Instructions

1. Power Supply: Connect the HI2002 sensor to a power supply within the range of 1.8V to 5.5V.
2. I2C Communication: Ensure that the device is connected via I2C bus with appropriate pull-up resistors on SDA and SCL lines.
3. Initialization: Upon powering up, initialize the sensor by sending the correct command sequence as specified in the datasheet.
4. Configuration: Set the desired resolution for both temperature and humidity readings.
5. Data Acquisition: Read the data from the sensor using the I2C protocol. The sensor provides digital outputs for both temperature and humidity.
6. Calibration: For higher accuracy, calibrate the sensor according to environmental conditions or use calibration coefficients provided by the manufacturer.
7. Handling Precautions: Avoid exposing the sensor to condensing conditions or environments beyond its operating temperature range to ensure longevity and accuracy.
