DESCRIPTION

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.

NOTES

You can also use this shield without the TinyDuino – there are 0.1″ spaced connections for power, ground, and the two I2C signals along the side of the TinyShield to allow you to connect a different system. Warning: Revision 4 boards have a mistake on the silkscreen, the pin marked VCC is actually SCL, the pin marked SCL is actually SDA, and the pin marked SDA is actually VCC. If you connect this up the way it is marked you will not damage the board.
This sensor has a hole in the top of it for measuring humidity, care should be taken to not get debris in this opening.
