This is an Arduino library for the DHT series of low cost temperature/humidity sensors. # Adafruit DHT Humidity & Temperature Sensor Library
An Arduino library for the DHT series of low cost temperature/humidity sensors.
Tutorial: https://learn.adafruit.com/dht Tutorial: https://learn.adafruit.com/dht
To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder DHT. Check that the DHT folder contains DHT.cpp and DHT.h. Place the DHT library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE. **You must have the following Arduino libraries installed to use this class:**
# Adafruit DHT Humidity & Temperature Unified Sensor Library
This library also includes an optional class for the
[DHT humidity and temperature sensor](https://learn.adafruit.com/dht/overview)
which is designed to work with the [Adafruit unified sensor library](https://learn.adafruit.com/using-the-adafruit-unified-sensor-driver/introduction).
You must have the following Arduino libraries installed to use this class:
- [Adafruit Unified Sensor Library](https://github.com/adafruit/Adafruit_Sensor) - [Adafruit Unified Sensor Library](https://github.com/adafruit/Adafruit_Sensor)
Examples include both a "standalone" DHT example, and one that works along with the Adafruit Unified Sensor Library. Unified sensor library is required even if using the standalone version.
Recent Arduino IDE releases include the Library Manager for easy installation. Otherwise, to download, click the DOWNLOADS button in the top right corner, rename the uncompressed folder DHT. Check that the DHT folder contains DHT.cpp and DHT.h. Place the DHT library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.
