Sous-Vide Temperature Kit v2: Cook & Baby Monitor - Arduino Nano
Precision Sous-Vide & Baby Cry Alert System - Arduino Nano Wireless Kit v2
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 single dashboard that tracks your sous-vide water bath to 0.5�C while instantly alerting you if your baby cries in the next room. This Arduino Nano-based kit lets you build that exact dual-purpose wireless system-perfect for an engineering project that solves two real problems at once. You'll solder two prototype boards, pair NRF24L01 radios, and integrate a temperature probe with a cry-detection microphone, learning wireless communication and audio pattern recognition along the way.
What You'll Build
A transmitter unit (Arduino Nano, DS18B20 waterproof probe, MAX4466 mic amp) and a receiver unit (second Nano, 0.96? OLED, active buzzer). The transmitter reads the sous-vide bath temperature and constantly monitors for cry-like sound patterns. Both data streams travel wirelessly to the receiver, which displays live temperature, logs readings, and sounds the buzzer the moment a cry is detected-so you never miss a moment, even in a noisy kitchen.
What You'll Learn
- Programming NRF24L01 modules for reliable long-range wireless data transfer
- Integrating a DS18B20 one-wire sensor with calibration routines for cooking-grade precision
- Processing real-time audio with the MAX4466 to distinguish baby cries from ambient noise using threshold and pattern analysis
- Multi-board soldering, PCB prototyping, and building an interactive OLED interface with alert buzzer

Who This Kit Is For
Advanced hobbyists and B.Tech ECE/EEE students building IoT final-year or Smart India Hackathon projects. The dual-sensor wireless challenge fits perfectly into IIT/NIT/VIT curricula, ATL Tinkering Labs pushing beyond basics, and CBSE Class 12 students ready to tackle a real-world home automation system with genuine utility. If you've already worked with single Arduino boards and basic sensors, this kit will stretch your skills into wireless networking and audio DSP.
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 inside the box to start a guided troubleshooting session with our AI companion, or message us on WhatsApp for direct engineer support-we'll help you identify wiring, code, or interference issues within hours.
Can the system really handle sous-vide temperature and cry detection at the same time?
Yes. The transmitter unit polls the DS18B20 every second and streams the value; the MAX4466 audio samples are analysed on-board for cry-like patterns. Both types of data packets are sent wirelessly to the receiver without conflict, thanks to the NRF24L01's payload management.
Is the temperature probe safe to immerse in a sous-vide bath?
The DS18B20 probe has a stainless steel body rated for continuous immersion up to 125�C. We include heat-shrink tubing to seal the cable entry and prevent moisture ingress, making it suitable for cooking-grade water bath monitoring.
What real-world range can I expect inside a typical Indian home?
With the supplied capacitor filtering, you'll get stable data through two or three concrete walls-typically 30-50 metres. Placing the receiver at an elevated position can extend this; external antennas can be added for larger homes.
Cooking - MAX4466 detects cry pattern. NRF24L01 alerts parent unit. DS18B20 monitors room temperature.
