- 260-1260 hPa의 측정 범위와 24비트 측정 데이터를 25Hz 주기로 읽을 수 있습니다.
- 3.3V/5V 시스템과 사용이 가능하며, I2C 인터페이스를 가지고 있습니다.
특징
-
The LPS25 has a wide measurement range of 260-1260 hPa with 24-bit pressure data measurements that can be read up to 25 times a second (Hz), 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 within 0.2 hPa after calibration (± 1 hPa before calibration).
These days, helpful little sensors like the LPS25 are often quite little and tend to come in surface-mount packages that make them tricky to use with breadboards. With that in mind, we've taken the LPS25 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 3.3V logic level, like a Raspberry Pi or CircuitPython compatible Metro M4 Express, or with a 5V logic level device like a Metro 328 or Arduino Uno.
