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
