** Developed for the Samsung Galaxy S4 and Samsung Galaxy Note 3, full compatibility is not guaranteed on other models ** ** models like Galaxy S3-S5 or Galaxy Note2-Note4 are missing temperature and humidity sensor, not my fault, sorry, the device manufacturer has decided to remove these sensors ** ** if a sensor is set as "NOT PRESENT" is because your phone doesn't have it ** functions:   - Ambient temperature in degrees celsius   - Percentage of moisture in the air   - Light intensity
