Temperature and Pressure BME280 Sensor Module Voltage 1.71V - 3.6V Specification: This sensor is precision sensing solution for measuring barometric pressure and temperature with absolute accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! Excellent workmanship, convenient for you. I2C , SPI(4 wire), SPI(3 wire) interface. Very low noise - up to 0.2Pa(1.7cm) and 0.01 temperature, full calibrated. Type: Sensor Module Supply Voltage: 1.71V - 3.6V Max I2C Speed: 3.4Mhz Low Power Consumption: - 2.7uA at 1Hz Pressure Range: 300hPa to 1100hPa(+9000m to -500m) Size: 1.52cm x 1.20cm/0.60" x 0.47" (Approx.) Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
