The Grove BMP280 Barometer Sensor is built around Bosch BMP280, it is a low-cost and high-precision environmental sensor measures the temperature and barometer. This sensor supports both I2C and SPI communication and we provide the BMP280 Arduino library.
Grove BMP280 provides precise measurements of barometric pressure and temperature in the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa absolute accuracy. As for the temperature, the sensor works perfectly for temperatures between - 40℃ and 85℃ with an accuracy of ±1℃.
Owing to its high accuracy on measuring the pressure, and the pressure changes with altitude, we can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well. Another great thing about this module is that you don’t even need to worry about the I2C collisions as it provides both I2C and SPI interfaces. To use SPI, simply de-solder the bonding pads on the back. If you go with I2C, the board also provides 2 I2C addresses for you to select as you want.

works greatit seemed well built, was clearly labeled, and worked exactly as described
NiceI bought these to provide my children some learning and fun. It has done that and more, since the COVID-19 isolation has driven me to stay at home.
It works really greatI bought this for a project I built as my final project in an Internet of Things class. It works really great.
no problemsOne months in continuous use; no problems so far.
Five StarsGreat sensors. Very easy to use.
