The BME280 is a four-in-one sensor that can simultaneously detect temperature, humidity, air pressure and calculate altitude data. Temperature is air temperature of the environment, which affects people's feelings of heat and cold. Humidity is the amount of moisture in the air. The higher the humidity, the more humid the air. Pressure is the pressure of air. When air pressure is low, many people would feel stuffy intuitively. Altitude is the vertical distance from the sea level. The higher the altitude, the lower the pressure. Moderate temperature, humidity and air pressure can bring people a very comfortable environment.

BME280 Card is a powerful environmental detection tool that features BOSCH BME280 sensor. It can comprehensively obtain field data, providing strong support for outdoor sports, field monitoring, and plateau equipment projects.

↑ Longan Cards system consists of Cards and Boards. There are many gold finger antennas on Card and several gold finger sockets on Board. They are combined together through sockets interpolation, which is intuitive and easy to use. With this unified and flexible interface, you can realize a variety of ideas. Many more Boards with different themes would luanch to help people explore more fun.

↑ Longan Cards modules are classified into many types. Firstly, the main control cards which are the heart of Cards system, run the code and take charge of the exchange of data between modules. Besides Carduino, you can also use MicroBit, Arduino and other development board through connection board. The sensor cards can detect data of surrounding such as temperature and air pressure, etc. The inputs cards allows you to do some operations, such as buttons, knobs, etc. The output cards give feedback in various forms, such as buzzers, motor drives, etc. The communication cards can transmit data in many ways, such as Bluetooth and 4G network. The power cards supply power for electronic projects, including batteries, DC, etc. And other cards, mainly do some auxiliary work, such as expansion, code downloading, etc.

↑ STEM is an acronym for science, technology, engineering, and math. STEM education began in the United States in the 1990s. It is an interdisciplinary teaching method that combines STEM content and real life situations, which helps stimulate students’ original curiosity and thirst for knowledge and novelty. Longan Cards contains dozens of modules, involving a wide range of knowledge in the process of use, including electronic circuit, mechanical structurenature, programming, science of nature, daily wisdom, and humanities, etc. It is a powerful tool for STEM education at fields of electronic prototyping, science experimentation and DIY project.
