# ESP-NOW Dual Sensor Link

Day 76 of the 100 Days 100 IoT Projects collection. Board: ESP8266.

Two ESP8266 nodes exchange DHT11 readings bidirectionally over ESP-NOW, each with its own display. True peer-to-peer sensing.

## How it works

Two ESP8266 nodes take turns as sender and receiver, each broadcasting its own DHT11 readings while displaying the other's. Both boards end up showing both locations' climate — a genuinely bidirectional conversation between peers, no server involved.

## What you'll learn

- Bidirectional ESP-NOW
- Peer data synchronization
- Mirrored sensing
- Server-free communication
