Grove - Temperature, humidity & barometer sensor (BME280)

Grove - Temperature, humidity & barometer sensor (BME280)

Description

The Grove - Temperature, Humidity & Barometer Sensor (BME280) is a highly accurate combined humidity, barometric pressure and temperature sensor with low power consumption. Air pressure can be measured in a range from 300 hPa to 1100 hPa with an accuracy of ±1.0 hPa and temperatures between -40℃ and 85℃ with an accuracy of ±1℃. 

As for humidity, you can obtain a humidity value with a deviation of less than 3%. As air pressure changes with altitude, it can also be used to measure the approximate altitude of a location. This can be calculated with an accuracy of ±1 meter, which also makes it an accurate altimeter.

The sensor can be connected to a microcontroller with I2C (integrated in the Grove socket) or via the SPI bus. A library is also available to simplify the use of this product.

The BME280 is an updated version of the BMP180. The BME280 has a smaller footprint, lower power consumption, fewer noise measurements, higher resolutions for pressure and temperature, lower RMS noise, a newly added SPI bus, more measurement modes, a higher measurement rate and a newly added environmental noise filter. Overall, it is more reliable in providing accurate data on temperature, air pressure, humidity and approximate altitude.

Note:
As the sensor is very sensitive to environmental conditions, please DO NOT touch it with your fingers.

Features

• High-performance environmental detection: With the help of the BME280 module, temperature, humidity and air pressure can be detected simultaneously to achieve a stronger detection effect.
• Robust measuring range: The sensor can operate normally from -40 to 85 °C. The measuring range of the air pressure sensor is between 300 and 1100 hPa.
• Higher measurement accuracy: Only ±1.0 °C deviation in temperature measurement; humidity measurement with an accuracy of ±3 % and barometric pressure measurement with an accuracy of ±1.0 hPa.
• Grove interface: The sensor ensures "plug and play"; and could be versatile for various applications.

Application

• Improvement of GPS navigation
• Outdoor/indoor navigation
• Weather forecast
• Home automation and control
• IoT device
• Barometer

What is Grove?

Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. We offer various Grove Shields to enable a connection to the Grove system with various microcontrollers.
