Description

BMP280 Barometric Pressure Sensor Module specially designed for mobile applications. The pressure sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow for the implementation in battery powered devices. A barometric pressure sensor is ideal for measuring various weather conditions. This BMP280 sensor has high accuracy and low cost making it an ideal solution for precision pressure measurements of up to ± 1 hPa and a temperature of up to ± 1.0 ° C. Because the pressure changes with altitude and pressure measurements are very accurate, you can use this sensor and the altimeter ± 1-meter accuracy.

Features:

BMP280
Power supply: 3-5v (internal low dropout regulator)
Field range: ± 4800uT
Pressure range: 300-1100hPa
Temperature Accuracy: ± 1.0 ° C
Using Immersion Gold PCB, machine welding process to ensure quality

Pin supply:

Vin– supply pin. Since the image using 3V DC, the board has a built-in voltage regulator that receives 3-5V DC and converts them to 3V. To use the module to be powered from the same voltage as the Arduino board.
3Vo – this is the output from 3.3V regulator. It can provide up to 100mA
GND – Point Table

SPI pins:

All pins have level shift circuit to bring to a logical level 3 V to 5 V. Use any logical level is Vin pin.

SCK – SPI Clock pin, entry
SDO – Serial Data Out / Master In Slave Out pin, for sending data from the processor BMP183
SDI – Serial Data In / Master Out Slave In pin, for sending data from the processor to BMP183
CS – Chip Select pin, entry form, must be connected to “low” to start transmission SPI
