Adafruit BMP180 Barometric Pressure/Temperature/Altitude Sensor- 5V ready

This precision sensor from Bosch offers a cost-effective solution for measuring barometric pressure and temperature. Changes in pressure with altitude enable its use as an altimeter, ideal for various applications.

The sensor is mounted on a PCB featuring a 3.3V regulator, I2C level shifter, and pull-up resistors on the I2C pins, ensuring reliability and stability. The BMP180 is the advanced successor to the BMP085, yet it maintains full compatibility, allowing seamless integration with existing BMP085 firmware and software.

Unlike the BMP085, the BMP180 lacks an XCLR pin, requiring I2C bus queries to check data readiness. The sensor's 5V compliance, thanks to the integrated 3.3V regulator and I2C level shifter circuit, ensures safe usage with 5V logic and power.

Setup is straightforward; connect the VIN pin to a 5V source, GND to ground, SCL to I2C Clock, and SDA to I2C Data. Arduino users can easily employ the BMP085/BMP180 library for precise temperature, pressure, and altitude data acquisition.

Comprehensive tutorials and software guides simplify installation and operation, detailing altitude calculations based on sea-level barometric pressure, enhancing understanding and optimizing sensor use.
