WiFi Pool Temperature Monitor
Monitor Your Pool’s Temperature Over WiFi – ESP8266 & DS18B20 Kit with Daily Reports and Cold Alerts
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Keep your pool enjoyable without manually checking the water every morning. This kit lets you build a waterproof sensor probe that floats in your pool, connects to your home WiFi, and automatically sends a daily temperature summary plus instant cold alerts to your phone. No more guessing if the water is warm enough for a swim – your own IoT dashboard does the work for you.
What You'll Build
A fully submersible DS18B20 temperature probe wired to an ESP8266 microcontroller, all mounted on a breadboard. The 0.96-inch OLED display shows real-time pool temperature. The ESP8266 connects to your WiFi and, using the pre-loaded sketch, pushes a daily report (e.g., “Today’s pool average: 26.5°C”) to your Telegram or a simple web API. If the water drops below your chosen threshold, it sends an immediate alert so you know it’s too cold for a comfortable dip.
What You'll Learn
- Wiring and calibrating a DS18B20 digital temperature sensor with precise 4.7kΩ pull-up resistor logic
- Programming an ESP8266 NodeMCU using Arduino IDE to read sensor data and manage WiFi connectivity
- Creating automated daily summaries and push notifications via Telegram bot or IFTTT webhooks
- Driving a 0.96-inch OLED display over I2C to show live temperature readings and alert status

Who This Kit Is For
Ideal for CBSE Class 11–12 students building a niche IoT project for their physics or computer science practicals, B.Tech ECE/EEE learners exploring wireless sensor networks, and Smart India Hackathon participants who need a ready-to-demo home automation tilt. ATL Tinkering Lab mentors and hobbyists at NIT, VIT, or BITS Pilani will also find it a solid addition to their smart living portfolio.
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.
What if I get stuck during the build?
Scan the QR code to talk to our AI companion trained on this project, which gives step-by-step debugging tips. If you need a human touch, WhatsApp us – our team typically replies within an hour.
Do I need any soldering skills?
No soldering is needed. The breadboard lets you connect all components with jumper wires. The DS18B20 probe comes with a pre‑attached connector for easy insertion.
How does it send temperature reports to my phone?
We provide ready‑to‑upload Arduino code that links the ESP8266 to your WiFi and sends data via a Telegram bot API. The AI companion walks you through creating a free Telegram bot in minutes.
Can I use this to monitor a fish tank or water storage tank instead of a pool?
Absolutely – the waterproof DS18B20 works in any freshwater environment. The same code and setup apply to fish tanks, aquariums, or overhead tanks to catch freezing or overheating risks.
