TE Connectivity Miniature Variometer Module
TE Connectivity Miniature Variometer Module is a high-resolution altimeter sensor with an SPI and I2C bus interface. This altimeter sensor is hermetically sealed for outdoor devices and has a fast conversion down to 1 ms. This sensor module is a high linearity pressure sensor with an ultra-low power 24-bit ΔΣ ADC with internal factory-calibrated coefficients. This sensor can be interfaced with virtually any microcontroller and finds application in adventure or multi-mode watches, bike computers, dataloggers, mobile altimeter/barometer systems, and variometers
