GY-BME280 5V Temperature and Humidity Sensor

GY-BME280 5V Temperature and Humidity Sensor is an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of weather/environmental sensing and can even be used in I2C.

This precision sensor is the best low-cost sensing solution for measuring humidity with ±3% accuracy, 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 or better accuracy!

The BME280 is the next-generation of sensors and is the upgrade to the BMP085/BMP180/BMP183 – with a low altitude noise of 0.25m and the same fast conversion time. For simple easy wiring, go with I2C.

Features:

• The BME280 is a great new chip that was originally designed for the next generation of smartphones.
• With an I2C connection, you have access to enough weather data to make some pretty good predictions for your local area.
• BME280, the precision sensor, is soldered onto PCB.
• Not only the pressure and the temperature, but this sensor can also measure humidity.
• It uses both I2C and SPI (supports 3-, 4-wire SPI) interface
