Product Description:
YJJ BMP280 Ultra-Low Power Digital Barometric Pressure Sensor Is Used in Field of Meteorology
Features:
BMP280 is an absolute pressure sensor designed for mobile applications.The sensor module is packaged in an extremely compact package.Its small size and low power consumption allow it to be implemented in battery-powered devices such as mobile phones, GPS modules or watches.
As its predecessor, BMP180, the BMP280 is based on Bosch's proven piezoresistive pressure sensor technology with high precision and linearity as well as long-term stability and high EMC robustness.Numerous device operation options provide the highest flexibility for optimizing devices for power consumption, resolution, and filter performance.Developers are provided with a set of tested defaults (such as use cases) to simplify the design as much as possible.
application
- enhanced GPS navigation (e.g., time improvement, dead reckoning, slope detection)
- indoor navigation (floor detection, elevator detection)
- outdoor navigation, leisure and sports applications
- weather forecast
- healthcare applications (e.g. spirometry)
- vertical speed indication (e.g. rise/fall speed)
Pin description:
Pin1: VCC (3.3v power supply)
Pin2: GND
Pin3: SCL (I2C communication mode clock signal)
Pin4: SDA (I2C communication mode data signal)
Pin5: CSB (pin used in SPI communication mode, not used this time, can be suspended)
Pin6: SDO (sensor address control bit, when connecting GND, the device address in I2C is 0xEC, and the high level is 0xEC+ 1, this time connecting GND)
Sensor test range:
Temperature: - 45 ℃ ~ + 85 ℃
Atmospheric pressure: 0~20000hPa (hpa)
Main measurement modes:
Sleep Mode: when the current reaches the level of uA, the typical value is 0.1ua and the maximum value is 0.3ua. All measurement work stops.
Normal Mode: Normal operation, relevant working interval time can be controlled through register.
Forced Mode: the main control initiates a collection command, the sensor collects a signal, and then enters Sleep Mode, waiting for the next arousal (this time it is useless).
All registers and their addresses in the BMP280 sensor are shown below. Please refer to the data manual for more details.
