Monitor Your Greenhouse Climate Live with Raspberry Pi 4 & Node-RED 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.

Imagine walking up to your greenhouse and checking live temperature, humidity, air pressure, and light levels on a colourful web dashboard accessible from any phone or laptop in your home network. You won’t be buying a commercial climate computer—you’ll have built it yourself, using a Raspberry Pi, real sensors, and Node-RED’s flow-based programming. This kit gives you every sensor, resistor, and wire needed, so you can focus on learning how modern precision agriculture works and customising the dashboard exactly the way you want.

What You'll Build

You’ll assemble and program a multi-sensor climate monitor that streams real-time data into a Node-RED web dashboard. The dashboard displays live gauges for temperature and humidity from two DHT22 sensors placed at different greenhouse zones, a barometric pressure reading from the BMP280, and light intensity from two LDRs. Historical line charts let you spot trends across hours or days, and you’ll configure simple alerts if any value moves outside an ideal growing range. The final system runs headless on the Pi—no monitor required—and can be expanded with more sensors later.

What You'll Learn

• Wire DHT22, BMP280, and LDR sensors to Raspberry Pi GPIO pins and read their data with Node-RED nodes
• Design a live web dashboard with gauges, charts, and indicators using Node-RED’s Dashboard module
• Manipulate sensor readings with function nodes to calibrate, average, and set threshold triggers
• Set up the Pi as a standalone server so the dashboard is accessible over Wi-Fi without external screen

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate project fits perfectly with CBSE Class 11–12 computer science or B.Tech ECE/EEE curriculum, where students need to demonstrate IoT and web-based data visualisation. It’s also a strong choice for Smart India Hackathon prototyping, ATL Tinkering Lab extensions, or personal exploration by young makers at IIT/NIT/VIT/BITS who want a real-world greenhouse automation project. No soldering is required—the kit uses a pre-soldered GPIO header and jumper wires, so you can set up, tear down, and iterate quickly.

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.
