Barometric sensors are only starting to gain traction in mobile devices. They first appeared in the Samsung Galaxy S III (GT-I9300), which launched in mid-2012. It carried the STMicroelectronics LPS331AP sensor, which appeared once more in the Nokia Lumia 1020.
Teardown.com detected nine design wins for the Bosch Sensortec BMP180 barometric sensor (pictured).
The Bosch Sensortec BMP180 has the most occurrences, with nine design wins. Its apparent successor, the BMP280, was observed twice. The BMP180 has been seen throughout the data sample period, while the BMP280 showed up in November 2013. It is interesting to note that the STMicroelectronics IC costs about twice as much as the Bosch Sensortec parts based on our costing models. Table 3 shows their occurrence information.
Humidity sensors were introduced to the mobile device space by the Samsung Galaxy S4 (GT-I9505) in April 2013. Only one other device with this function has been observed so far in our Deep Dives, that being the Samsung Galaxy Note 3 (SM-N900A). Both units use the Sensirion SHTC 1.
