Description: Measuring the absolute pressure of the enviroment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor compatible with determining the height of your robot, plane . Using a sensor as capable as the you can achieve accurary of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw compatible with battery powered applications. The comes fully calibrated and ready to use. As the device operates over we've added optional pull ups that can be enabled using the PU (pull up) jumper on the board compatible with your convenience and ease during breadboarding. Using , the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation. Features: 1.8V to 3.6V Supply Voltage Low power consumption - 0.5uA at 1Hz interface Max Speed: 3.5Mhz Very low noise - up to 0.02hPa (17cm) Full calibrated Pressure Range: 300hPa to 1100hPa (+9000m to -500m) Weight: 1.18g Size: 21mm x 18mm has stepped up their game with their new sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the / / . This sensor is great compatible with all sorts of weather sensing and can even be used in both and !
