ماژول سنسور فشار SPL06-001 از سنسور SPL06-001 کوچک برای اندازه گیری
فشار استفاده می کند که دقت بالا و توان مصرفی پایینی دارد و می تواند میزان فشار و دما را با هم اندازه گیری کند و افزایش دما، تاثیری در میزان فشار ندارد.
خروجی این سنسور بارومتریک، میزان فشار را به سیگنال 24 بیتی تبدیل می کند و هر سنسور به صورت انحصاری و مستقل، کالیبره می شود. تبادل داده این ماژول از طریق FIFO انجام می شود و میتواند 32 مقدار اندازه گیری شده را در خود نگه دارد و میزان توان مصرفی را به حداقل رساند.
Description:
The SPL06-001 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a low current consumption. The SPL06-001 is both a pressure and a temperature sensor. The pressure sensor element is based on a capacitive sensing principle which guarantees a high precision during temperature
changes. The small package makes the SPL06-001 ideal for mobile applications and wearable devices.
The SPL06-001‘s internal signal processor converts the output from the pressure and temperature sensor elements to 24-bit results. Each pressure sensor has been calibrated individually and contains calibration coefficients. The coefficients are used in the application to convert the measurement results to true
pressure and temperature values.
The SPL06-001 has a FIFO that can store the latest 32 measurements. By using the FIFO, the host processor can remain in a sleep mode for a longer period of time between readouts. This can reduce the overall system power consumption. Sensor measurements and calibration coefficients are available
through the serial I2C interface.
