Please don't mischoose your needsBMP280 3.3V:BMP180 Compare with BMP280: has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!This precision sensor is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accurac  Typical application:Enhancement of GPS navigatione.g.time-to-first-fix improvement,dead-reckoning,slope detectionIndoor navigation(floor detection,elevator detection)Outdoor navigation,leisure and sports applicationsWeather forecastHealth care application(e.g. sirometry)Vertical velocity indication(e.g. risk/sink speed)Target devicesHandsets such as mobile phones ,table PCs,GPS devicesNavigation systemsPortable health caredevicesHome weather stationsFlying toysWatchesPCB size:(L*W)1.52* 1.20cm/0.60"*0.47"What is the difference between BME280 and BMP280:BME280: Pressure, temperature and humidity sensor BME280, the precision sensor from , is soldered onto PCB.Not only the pressure and the temperature, this sensor can measure humidity.It uses both I2C and SPI (supports 3-, 4-wire SPI) interfaceSpecifications: Supply Voltage: 1.8 - 5V DC Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz) Operational Range: Temperature: -40 to +85°C Humidity: 0-100% Pressure: 300-1100 hPa Resolution: Temperature: 0.01°C Humidity: 0.008% Pressure: 0.18Pa Accuracy: Temperature: +-1°C Humidity: +-3% Pressure: +-1Pa I2C address SDO LOW : 0x76 SDO HIGH: 0x77

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.
