Greenhouse Climate Monitor Pro Kit with Raspberry Pi 4 + DHT22
Greenhouse Climate Monitor Pro Kit with Raspberry Pi 4 + DHT22 — Build a Phone-Accessible Climate Dashboard
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
With this kit, you'll build a full-stack greenhouse climate monitor that measures temperature and humidity via a DHT22 sensor and controls fans, heaters, or misters using a 4-channel relay module — all managed through a Node-RED dashboard accessible from your phone on local WiFi. No coding marathons or separate part orders: everything arrives in one box.
What You'll Build
A real-time environmental monitoring system for indoor grow areas or terrace greenhouses. The Raspberry Pi 4 reads sensor data, displays it on a customizable dashboard with live gauges and charts, and lets you set thresholds that automatically trigger relays to turn equipment on or off. You'll end up with a professional-grade Node-RED UI running on your local network, no cloud subscription required.
What You'll Learn
- Installing and configuring Node-RED on Raspberry Pi
- Wiring the DHT22 sensor and reading humidity/temperature via GPIO
- Building a dashboard with gauges, charts, and control switches
- Automating relay actions based on sensor thresholds (e.g., fan on if temp > 30°C)

Who This Kit Is For
Ideal for B.Tech ECE/EEE students working on agri-tech projects for Smart India Hackathon or academic mini-projects. Also perfect for CBSE Class 11-12 students exploring IoT with Raspberry Pi in ATL Tinkering Labs. Hobbyists aiming to automate a home or terrace greenhouse will find this kit quickly gets them to a working system without sourcing hassles.
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 open the AI companion for step-by-step guidance, or message us on WhatsApp for direct support from real engineers.
Can I control this greenhouse monitor remotely from outside my home?
The dashboard runs on your local WiFi by default, but you can extend access via a VPN or port forwarding — the AI guide includes clear instructions for both options.
Does this kit require soldering?
No soldering needed. The GPIO header, DHT22, and relay module connect using the provided male-female jumper wires, so you can build on a breadboard or just with jumper cables.
What devices can the relay module control?
The 4-channel relay can switch up to 10A loads at 250V AC or 30V DC, allowing you to automate fans, pumps, grow lights, or heaters in your greenhouse setup.
Greenhouse — Pi 4 Node-RED dashboard controls GPIO relays and reads DHT22. Accessible from phone on local WiFi.
