Greenhouse Climate Monitor Kit with ESP32 + DHT22 v10
ESP32 Greenhouse Climate Monitor Kit with OPC-UA Server and SCADA Integration
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create an industrial-grade greenhouse monitoring node where dual-zone temperature, humidity, barometric pressure, and current draw are exposed as addressable objects via an OPC-UA server running on the ESP32. SCADA systems like Ignition, WinCC, or open-source platforms can discover each sensor and log values without custom middleware — exactly the architecture used in modern precision agriculture and factory automation.
What You'll Build
You will assemble and program an ESP32-based device that reads two DHT22 sensors placed in separate greenhouse zones, a BMP280 for atmospheric pressure, and an ACS712 current sensor for power monitoring. The ESP32 runs a full OPC-UA server stack, publishing each physical quantity as a structured data node. The completed build fits inside a DIN-rail enclosure, ready to be mounted alongside industrial control gear and connected to any standard SCADA client over Wi-Fi.
What You'll Learn
- Implement an OPC-UA server on ESP32 using open-source libraries and expose sensor data as typed addressable nodes
- Interface multiple I2C and analog sensors simultaneously while managing 5V power distribution and signal conditioning
- Fabricate and enclose a DIN-rail-mountable sensor node with proper PCB prototyping and cable management
- Connect an ESP32 sensor node to SCADA software for real-time monitoring, alarm configuration, and HMI design

Who This Kit Is For
B.Tech ECE/EEE students building industrial IoT prototypes, Smart India Hackathon teams tackling precision agriculture or smart factory themes, ATL Tinkering Lab instructors introducing SCADA concepts, CBSE Class 11-12 students exploring embedded systems and communication protocols, and hobbyists looking to bridge the maker-to-industry gap will find this kit a focused, hands-on learning experience.
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 on the box to launch the AI companion that knows every step of this greenhouse monitor build. You can also reach out over WhatsApp for real-time guidance from our team.
What is OPC-UA and why is it used in a greenhouse?
OPC-UA is an industrial machine-to-machine protocol that structures sensor data as hierarchical addressable objects. In a greenhouse, it lets SCADA systems discover temperature, humidity, and pressure nodes automatically, enabling centralized control without custom coding for each sensor.
Can I connect this to SCADA software other than Ignition?
Yes. Because the kit implements the standard OPC-UA protocol, it works with any OPC-UA-compatible client such as WinCC, Node-RED with OPC-UA nodes, or open62541-based tools. The AI companion includes setup examples for multiple platforms.
Do I need prior experience with soldering and ESP32?
Basic soldering skills are helpful — a soldering iron and solder wire are included. The AI companion walks you through each connection, and the ESP32 firmware uses Arduino IDE with pre-configured libraries, making it accessible even if you are new to embedded development.
Greenhouse — ESP32 implements OPC-UA server exposing sensor nodes as addressable objects for industrial SCADA.
