Product Description

BMP280 air pressure sensor . The connection to a microcontroller such as Arduino or ESP Module or to Raspberry Pi is made using I2C or SPI. The BMP280 can ONLY measure air pressure and temperature.

Technical features BMP280:

The BMP280 module comes with BMP280 sensor , which is an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183.
This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI.
This precision sensor is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy
Peak current: 1.12mA
Temperature measuring range: from -40°C to +85°C
Pin pitch: 2.54mm
Module size: 11.5mm*15mm

Pinout

VCC: Power source of 3.3VDC
GND: Ground
SCL: Serial Clock
SDA: Serial Data
CSB: CSB pin to GND to have SPI and to VCC(3.3V) for I2C. It’s an input to the chip.
SDO: Serial Data Out / Master In Slave Out pin, for data sent from the BMP280 to your processor

How to use BMP280 Module?

The BMP280 module operates from 3.3V so requires 3.3V power and must be driven with 3.3V logic levels. If needed to operate at 5V, it can be done using voltage regulator and level shifters as it doesn’t contain one. It is typically recommended to operate it on 3.3V and maximum at 3.6VDC. The module GY-BMP280 module simply supports both I2C and SPI interfaces and comes with default I2C address of 0x76. The Chip Select (CSB) and Serial Data Output (SDO) pins of the BMP280 are necessary only when SPI-based (four-wire) communication is applied. I2C is a two wire interface SDA SCK.

Leave pin 6 of the module (SDO) unconnected to set the I2C address to 0x76 – the on-board resistor pulls the SDO pin low setting the address to 0x76.

To change the I2C address to 0x77, connect pin 6 of the module (SDO) to Vcc which would typically be the 3.3V supply.

Pin 5 of the module (CSB) must be connected to Vcc to select the I2C interface. This is already done by an on-board pull-up resistor, so pin 5 can be left disconnected when using the I2C interface.
