Check the listing for details. BMP280 BME280 High Precisn Digital Temperature Barometric Pressure Sensor Module. Condition: New. Listed at 2.45 USD. 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 BME280, the precision sensor from , is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface Specifications: Supply Voltage: 1.8 - 5V DC Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz) Operational Range: Temperature: -40 to +85°C Humidity: 0- Pressure: 300-1100 hPa Resolution: Temperature: 0.01°C Humidity: 0.008% Pressure: 0.18Pa Accuracy: Temperature: +-1°C Humidity: +-3% Pressure: +-1Pa I2C address SDO LOW : 0x76 SDO HIGH: 0x77
