Odyssey Personality - Temperature & Humidity

Introduction

This personality measures temperature and relative humidity using the Silicon Labs Si7020 sensor.

How To Use

After connecting the Odyssey board with your smartphone app, select the pre-defined temperature and humidity personality. Press the respective buttons to see the current temperature and humidity displayed in the app.

How It Works

The Si7020 from Silicon Labs is a 2nd generation relative humidity and temperature sensor. It combines fully factory-calibrated humidity and temperature sensor elements with an analog to digital converter, signal processing and an I2C host interface. Patented use of industry-standard low-K polymer dielectrics provides excellent accuracy and long term stability, along with low drift and low hysteresis. The innovative CMOS design also offers the lowest power consumption in the industry for a relative humidity and temperature sensor.

Note that the temperature readings will be higher than actual ambient temperature when the board is powered by a USB cable, especially so when the MAX 10 FPGA board is attached to the sensor board. This is due to the power dissipation of the power regulators on the board.
