Digital sensor to measure actual atmospheric conditions: temperature from -40 °C to 85 °C, humidity from 0 to 100% Rh, and pressure from 300 hPa to 1100 hPa. The last value allows for indirect measurement of a height of up to 9.2 km with an average accuracy of 1 meter. The sensor communicates over I2C or SPI bus, pins are working with the voltage of 3.3 V but the I2C lines tolerate a higher value of up to 5 V. Sensor can be operated directly from the Arduino boards.

Specification:

  • Supply voltage: from 1.8 V to 3.3 V
  • Communication: I2C or SPI
  • Lines of the I2C bus tolerate the voltage of 5 V
  • Humidity:
    • Measuring range: 0% Rh to 100% Rh
    • Accuracy: 3% for the range from 20% Rh to 80% Rh
  • Temperature:
    • Measuring range: from - 40 °C to 85 °C
    • Accuracy: +/-1 °C
  • Pressure:
