{"product_id":"barometric-pressure-tinyshield-discontinued","title":"Barometric Pressure TinyShield [Discontinued]","description":"\u003cp\u003eThe Barometric Pressure TinyShield allows you to measure barometric pressure (and determine altitude) and temperature with your TinyDuino. Based around the Bosch BMP280 sensor, this allows you to measure barometric pressure with a +\/- 1hPa absolute accuracy, and temperature with a +\/- 1.0C accuracy. This is great for weather applications or accurate altitude measurements in projects such as small drones and rockets.\u003cbr\u003e\u003cbr\u003eThis TinyShield uses I2C communication and incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.\u003c\/p\u003e \u003cp\u003eTo learn more about the TinyDuino Platform, click here\u003c\/p\u003e \u003ch2\u003eSpecification\u003c\/h2\u003e \u003cp\u003e\u003cspan\u003eTo see what other TinyShields this will work with or conflict with, check out the \u003c\/span\u003eTinyShield Compatibility Matrix\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003e\u003cspan\u003eBosch BMP280 Barometric Pressure Sensor\u003c\/span\u003e Specs\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan\u003ePressure Range: 300 -\u0026gt; 1100 hPa (equiv to +9000 to -500m above\/below sea level)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eRelative Accuracy: +\/- 0.12 hPa, equiv to +\/- 1m\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eAbsolute Accuracy: +\/- 1 hPa\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eAbsolute Accuracy Temperature: +\/- 1.0C\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eTinyDuino Power Requirements\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan\u003eVoltage: 3.0V - 5.5V \u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\n\u003cspan\u003eCurrent: 139uA (Normal Mode).  \u003c\/span\u003eDue to the low current, this board can be run using the TinyDuino coin cell option\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003ePins Used\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eA5\/SCL - I2C Serial Clock line\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eA4\/SDA - I2C Serial Data line\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003cspan\u003e20mm x 20mm (.787 inches x .787 inches)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eMax Height (from lower bottom TinyShield Connector to upper top TinyShield Connector): 5.11mm (0.201 inches)\u003c\/span\u003e\u003c\/li\u003e \u003cli\u003e\u003cspan\u003eWeight: 1 gram (.04 ounces)\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003e\u003cspan\u003eDownloads\u003c\/span\u003e\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eTutorial\u003c\/li\u003e \u003cli\u003eBosch BMP280 Barometric Pressure product page\u003c\/li\u003e \u003cli\u003eDatasheet\u003c\/li\u003e \u003cli\u003eSchematic\u003c\/li\u003e \u003cli\u003eEagle Files\u003c\/li\u003e \u003cli\u003eSample Arduino code\u003c\/li\u003e \u003cli\u003eCAD 3D and 2D Files\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\u003cspan\u003eYou 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.  \u003cem\u003e\u003cstrong\u003eWarning:\u003c\/strong\u003e 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.
