# DHT11 Data Logger

Day 48 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

The Pico 2W logs temperature and humidity over HTTP for later analysis. Simple, reliable environmental recording.

## How it works

Every few minutes the Pico 2W reads the DHT11 and POSTs the values to a logging endpoint, building a timestamped record over days and weeks. Later you can open the log and see exactly how temperature swung through each day. Boring in the best way — reliable data capture.

## What you'll learn

- HTTP POST logging
- Timestamped datasets
- Long-term environmental recording
- Log file formats
