Pi Pico W Aquaponics Kit: Monitor pH, EC, Temp & Relay Control
Pi Pico W Aquaponics Controller Kit - Build a Smart Water Quality Monitoring and Control System
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a self-regulating aquaponics system where the water is constantly monitored for temperature, pH, and nutrient load, and critical equipment like heaters and pumps are automatically controlled. With the Pi Pico W Aquaponics Controller Kit, you'll build exactly that - an IoT-enabled device that keeps your plants and fish thriving while you track everything from your phone via MQTT.
What You'll Build
A complete, connected aquaponics controller that reads two DS18B20 waterproof temperature sensors, an analog pH probe, and a TDS/EC meter. The Pico W processes these readings, displays them on a crisp 0.96-inch OLED, and uses a 4-channel relay module to turn a heater on or off based on temperature thresholds, manage a water pump cycle, and operate an aerator. All data is reported wirelessly via MQTT, giving you real-time visibility into your system from anywhere.
What You'll Learn
- Interfacing multiple analog and digital sensors with the Raspberry Pi Pico W using MicroPython
- Calibrating pH and EC probes for precise water quality measurements
- Programming relay logic to automate heaters, pumps, and aerators based on sensor feedback
- Publishing sensor data and receiving commands over MQTT for IoT remote monitoring

Who This Kit Is For
This advanced kit is designed for B.Tech ECE/EEE students tackling final-year projects, Smart India Hackathon teams prototyping IoT solutions for precision agriculture, and IIT/NIT/VIT/BITS students exploring connected sensor networks. If you already have basic electronics and Python experience and want to move into real-world automation, this project is your perfect launchpad.
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 start a chat with the AI companion trained on this kit, or send a message on WhatsApp for direct human support from our team.
Do I need to calibrate the pH and EC sensors? How?
Yes, both sensors require calibration before use. The AI companion provides step-by-step calibration routines using standard buffer solutions (not included) and will walk you through adjusting the code offsets.
Can I use this kit to monitor a hydroponics system instead of aquaponics?
Absolutely. The same sensors and relay logic apply to hydroponics. You may simply skip the aerator channel or repurpose it for an additional pump or light; the code is fully configurable.
What coding knowledge is needed?
You should be comfortable with basic MicroPython and the Thonny IDE. The AI companion explains every line of the starter script, so even intermediate coders can follow along and customise it.
Pico W reads DS18B20 water temp, DO, pH and EC. Controls heater, pump and aerator relays with MQTT reporting.
