# ESP-NOW Sensor Network

Day 57 of the 100 Days 100 IoT Projects collection. Board: ESP8266.

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
