BMP280 3.3V:

BMP180 Compare with BMP280:

has stepped up their game with their new BMP280 sensor, 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 accurac


Typical application:
Enhancement of GPS navigation
e.g.time-to-first-fix improvement,dead-reckoning,slope detection
Indoor navigation(floor detection,elevator detection)
Outdoor navigation,leisure and sports applications
Weather forecast
Health care application(e.g. sirometry)
Vertical velocity indication(e.g. risk/sink speed)
Target devices
Handsets such as mobile phones ,table PCs,GPS devices
Navigation systems
Portable health caredevices
Home weather stations
Flying toys
Watches
PCB size:(L*W)1.52* 1.20cm/0.60"*0.47"



What is the difference between BME280 and BMP280:
BME280: Pressure, temperature and humidity sensor
BMP280: Pressure sensor

Why is it so expensive now?
Since 2021, there is a global shortage of chips, and it is difficult for us to buy chips from agents. Once it drops in price, we will update the price immediately.






BME280, the precision sensor from , is soldered onto PCB.
Not only the pressure and the temperature, this sensor can measure humidity.
It uses both I2C and SPI (supports 3-, 4-wire SPI) interface
