KS0405 Keyestudio BMP280 Module (Black and Eco-friendly)

Keyestudio BMP280 Module(Black and Eco-friendly)

Overview

The keyestudio BMP280 module mainly uses the BMP280 sensor, a temperature and air pressure sensor, which is an absolute air pressure sensor designed for mobile applications.
The sensor module is available in an extremely compact package with small size and low power consumption. It features proven piezoresistive pressure sensor technology with high accuracy and linearity, as well as long-term stability and high EMC robustness. The multiple device working options provide the ultimate flexibility; we can optimize the device in terms of power consumption, resolution and filtering performance.
The module has two modes: I2C communication and SPI communication mode. When using the BMP280 module, users can choose the communication method according to their own needs.

Technical Parameters

Operating voltage: DC 5V
Air pressure measurement range: 300hPa~1100hPa (elevation +9000~-500m)
Air pressure measurement error: ±1hPa (±1m)
Air pressure measurement accuracy: 0.18Pa
Temperature measurement range: 0℃~ 65℃
Temperature measurement error: ±0.5℃, maximum ±1℃
Temperature measurement accuracy: 0.1℃

Application field

temperature check
Atmospheric pressure detection
Altitude detection
Indoor navigation (floor inspection, elevator inspection)
Outdoor navigation, leisure and sports apps
Healthcare applications (i.e. spirometry)
Vertical speed indication (i.e. ascending/sinking speed)

Upload the program

Special note: You can download different version of Arduino IDE from the link here:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x

Here we use the Arduino 1.6.1 version to test the BMP280 module in the code. It might fail to compile the test program when using other versions of arduino IDE.

Downloaded Arduino 1.6.1, unzip the software package to open the arduino application.

Follow the hookup guide to connect well the module, and open the arduino software. Note: before open the software, do remember to place the code libraries inside the arduino libraries folder.

Open the arduino software, firstly select the proper Board and COM port in “Tools”.

After that, copy and paste the test code to arduino window. Click to compile and upload the code.

Done uploading the test code, click to open the monitor and set the baud rate to 9600. The monitor will show the current temperature and air pressure.
