Pressure Sensor

Description

Based on the BMP180 digital barometer, this sensor measures absolute ambient pressure and converts the measured pressure into altitude. With this sensor, you can determine the height of a robot, an aircraft, etc., with an accuracy of 1 meter. The sensor draws only 0.5 uA, making it suitable for battery-powered devices. The BMP180 is fully calibrated and ready to use. Using the I2C interface, it provides pressure and temperature as 16-bit values, which, together with the calibration data inside the device, are used to provide a temperature-compensated altitude calculation. Power supply: 3.6V (from 3V to 5V), consumption: 0.5 uA at 1 Hz, interface: I2C, measurement range: 300 hPa to 1100 hPa (from +9000 m to -500 m), weight: 1.18 grams, dimensions (mm): 10×13.
