Greenhouse Climate Monitor Kit with ESP32 + DHT22 v3
Build a Dual-Core Greenhouse Monitor with ESP32 and FreeRTOS
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Greenhouse operators need continuous climate data without the monitoring loop blocking uploads. This kit guides you to build a dual-core monitor where Core 0 captures precise temperature, humidity, and tilt readings from DHT22 and MPU6050, while Core 1 independently publishes that data over WiFi via MQTT — no missed sensor readings even during network delays.
What You'll Build
A fully functional greenhouse climate station with an OLED display showing real-time temperature, humidity, and tilt alerts. The system publishes sensor telemetry to any MQTT broker every few seconds, and Core 1 handles reconnections autonomously. You'll walk away with a project that demonstrates industrial-grade task separation on the ESP32.
What You'll Learn
- Designing and running two independent FreeRTOS tasks on an ESP32
- Interfacing DHT22 temperature/humidity sensor with calibration routines
- Integrating MPU6050 accelerometer for tilt detection and vibration alerts
- Establishing resilient WiFi and MQTT connectivity without blocking sensor reads

Who This Kit Is For
CBSE Class 11–12 students tackling IoT and sensor-based projects, B.Tech ECE/EEE undergraduates learning real-time operating systems, and Smart India Hackathon teams needing a reliable dual-core data logger. This kit is also a perfect fit for ATL Tinkering Lab mentors guiding advanced microcontroller concepts at IIT, NIT, VIT, and BITS campuses.
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?
Open the AI companion via the QR code or send a message on WhatsApp. The assistant is trained on this exact project and can debug wiring, code, and FreeRTOS task conflicts in real time.
Do I need prior FreeRTOS experience?
No. The AI build companion introduces dual-core task creation step-by-step. Basic familiarity with Arduino IDE and C/C++ is recommended.
How can I view greenhouse data remotely?
Core 1 publishes sensor readings to any standard MQTT broker (like Mosquitto or HiveMQ). You can then use a phone dashboard app or Node-RED to monitor the greenhouse from anywhere with an internet connection.
Is the kit suitable for a real greenhouse environment?
The electronic components are indoor-rated. To deploy in a greenhouse, place them inside a protective enclosure (not included) to shield from humidity, dust, and temperature extremes. Core 0 continues logging locally even if WiFi drops.
Greenhouse — Core 0 runs sensor reading loop. Core 1 handles WiFi and MQTT publish independently using FreeRTOS tasks.
