TEMPERATURE / HUMIDITY TINYSHIELD
ASD2511-R-T
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.

TinyDuino Power Requirements
o Voltage: 3.0V - 5.5V
o Current:
o 150uA (Active Mode).
o 60nA (Standby)
o Due to the low current, this board can be run using the TinyDuino coin cell option
Pins Used
o A5/SCL - I2C Serial Clock line
o A4/SDA - I2C Serial Data line
Dimensions
o 20mm x 20mm (.787 inches x .787 inches)
o Max Height (from lower bottom TinyShield Connector to upper top TinyShield
Connector): 5.11mm (0.201 inches)
o Weight: 1 gram (.04 ounces)
NOTES
o 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.
o This sensor has a hole in the top of it for measuring humidity, care should be taken to
not get debris in this opening.
