This tutorial will show you how to use your Temperature/Humidity TinyShield.
This TinyShield lets you measure temperature and humidity from the TinyDuino. Based around the Silicon Labs Si7020-A10 sensor, this allows for accurate temperature measurement (+- 0.4C) and precision relative humidity readings.
This TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
Here is a link to a sample sketch (zip) and library (zip) for the Temperature / Humidity TinyShield, make sure to put the downloaded, unzipped library folder under your Arduino/libraries folder. If you're new to using Arduino or TinyCircuits, click here for how to set up the Arduino IDE to upload the sketch.
Plug in your TinyDuino to your computer with the USB TinyShield and the Temperature / Humidity TinyShield attached.
Open the Arduino IDE and open up the example sketch that you have downloaded. Then upload it to the TinyDuino.
Open up the Serial Monitor (at 115,200 baud) and you should see the temperature and humidity data that is being read from the sensor.
