Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy!\u003c\/p\u003e\n\u003cp\u003eThe BME280 is the next-generation of sensors from Bosch 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.\u003c\/p\u003e\n\u003cp\u003eNice sensor right?

BMP180 combines barometric pressure, temperature and altitude. The I2C allows easy interface with any microcontroller. On board 3.3V LDO regulator makes this board fully 5V supply compatible. BMP-180 can measure pressure range from 300 to 1100hPa (+9000m to -500m relating to sea level) with an accuracy down to 0.02hPa (0.17m) in advance resolution mode. BMP-180 is an improved replacement for BMP-085 sensor.

The BMP180 delivers the uncompensated value of pressure and temperature.The microcontroller sends a start sequence to start a pressure or temperature measurement. After converting time, the result value (pressure or temperature respectively) can be read via the I2C interface. For calculating temperature in °C and pressure in hPa, the calibration data has to be used. These constants can be read out from the BMP180 E2PROM via the I2C interface at software initialization.The sampling rate can be increased up to 128 samples per second (standard mode) for dynamic measurement. In this case, it is sufficient to measure the temperature only once per second and to use this value for all pressure measurements during the same period.\u003c\/p\u003e","brand":"Others","offers":[{"title":"Default Title","offer_id":42290981044415,"sku":"MLE00469","price":40.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/09014f2c416c5038b3cef4a928f72ffe.jpg?v=1735816056"},{"product_id":"mpl3115a2-i2c-barometric-pressure-altitude-temperature-sensor","title":"Adafruit MPL3115A2 I2C Barometric Pressure Altitude Temperature Sensor | Code: 1893","description":"\u003ch1 class=\"product-name-small\"\u003e\u003cstrong\u003eMPL3115A2 - I2C Barometric Pressure\/Altitude\/Temperature Sensor\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cp\u003eThis MPL3115A2 - I2C Barometric Pressure\/Altitude\/Temperature Sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude.
