GY-68 BMP180 Temperature / Barometric Pressure Sensor Module Replace BMP085

BMP180 Barometric Pressure Sensor Module

The BMP180 is a high-precision, ultra-low power, barometric pressure sensor designed for use in mobile devices.

Its performance is excellent, achieving absolute accuracy as low as 0.03 hPa, with extremely low power consumption of only 3 μA.

The BMP180 comes in a compact, powerful 8-pin ceramic LCC (Leadless Chip Carrier) ultra-thin package and can be connected directly to various microprocessors via the I²C bus.

Key Features:
