MCU-3115 MPL3115A2 Air pressure altitude intelligent temperature sensor module
Thanks to the MPL3115A2's built-in full compensation algorithm and altitude algorithm, the sensor can directly output 20-bit pressure readings or 20-bit altitude readings, as well as 12-bit temperature readings, with an effective resolution of up to 30 cm. From the start of the measurement to the SI unit output (pascals, meters and degrees Celsius), the MCU only needs to perform I2C read and write operations, without any additional data processing, which effectively saves MCU resources while greatly reducing system power consumption.
The MPL3115A2 also supports on-chip offset adjustment of pressure, height and temperature, autonomous data acquisition, limit alarm and extreme value recording. The sensor also provides up to 128x oversampling rate, 32 FIFO sampling buffers for data storage, and the host can read the data on demand.
The MPL3115A2 is a smart choice for pressure and height measurements.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
