ESP-NOW Sensor Network

Sensors · Board: ESP8266 · Day 57 of 100

ESP8266 and ESP32 nodes share sensor data and relay states over ESP-NOW. A tiny mesh of cooperating boards.

How it works

Several boards form a small cooperative network: each ESP8266 or ESP32 node shares its sensor readings and relay states with the others over ESP-NOW. No central server is needed — the nodes pass data directly, like a tiny mesh built from spare parts.

What you'll learn

  • Distributed sensor networks
  • Node-to-node data sharing
  • Decentralized architecture
  • Mesh-style cooperation
