Greenhouse Climate Monitor Kit with Arduino Uno + DHT22
Greenhouse Climate Monitor Kit with Arduino Uno + DHT22 – Build Your Own Indoor Plant Environment Tracker
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a live greenhouse climate station that displays current temperature and humidity on a bright LCD, then adds a visual comfort index bar graph using custom-programmed characters. This kit turns your Arduino Uno into a practical tool for monitoring plant health — perfect for school science projects, balcony gardens, or the Smart India Hackathon.
What You'll Build
You'll construct a standalone monitor that reads DHT11 sensor data and shows temperature (in °C) and relative humidity (%) on a 16x2 LCD screen. A dynamic bar graph made from custom character blocks fills up as conditions move from 'too dry' to 'ideal' to 'too humid' — a real-time comfort index for your greenhouse.
What You'll Learn
- How to wire a DHT11 digital sensor and read temperature/humidity data with Arduino
- Using an I2C backpack to drive a 16x2 LCD with just two wires
- Creating custom characters on an LCD to build a bar graph without any graphics library
- Organizing sensor data into a visual comfort index that updates live

Who This Kit Is For
Perfect for CBSE Class 11-12 students exploring sensor-based projects, B.Tech ECE/EEE first-years at VIT or NIT, and ATL Tinkering Lab facilitators looking for a weather-ready beginner kit. Also great for hobbyists building an indoor greenhouse monitor or a Smart India Hackathon prototype.
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 from the QR code or message us on WhatsApp; it guides you step-by-step for this exact kit, no prior Arduino experience needed.
Can I monitor my actual greenhouse with this kit?
Absolutely. The DHT11 sensor is accurate for indoor and greenhouse use, and the LCD gives instant readings. You can extend with a data logger later.
What does the comfort index bar graph show?
It maps humidity and temperature ranges to a visual bar using custom LCD characters, so you can see at a glance if your plants are in the ideal zone.
Does it run on batteries?
Yes, the included 9V battery snap powers the Arduino Uno standalone, making it portable around your greenhouse.
