Live Tide Gauge Dashboard – Build a Wi‑Fi Water Level Monitor That Displays Charts in Any Browser

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Create your own automated water level monitoring station. An ultrasonic sensor sealed in a waterproof tube takes a reading every 60 seconds, then the ESP8266 serves a locally hosted web page with a live-updating tide chart. Perfect for tracking estuaries, wells, sumps, or any body of water where understanding the rise and fall matters. No subscriptions, no cloud dependencies – the dashboard lives on the device itself, accessible from any phone or laptop on the same Wi‑Fi.

What You'll Build

You will assemble a robust sensor head that can be partially submerged, connect it to the NodeMCU, and flash the firmware that turns raw ultrasonic pulses into a graphical tide log. The OLED shows instant readings; the microSD module stores every timestamped record. But the centerpiece is the ESP8266’s web server – it generates an HTML page with a real‑time line chart, so you can watch the water level change minute by minute from your couch or classroom.

What You'll Learn

• Interface an HC‑SR04 ultrasonic sensor in a waterproof setup and calibrate distance-to-water-level conversion
• Build a non‑blocking web server on ESP8266 that updates a client‑side chart using JavaScript and AJAX
• Use a DS3231 RTC to tag each measurement with an accurate timestamp and log the data to a microSD card
• Combine hardware components – resistors, capacitors, breadboard – to create a stable, noise‑free sensor circuit

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for CBSE Class 12 electronics students who need a capstone project that demonstrates IoT and data visualisation. B.Tech ECE/EEE first-years will appreciate the hands‑on introduction to web‑based dashboards without requiring a Raspberry Pi. It also serves Smart India Hackathon teams, ATL Tinkering Labs, and IIT/NIT/BITS makers who want a reliable, self‑contained water monitoring prototype in a single box.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
