= Performance Notes =

For optimal performance, observe these guidelines:

  • Sampling Interval: Recommended 830 seconds between measurements to prevent selfheating
  • Power Decoupling: Use a 100nF capacitor between VCC and GND near the sensor
  • I2C Speed: Supports 100KHz to 400KHz bus speeds
  • Operating Range: Best performance at 20°C to +60°C, 1080% RH
  • Sensor Recovery: Prolonged exposure to >80% RH may cause temporary drift; sensor returns to calibration under normal conditions

= Safety Precautions =

Do not exceed 5.5V supply voltage
Protect from electrostatic discharge (ESD) during handling
Keep away from water and moisture
Avoid prolonged exposure to condensing environments
Handle with care - sensitive MEMS element
For outdoor applications, consider protective enclosure
Allow sensor to stabilize for accurate readings after power-up
