ESP32 + DHT22 Greenhouse Climate Monitor Kit – ESP-NOW Wireless

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 stepping into your greenhouse and instantly checking temperature and humidity on a remote display, no Wi-Fi router needed. With this kit, you program two ESP32 microcontrollers to exchange real-time sensor data over ESP-NOW, a low-power peer-to-peer protocol built into every ESP32. It’s the foundation for scalable, off-grid agricultural monitoring.

What You'll Build

You’ll assemble a transmitter unit that reads DHT22 sensor data and a receiver unit that displays the readings on an OLED screen. The two ESP32 boards communicate directly over ESP-NOW, so you get live temperature and humidity updates without any router or cloud dependency. Perfect for a greenhouse setup where you want to monitor conditions from a distance.

What You'll Learn

• How to set up ESP-NOW communication between two ESP32 boards without a Wi-Fi network.
• Reading and interpreting DHT22 digital temperature and humidity sensor data.
• Displaying real-time data on a 0.96-inch OLED using I2C protocol.
• Building a wireless sensor network that can be scaled for multiple nodes.
