BMP280 Barometric Pressure & Temperature Sensor
PRECISION SENSOR: Bosch BMP280 sensor used for accurate measurement of atmospheric pressure and temperature in environmental monitoring applications.
ALTITUDE MEASUREMENT: Can also function as an altitude sensor with an accuracy of approximately ±1 meter based on pressure variation.
OPERATING VOLTAGE: Compatible with 3.3V and 5V systems, allowing easy integration with development boards.
COMMUNICATION INTERFACE: Supports both I2C and SPI communication protocols.
PRESSURE MEASURING RANGE: Measures atmospheric pressure from 300 hPa to 1100 hPa, equivalent to approximately +9000 m to -500 m altitude relative to sea level.
TEMPERATURE RANGE: Measures temperature from -40°C to +85°C for reliable environmental sensing.
ACCURACY: Provides ±0.12 hPa relative accuracy and ±1 hPa absolute pressure accuracy under normal conditions.
LOW POWER CONSUMPTION: Consumes approximately 2.7 µA at 1 Hz sampling rate, making it suitable for battery-powered and IoT devices.
BUILT-IN SUPPORT CIRCUITS: Includes an onboard voltage regulator and level shifter for safe operation with both 3.3V and 5V logic systems.
MODULE DESIGN: Compact breakout board with Molex PicoBlade connectors enabling easy wiring and solderless integration.
PIN CONFIGURATION: VCC – Power supply input, GND – Ground connection, SDA – I2C data line, SCL – I2C clock line, SDO – SPI/I2C address selection pin, CSB – Chip select pin for SPI communication.
APPLICATIONS: Widely used in weather stations, altitude measurement systems, drones, IoT environmental monitoring, navigation devices, and smart sensing applications.
