HVAC Performance Monitor Kit with ESP32 + BMP280
Build a Solar-Powered Crop Health Dashboard with ESP32 and BMP280
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you assemble a standalone field unit that photographs crop leaves once a day, logs temperature, humidity, and barometric pressure, and stores timestamped data on an SD card—all powered by a solar-charged battery. It turns an ESP32-CAM into an autonomous precision agriculture tool, enabling data-driven decisions on greenhouse HVAC or open-field microclimate tracking.
What You'll Build
A weatherproof monitoring station that captures daily leaf images with the ESP32-CAM, reads environmental conditions from the BMP280 and DHT22, timestamps every record with the DS3231 RTC, and writes everything to a microSD. The LM2596 buck converter and TP4056 charging module manage solar input from a 6V 2W panel to two 18650 cells, giving you a self-sustaining system. The result is a dedicated crop health reporter that runs unattended, helping you detect stress patterns, disease onset, or HVAC setpoint drift.
What You'll Learn
- Integrating ESP32-CAM with multiple I2C sensors and managing image capture sequences
- Implementing solar charging, battery management, and power regulation with 18650 cells and TP4056
- Designing a timestamped data logger that writes BMP280 and DHT22 readings alongside image metadata to an SD card
- Calibrating and interpreting environmental sensor data for agricultural context, such as vapour pressure deficit or leaf wetness proxies

Who This Kit Is For
B.Tech ECE/EEE students working on Smart India Hackathon agriculture challenges will find a complete hardware stack ready for sensor fusion and remote deployment. Research scholars at IITs, NITs, VIT, or BITS Pilani developing precision farming or greenhouse automation can prototype rapidly without sourcing headaches. ATL Tinkering Lab associates and CBSE Class 12 innovators building environmental monitoring projects can scale up from basic Arduino setups to a production-grade IoT logging station.
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 launch the AI companion, which walks you through wiring, firmware upload, and troubleshooting with conversational guidance. You can also send images via WhatsApp for human backup support within a few hours.
Can this kit monitor crops continuously if sunlight is low?
The 2W solar panel charges two 18650 cells; with a full charge the system can run for days without sun. For monsoon-heavy regions, you can place the panel for maximum diffuse light—our AI companion helps calculate duty cycles based on your location.
Is the ESP32-CAM image quality enough for leaf disease analysis?
The 2MP camera captures clear macro shots suitable for visual inspection. Advanced image processing can be done offline after copying the SD card; the AI companion includes a guide on exporting images for ML tools, though on-device analysis is not pre-loaded.
Can I access data remotely instead of reading the SD card?
The stock kit logs locally for simplicity. Adding WiFi or GSM connectivity is a common upgrade—our support team can point you to recommended ESP-NOW or MQTT additions, and the enclosure has spare cable glands for antenna routing.
HVAC — ESP32-CAM photographs crop leaves daily. BMP280 and DHT22 provide environmental context. Stored on SD.
