This is a simple, compact breakout board for the Silicon Labs Si7020 I2C Temperature and Humidity Sensor. You can use this sensor to measure temperature and humidity in any of your DIY projects.
+/- 0.4 degree C accuracy for temperature
+/- 3% accuracy for relative humidity.
I try to supply mostly sensors with the protective cover. With that said, sometimes based on availability, I'm not able to procure them so some orders may not have the white protective cover. Please let me know if this becomes an issue for your application.
Unit comes assembled and a basic DMM test is performed for connectivity and shorts to ground.
Why did you make it?
This breakout board was created to be a low cost plug and play addition to the Electric Imp. It may also be plugged into a breadboard or wired to work with any other microcontroller platform such as Arduino, Teensy, etc, etc, etc...
What makes it special?
The PCB is made in the USA by Oshpark and the boards are hand assembled and tested in the US. It is currently the only Temperature and Humidity sensor that is both plug in compatible with Electric Imp and comes with example code to read the sensor and push measurements to data.sparkfun.com. This data can then be linked to the imp.guru web app at http://imp.guru so that you can see data plotted over time and share your data on social media.

Worked great
Bought this board to compare readings to our productions samples. Worked great and verified that the readings we were getting from the production samples were correct.

Great temp & humidity breakout
This is a great i2c sensor when you need humidity along with temperature. My only concern (and it likely has nothing to do with the breakout board) seems to be the accuracy of the temperature reading. We're finding some of the sensors readings about 1.5 degrees high as compared to the average of 4 Precon 10K NTC thermistors and other devices. That being said, we'll continue to purchase these and introduce an "adjustment" to the reading as necessary.
