BME280 Sıcaklık ve Nem ve Barometrik Basınç Sensör Modülü

BME280 Sıcaklık ve Nem ve Barometrik Basınç Sensör Modülü

 

    Bosch firmasının üretmiş olduğu, sıcaklık, barometrik basınç ve neme ölçümü yapabilen BME280 sensörü kullanılmış, sensör modülüdür.3 farklı türde ölçümü tek ürün ile yapabilme imkanı vermektedir.  Bu sensör hava durumunun algılanması için kullanılabilir. 

    Bosch'un bu hassas sensörü, nem oranını ±% 3 doğrulukla, barometrik basıncı ± 1 hPa mutlak hassasiyetle ve sıcaklık ile ± 1.0 ° C doğrulukla ölçme imkanı vardır. Basınç yükseklik ile değişir ve basınç ölçümleri çok iyi olduğu için ± 1 metre veya daha iyi doğrulukta bir altimetre olarak da kullanabilirsiniz..

     Pcb üzerine lehimlenmiş olarak ulaşmaktadır. 3.3V besleme ile kullanıma uygudur. I2C ve/veya SPI haberleşme türleri ile sensör ile iletişim kurabilme imkanı vardır.

 


     The BME280 is the next-generation of sensors from , and is the upgrade to the BMP085/BMP180/BMP183 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but can use either I2C or SPI. For simple easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.

     The BME280 is an integrated environmental sensor developed specifically for mobile applications where size and low power consumption are key design constraints. The unit combines individual high linearity, high accuracy sensors for pressure, humidity and temperature in an 8-pin metal-lid 2.5 x 2.5 x 0.93 mm³ LGA package, designed for low current consumption (3.6 μA @1Hz), long term stability and high EMC robustness.

     The humidity sensor features an extremely fast response time which supports performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor with features exceptionally high accuracy and resolution at very low noise. The integrated temperature sensor has been optimized for very low noise and high resolution. It is primarily used for temperature compensation of the pressure and humidity sensors, and can also be used for estimating ambient temperature.

     The BME280 supports a full suite of operating modes which provides the flexibility to optimize the device for power consumption, resolution and filter performance.
