# DHT2pin
|
|
|
|
Arduino library for experimental 2 pin DHT library.
|
|
|
|
|
|
## Description
|
|
|
|
**NOTE: THIS LIB IS NOT TESTED EXTENSIVELY YET SO USE WITH CARE**
|
|
|
|
This library is an experimental version of the DHT library that uses 2 pins.
|
|
One pin for all read actions and one pin for write actions. This way one does
|
|
not need to switch a pin between **INPUT** and **OUTPUT**.
|
|
|
|
Note: It needs a diode in the hardware between the input pin of the MCU
|
|
and the data pin of the DHT sensor.
|
|
The output pin of the MCU is directly connected to the data pin of the DHT sensor.
|
|
|
|
It was made after a request which also referred to the links below.

## Future
|
|
|
|
- no active development planned
|
|
- improve unit tests (constants)
