Greenhouse Climate Monitor Advanced Kit with ESP32 + DHT22
Greenhouse Climate Monitor Kit with ESP32 & DHT22 — 3-Month Battery IoT Project
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you build a wireless greenhouse climate monitor that wakes up every 15 minutes, measures temperature and humidity with a DHT22 sensor, sends the data to ThingSpeak, and then returns to deep sleep — all running for 3 months on a single LiPo battery. Perfect for young makers learning IoT and automation, and a great addition to any school science project or home gardening setup.
What You'll Build
A compact, battery-powered IoT weather station that you can place inside a greenhouse or plant bed. You’ll assemble the circuit on a breadboard, flash the ESP32 with the provided code, and see real-time sensor data appear on your ThingSpeak channel. The device sleeps between readings, so a 2000mAh LiPo lasts an entire season.
What You'll Learn
- ESP32 deep sleep wake-up timing and power saving
- Interfacing DHT22 sensor and reading digital humidity/temperature
- Sending data to ThingSpeak IoT platform over WiFi
- Managing LiPo battery charging with TP4056 and voltage regulation

Who This Kit Is For
Young learners in India: CBSE Class 11–12 students exploring IoT, ATL Tinkering Lab participants, and first-year B.Tech ECE/EEE students. Also a fantastic Smart India Hackathon prototyping tool or a weekend project for kids aged 10–15 who love gardening and technology. No prior coding experience needed — the AI companion walks you through every step.
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 launch the AI companion, or send a WhatsApp message. It will diagnose your circuit, verify your code, and suggest fixes in real time.
Can I use Blynk or Adafruit IO instead of ThingSpeak?
Yes. The provided code targets ThingSpeak, but the AI companion can help you modify it for Blynk or Adafruit IO using the same ESP32 and DHT22.
Is soldering required?
No soldering — all connections are made on a 400-point breadboard with included male-to-male jumper wires.
How long does the battery actually last?
With 15-minute wake cycles and deep sleep in between, the included 2000mAh LiPo lasts around 3 months; you can extend this by increasing the sleep interval in the code.
Greenhouse — ESP32 wakes every 15 minutes, reads DHT22, posts to ThingSpeak and goes back to deep sleep. 3-month battery.
