BMP180 GY-68 Barometric Pressure Sensor

Description

BMP180 GY-68 Barometric Pressure Sensor This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. Measuring the absolute pressure of the environment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane or projectile. Features: Can measure temperature and altitude. Pressure range: 300 to 1100hPa. High relative accuracy of ±0.12hPa. Can work on low voltages. 3.4Mhz I2C interface. Low power consumption (3uA). Pressure conversion time 5msec. Potable size. Specifications: Pressure range: 300 ~ 1100 hPa (altitude 9000 m ~ – 500 m) Compatible with 3.3V and 5V LCC8 encapsulation: lead-free ceramics carrier encapsulation (LCC) Low power consumption: 5 μA, in the standard model High precision: low power consumption mode, the resolution is 0.06 hPa (0.5 meters); High linear mode, the resolution is 0.03 hPa (0.25 meters) MSL 1 response time: 7.5 ms Standby current: 0.1 μA Size: 15mm * 13mm Pin Configuration: Pin Description VIN(VCC) Power supply (typically 3.3V; some modules support 5V) GND Ground SCL I2C clock line (connect to microcontroller SCL pin) SDA I2C data line (connect to microcontroller SDA pin) Applications: Weather forecast.
