Why pick an Adafruit temperature/humidity sensor?
If you’re looking to make greenhouse project or to check the temperature of a room, this is the component for you. You can accurately detect and log even small changes using additional components, or simply get a serial readout using a computer-running Arduino IDE. An on-board PTFE filter aids in keeping the sensor clean without compromising results.

What is the temperature/humidity sensor compatible with?
This sensor uses I2C to communicate with an Arduino or other microcontroller. The I2C interface is compatible with the Uno, Mega 2560, Leonardo and Due Arduino boards. The I2C interface allows for the connection of multiple devices on the same two communication lines – which enables you to have up to eight displays working simultaneously.

What library do I need for my Arduino?
You will need Adafruit’s library, available here to programme your Arduino board and control this altimeter with temperature/humidity sensor.
