DIYmall BME280 Humidity Temperature Sensor Barometric Pressure Sensor Module with IIC/I2C for Arduino GY-BME280-5V
BME280 Pressure Temperature Sensor Module with IIC I2C for Arduino <br> Descripton: The BME280 is a great new chip which was originally designed for the next generation of smartphones. <br> It is made up of a very accurate pressure sensor and an associated temperature sensor which helps calibrate the pressure readings. <br>And just for fun they threw in a pretty solid humidity sensor in there as well! <br> So with an I2C connection you have access to enough weather data to make some pretty good predictions for your local area. <br> Or you can just use the pressure sensor with it's abililty to discern the difference in 7.5cm in altitude. <br> The chip contains smarts to smooth out measurements <br>(since it's so sensitive you don't want slamming doors to mess with your pressure readings, for example) which are fully under your control. <br> Connection: <br> GY-BME280 arduino <br> vin----------------vcc <br> GND--------------GND <br> SCL----------------A5 <br> SDA----------------A4 <br> <br> Package Included: <br> 1 X BME280 Pressure Temperature Sensor <br>
