GY-BMP280-3.3 Pressure Module

Description

GY-BMP280-3.3 Pressure Module The GY-BMP280 Barometer Sensor is a breakout board for Bosch BMP280 high-precision and low-power digital barometer. It can be used to measure temperature and atmospheric pressure accurately. It can be connected to a microcontroller with I2C GY-BMP280 Pinout: Pin No. Pin Name Pin Description 1 VCC Power source of 3.3VDC 2 GND Ground 3 SCL Serial Clock 4 SDA Serial Data 5 CSB CSB pin to GND to have SPI and to VCC(3.3V) for I2C. It’s an input to the chip. 6 SDO S erial D ata O ut / M aster I n S lave O ut pin, for data sent from the BMP280 to your processor Features: The GY-BMP280 module comes with BMP280 sensor , which is 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 accuracy Pin pitch: 2.54mm Module size: 11.5mm*15mm Specifications: Model: GY-BMP280-3.3 Chip: BMP280 Power supply: 3V/3.3V DC Peak current: 1.12mA Air pressure range : 300-1100hPa (equi. to +9000…-500m above sea level) Temperature range: -40 … +85 °C Digital interfaces: I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz) Current consumption of sensor BMP280: 2.7µA @ 1 Hz sampling rate Applications: Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection) Indoor navigation (floor detection, elevator detection) Outdoor navigation, leisure and sports applications Weather forecast, Home weather stations Health care application (e.g. sirometry) Vertical velocity indication (e.g. risk/sink speed) Handsets such as mobile phones, tablet PCs, GPS devices Flying toys Watches Package Includes: 1x GY-BMP280 Module Documents: Tutorial Datasheet Related Products: SENSORS | MODULES
