The Altimeter Module is a high resolution (20 cm) electronic altimeter sensor. It will give extremely accurate altitude, pressure, and temperature readings.
The module includes a high-linearity barometric pressure sensor and a high-resolution temperature output, allowing implementation of an altimeter/thermometer without any additional sensors. Different operation modes allow the user to optimize for conversion speed or current consumption. The module is designed for use with a large variety of microcontrollers with different voltage requirements. This module is well-suited for high-altitude ballooning and has been used with great success in that role.
