The Barometric Pressure Unit is equipped with a Bosch bmp280 pressure sensor to accurately measure atmospheric pressure and estimate altitude. With a relative accuracy of 0.12hPa, it can detect a 1m height difference. The temperature drift coefficient is low at 1.5 Pa/K, ensuring precise temperature compensation. Additionally, the chip includes an integrated temperature sensor.

Applications include wearable devices, motion tracking, and UAV attitude determination. The unit supports low power consumption and features an internal integrated 5-segment filter. It is compatible with development platforms like Arduino and uiflow (Blockly, Python) and includes 2x LEGO compatible holes for versatile mounting options.

Package Includes:

• 1x Barometric Pressure Unit
• 1x Grove Cable (5cm)
