Hydroponics Nutrient Monitor Kit v2
Build a Live Hydroponics Nutrient Monitor with ESP8266 — Watch Moisture on Your 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.
Grow your hydroponic plants with confidence. This kit lets you build a Wi‑Fi‑enabled monitor that reads soil moisture levels and shows them on a live web dashboard, updating every 10 seconds — no subscription, just your local network. Perfect for budding agri‑tech innovators, school science fairs, or anyone curious about smart farming.
What You'll Build
A portable, breadboard‑based sensor station that uses an ESP8266 to read soil moisture, host a small web server, and serve a real‑time gauge you can view from any phone or laptop on the same Wi‑Fi. Place it next to your hydroponic setup and check moisture at a glance, without ever opening an app.
What You'll Learn
- Interfacing a resistive soil moisture sensor with an ESP8266 NodeMCU
- Writing an Arduino sketch that turns the ESP8266 into a web server
- Reading analog sensor values and converting them to moisture percentages
- Serving a self‑refreshing HTML page that updates every 10 seconds

Who This Kit Is For
Ideal for CBSE Class 11–12 physics or computer science projects, B.Tech ECE/EEE mini‑projects, ATL Tinkering Lab activities, and hobbyists exploring smart agriculture. Even a 5‑year‑old can follow along with adult supervision — all connections are on a breadboard, no soldering required. If you’re preparing for the Smart India Hackathon or a NIT/VIT science exhibition, this kit gives you a solid IoT starting point.
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.

How does the sensor work with hydroponic nutrient solution?
The moisture sensor reads the electrical resistance between its two probes when inserted into the growing medium. In a hydroponic system, you can place it in the root zone or in a sample of the nutrient solution; dry conditions show high resistance, wet conditions low resistance, and the ESP8266 converts that into a readable percentage.
Can I view the moisture readings from my phone?
Yes. As long as your phone is connected to the same Wi‑Fi network as the ESP8266, you can open a browser and enter the device’s IP address. The page auto‑refreshes every 10 seconds, so you always see the latest moisture level.
Do I need any programming experience to build this?
None at all. The included AI build companion gives you the complete code and walks you through every step. You’ll learn the basics as you go, and the sketch is ready to upload right out of the box.
