Raspberry Pi Pico W Sous-Vide Temperature Control Kit
Raspberry Pi Pico W Smart Sous-Vide Monitoring and Control Kit
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 cooking a steak to perfection with �0.1�C accuracy while tracking water quality in real time. This kit lets you build a sophisticated sous-vide controller that not only regulates temperature via a heater relay, but also monitors pH and electrical conductivity (TDS) - turning your kitchen into a food-grade lab. All sensor data streams to your phone over MQTT for remote monitoring.
What You'll Build
A fully functional water bath control system with an OLED display. It reads dual waterproof DS18B20 sensors for precise temperature averaging, then switches relays to manage a heater, pump, and aerator. Simultaneously, pH and EC levels are measured, and all data is published to an MQTT dashboard so you can observe cooking progress from your phone or laptop.
What You'll Learn
- Interfacing DS18B20 one-wire temperature sensors and calibrating multi-point readings for �0.1�C accuracy
- Reading analog pH and TDS/EC modules using the Pico W's ADC, applying calibration curves and temperature compensation
- Controlling high-power relays safely with microcontroller logic for 230V appliances like heaters and pumps
- Publishing sensor data to an MQTT broker and building a real-time monitoring dashboard with Node-RED or similar tools

Who This Kit Is For
Advanced B.Tech ECE/EEE students building final-year IoT projects in food tech or precision agriculture, participants in Smart India Hackathon challenges around sustainable cooking, and ATL Tinkering Lab mentors guiding food-science innovations. It also suits culinary professionals and researchers exploring sensor-driven cooking methods.
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?
The AI companion walks you through each wiring step and code upload; if you still need help, our WhatsApp support team typically responds within an hour, referencing your exact kit version.
Is this kit safe to use with real food?
The DS18B20 probes are waterproof, but direct food contact requires food-grade encapsulation. We recommend using the kit as a learning tool in water tests or with probe sleeves; the AI companion includes safe-handling guidelines.
Do I need prior experience with MQTT or networking?
Basic familiarity with the Raspberry Pi Pico and Arduino IDE is assumed. The companion provides step-by-step MQTT broker setup and Node-RED dashboard creation, making it accessible even if you're new to IoT protocols.
Can I expand this to control a real sous-vide immersion circulator?
Yes. The relay module can switch a 230V heater or pump. The AI companion includes wiring diagrams for mains-powered appliances with essential safety precautions like proper earthing and isolation.
Cooking - Pico W reads DS18B20 water temp, DO, pH and EC. Controls heater, pump and aerator relays with MQTT reporting.
