The Barometric Pressure TinyShield allows you to measure barometric pressure and temperature with your TinyDuino. Based around theBosch 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, such as for small drones or rocketry projects.
This 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.
You can also use this shield without the TinyDuino – there are 0.1″ spaced holes for power, ground, and the two I2C signals along the side of the TinyShield to allow you to connect a different system.
