HIH8131-021-001 Temperature-Humidity Sensor

SKU: BBV10000044

This board is used for humidity and temperature measurements and can transmit data digitally thanks to the I2C interface.If you solder JP1 and JP2, you can communicate with I2C. If you do not solder, you communicate with SPI.

Key Features

  • ±2.0 %RH accuracy (humidity performance)
  • ±0.5 °C accuracy (temperature performance)
  • Competitive humidity sensors require a 12 hour at 75 %RH rehydration process (which requires special equipment chambers) to correct reflow temperature offset.
  • Resolution : 14 bit ADC resolution
  • Response time : airflow minimum 20 l/min
  • Long term stability : 50 %RH for 5 years typ. ±0.05 %RH
  • Long term stability : 25 °C for 5 years typ. ±0.05 °C/yr
