{"product_id":"adafruit-lps22-pressure-sensor-stemma-qt-qwiic-lps22hb","title":"Adafruit LPS22 Pressure Sensor - LPS22HB","description":"\u003cp\u003eThis absolute pressure sensor, \u003cstrong\u003eST LPS22HB\u003c\/strong\u003e (a.k.a \u003cstrong\u003eLPS22\u003c\/strong\u003e) can quickly and easily measure air pressure, useful when you want to know about the weather (are we in a low-pressure or high-pressure system?) or to determine altitude, as the air thins out the higher we get above sea level.\u003c\/p\u003e\n\u003cp\u003eFor example, at sea level, the official pressure level is 1013.25 hPa\u003cstrong\u003e. \u003c\/strong\u003eYou can use this sensor to measure the current pressure where you are right now to compare.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eLPS22\u003c\/strong\u003e is the Worlds Smallest sensor (according to ST) and it is surprisingly tiny - only 2x2mm. So you'll see this sensor show up in wearables and watches where space is at a premium. It has a wide measurement range of \u003cstrong\u003e260 to 1260 hPa \u003c\/strong\u003ewith 24-bit pressure data measurements that can be read up to\u003cstrong\u003e 75 times a second (Hz)\u003c\/strong\u003e, you can be confident that you always have an up to date and precise measurement. It's pretty dang accurate too, with the ability to measure\u003cstrong\u003e \u003c\/strong\u003eabsolute pressure within 0.1 hPa after one-point calibration (± 1 hPa before calibration).\u003c\/p\u003e\n\u003cp\u003eThese days, helpful little sensors like the LPS22 are often quite little and tend to come in surface-mount packages that make them tricky to use with breadboards. With that in mind, Adafruit have taken the LPS22 and put it on a breakout board with level shifting circuitry and a voltage regulator. This means that not only can you use it with a breadboard, but you can use it with a wide range of devices that have either a \u003cstrong\u003e3.3V logic level\u003c\/strong\u003e, like a Raspberry Pi or CircuitPython-compatible Metro M4 Express, \u003cstrong\u003eor with a 5V logic level\u003c\/strong\u003e device like a Metro 328 or Arduino Uno.\u003c\/p\u003e\n\u003cp\u003eFurthermore, they've included \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSparkFun Qwiic\u003c\/a\u003e compatible \u003ca href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSTEMMA QT\u003c\/a\u003e connectors for the I2C bus so you don't even need to solder!
