We’ve released Seeed Barometer Selection Guide to help you compare different barometer sensors. We will also keep updating the guide.  

Based on Bosch BME280, we made this low-cost and high-precision environmental sensor -- the Grove - BME280 Environmental Sensor (Temperature Humidity Barometer). This BME280 supports both I2C and SPI communication and we provide the Arduino BME280 library.


Grove BME280 provides a precise measurement of not only barometric pressure and temperature, but also the humidity in the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa accuracy, while the sensor works perfectly for temperatures between - 40℃ and 85℃ with an accuracy of ±1℃. As for the humidity, you can get a humidity value with an error less than 3%.


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 of this BME280 breakout board. If you go with I2C, the board also provides 2 I2C addresses for you to select as you want.  


BMP280 vs. BME280 vs. DPS310

We've already released the Grove-BMP280 and Grove-BME 280 barometric pressure sensors, let us show you how powerful Grove-DPS310 is through the comparison of the table below.

In this video I add the 2nd soil moisture sensor to my raspberry pi GROWbox Supervisor System!! The 2nd soil moisture sensor will allow me to monitor both plants at the same time.
In diesem Video stelle ich den Barometer Sensor BME280 von vor. Des Weiteren zeige ich ein kleines Programm mit welchem man die Daten des Sensors auf dem seriellen Monitor der Arduino IDE ausgeben kann.
We have released various types of barometer sensors in recent years. You may find it difficult to make a choice between them. Let's take a close look at them and work out which one is best suited for you!
It's time to look at the Top 40 Raspberry Pi 4 Projects that you can refer to and try building yourself!
