Hi everyone,

I’d like to share an update to **myDHT** , an Arduino library for **DHT11** and **DHT22** sensors.  
Version **2.0.2** is now available directly via the **Arduino Library Manager**.

The main goal of this release was to make the library **safer and clearer for beginners** , while still providing **full control and diagnostics for advanced users**.

### What’s new in the 2.0.x series

#### Layered API design

**myDHT – beginner layer**

- Safe read intervals enforced automatically
- Internal caching
- Simple API: `getTemperature()`, `getHumidity()`, `dewPoint()`, `HiIndex()`

**myDHTPro – advanced layer**

- Full protocol-level access
- Debug and test modes
- Asynchronous reads (state-machine based)
- Raw pulse timing access
- Multi-sensor support

#### Reliability improvements

- Corrected minimum sampling intervals for **DHT11** and **DHT22**
- Safe read handling (`readSafe`)
- Improved behavior in memory-optimized builds

#### Tested on real hardware

- Arduino Uno & Nano
- DHT11 and DHT22

#### Demo projects

Beginner-friendly demo projects showing real-world use cases:

- Zero-configuration weather monitor
- Dew point greenhouse indicator
- Heat index analog gauge (servo-based)

The library is fully standalone (no external dependencies) and is intended to be both **reliable in practice** and **useful for learning how DHT sensors actually work internally**.

**GitHub:**

>
> Advanced Arduino library for DHT11 and DHT22 sensors with auto-detect, sanity-check, debug logging, memory-optimized build, asynchronous reads, and MultiSensorManager support.

Feedback, testing on other boards, and suggestions are very welcome.

Thanks,  
Toni
