  "description": "Barometric pressure and temperature sensor based on the ST ILPS22QS. Dual full-scale modes cover up to 1260 hPa or 4060 hPa, with 24-bit pressure output and 0.5 hPa accuracy. Integrated Qvar electrostatic sensing supports touch and gesture detection. Communicates over I²C (up to 1 MHz), SPI (up to 10 MHz), or I3C (up to 12.5 MHz) to provide data at output rates of up to 200Hz with a 128-sample deep FIFO buffer.",
