automatically generate source code for my hardware?

    Watmonitor will automatically generate sketches for ESP32's WiFi or PHY Ethernet connection and supported ultrasonic sensors. It will automatically add MCU token into the sketch, it will calculate trace to the target PHP file and will automatically add your domain (for instance localhost will not work! You need to have it opened using IP protocol / domain name). Root CA certificate (in case of HTTPS connection) is NOT changed, so you will need to keep an eye on that and add it yourself into the sketch for ESP32.

    Are there more source codes available except these directly in the Watmonitor app?

    There are different source codes on Github compatible with Watmonitor interface. Created for Arduino + Ethernet (ENC or Wiznet series), ESP8266 or ESP32 and more transmission technologies such as LoRaWAN, Sigfox IoT. You can open them using button "Sensor node examples" on the top of this page.

    What language options are included in the Watmonitor webapp?

    Watmonitor webapp includes full language translations to English, German, Russian, Spanish, French and Slovak

    Can I log data into other system from Watmonitor?

    Yes, there is JSON output provided from the web interface of Watmonitor that allows you to parse these data and use them in your system (Loxone, Grafana, Kibana, Domoticz, Node-RED, Home Assistant, Thingsboard...). Data provided from the system are the latest data of water level, water volume and time of record written into the database.
