GY-BME280-3.3 High Precision Atmospheric Pressure Sensor Module BME280 for Arduino
The BME280 is an integrated environmental sensor developed specifically for mobile applications where size and low power consumption are key design constraints. The unit combines individual high linearity, and high accuracy sensors for pressure, humidity and temperature in an 8-pin metal-lid 2.5 x 2.5 x 0.93mm3 LGA package. The BME280 designed for low current consumption (3.6 µA @1Hz), long term stability, and high EMC robustness. The humidity sensor features an extremely fast response time which supports performance requirements for emerging applications such as: context awareness, and high accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor which features exceptionally high accuracy and resolution at very low noise.The integrated temperature sensor has been optimized for very low noise and high resolution. It is primarily used for temperature compensation of the pressure and humidity sensors, and can also be used for estimating ambient temperature.
The BME280 supports a full suite of operating modes which provides the flexibility to optimize the device for power consumption, resolution, and filter performance.
GY-BMP280-3.3 High Precision Atmospheric Pressure Sensor Module for Arduino
Bosch 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 from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuraccy, 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
