ESP32 Ultrasonic Mist Generator Kit with Pressure Sensor & SD Logging
Smart Agriculture Ultrasonic Misting Controller Kit with ESP32, Pressure Monitoring & Event Logging
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
High-value greenhouse crops and nursery operations depend on precise humidity bursts to prevent fungal disease and promote uniform growth. With this kit, you construct a fully autonomous misting controller that pulses an ultrasonic mist maker at exact intervals, confirms nozzle output through an analog pressure sensor, and logs every event to a microSD card with timestamps from a real-time clock.
What You'll Build
An integrated misting station that reads ambient conditions, triggers the ultrasonic oscillator via dual relays, and verifies the resulting pressure pulse using the MPX5010 transducer. The ESP32 orchestrates the cycle, displays runtime data on an OLED, and writes structured logs for later analysis - essentially a portable, open-source alternative to expensive commercial foggers.
What You'll Learn
- Interface the MPX5010 pressure sensor with ESP32's ADC and convert raw readings to kPa for nozzle health monitoring
- Program the DS3231 RTC to schedule misting pulses and wake the system at specific times
- Implement a microSD logging subsystem that records pressure, timestamp, and relay state in CSV format
- Solder the complete circuit on a PCB prototype board, managing power regulation with the LM2596 buck converter

Who This Kit Is For
Agricultural engineering undergraduates at NIT, VIT, and state agricultural universities working on precision farming projects. Also ideal for Smart India Hackathon teams tackling horticulture or mushroom cultivation challenges, B.Tech ECE/EEE students integrating IoT into greenhouse management, and researchers prototyping automated misting in polyhouses.
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?
Your AI companion provides wiring diagrams, code snippets, and troubleshooting directly. A WhatsApp backup line with our support team is included inside the box.
Can this system be used for hydroponic or aquaponic setups?
Absolutely. The pulsed misting and pressure verification work well for root zone humidification in indoor growing systems; you can adjust the cycle intervals in the ESP32 code.
Do I need any additional tools beyond what's in the box?
The kit includes a soldering iron and solder wire. You will need a computer with the Arduino IDE to upload code, and a multimeter for testing is helpful but optional.
What crops benefit most from this misting controller?
Greenhouse capsicum, strawberries, mushroom cultivation, and orchid nurseries respond particularly well to controlled ultrasonic misting because it avoids leaf wetting while maintaining high ambient humidity.
Accessibility - Ultrasonic mist generator pulsed at precise intervals by Arduino. Pressure sensor confirms nozzle output. ESP32 logs all events.
