TinyHiker uses a pressure/temperature sensor for altitude and temperature measurement, a 9DOF- (Gyro + Accelerometer + Magnetometer) for pedometer, a magnetometer for the compass, and a real time ...

Manufactured by Hope Microelectronics, the HP203B is a high-precision barometer and altimeter that measures the pressure and the temperature by an internal 24-bit ADC and compensates using a patented ...

The altimeter is one of the basic and most essential devices used in-flight systems, drones, space rockets, and submarines to measure the altitude of a location (known as altimetry for land and ...

While traditionally a project geared more toward the model rocket crowd, a lot of people are flying quadcopters these days, and knowing the altitude your RC aircraft reached is a nice thing to know.
