DHT. Open your Arduino IDE and go to Sketch > Include Library > Manage Libraries. The Library Manager should open. Search for DHT on the Search box and install the DHT library from Adafruit.. LCD I2C.

The DHT20 is a humidity and temperature sensor. The sensor has a fixed address of 0x38.It is not known if the address can be changed. The library must be initiated by calling the begin() function..

In this Arduino Uno based project we are going to measure ambient temperature and humidity and display it on a 16x2 LCD screen. A combined temperature and himidity sensor DHT11 is used with Arduino ...

The past month or so I've been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up ... since both ICs communicate to the Arduino via the 2-wire I2C port; ...
