Wireless Greenhouse Climate Monitor Using ESP32 ESP-NOW — No Router Needed

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Step into precision agriculture with a multi‑node wireless climate monitor designed specifically for greenhouses. Three ESP32 development boards, each paired with a DHT22 sensor, create a peer‑to‑peer ESP‑NOW mesh that streams real‑time temperature and humidity to a central OLED display. No router, no cloud — pure local control over your growing environment.

What You'll Build

A complete ESP‑NOW sensor network that maps temperature and humidity across three distinct zones in your greenhouse. Sensor nodes placed near entry, mid‑house, and far‑wall feed readings to a receiver unit every few seconds. The 0.96‑inch OLED cycles through each location’s data, letting you spot micro‑climate shifts instantly. The system is line‑of‑sight 200+ metres and entirely independent of WiFi infrastructure.

What You'll Learn

• Provisioning multiple ESP32 boards as ESP‑NOW peers with unique MAC addresses
• Parsing and transmitting DHT22 temperature/humidity data wirelessly
• Implementing a star‑topology sensor network without any access point
• Managing signal integrity using decoupling capacitors and pull‑up resistors
