Instructions:
Power Supply:
- Connect the VDD pin to a supply voltage between 1.7V and 3.6V.
- Ensure a stable power supply to avoid fluctuations that could affect sensor readings.
Ground Connection:
- Connect the GND pin to the ground of your system.
Analog Output:
- The VOUT pin provides an analog signal proportional to the measured humidity and temperature.
- Use an ADC (Analog-to-Digital Converter) to read the VOUT and convert it to digital values for processing.
Calibration:
- Calibrate the sensor using known reference points for temperature and humidity to ensure accurate readings.
- Refer to the datasheet for specific calibration procedures.
Operating Environment:
- Ensure the sensor is used within the specified temperature range (-40°C to 85°C) and humidity range (0% to 100%).
- Avoid exposing the sensor to extreme conditions or contaminants that could damage it.
Response Time:
- Allow the sensor sufficient time to stabilize before taking measurements, typically around 8 seconds to reach 63% of the final value.
Handling:
- Handle the sensor with care to avoid physical damage.
- Follow ESD (Electrostatic Discharge) precautions to prevent damage from static electricity.
Mounting:
- Mount the sensor on a PCB (Printed Circuit Board) using standard SMD (Surface Mount Device) techniques.
- Ensure proper soldering to maintain a reliable connection.
