Mobile communication device and method for using the same

A mobile communication device, comprising:

• a communication unit for communicating with other communication devices;
• a processor unit connected to the communication unit;
• and
• a sensor unit connected to the processor unit, the sensor unit including at least one of a humidity sensor and a temperature sensor;
• wherein the humidity sensor senses ambient moisture and generates an electronic signal corresponding to the ambient moisture, and the temperature sensor measures ambient temperature and generates an electric signal corresponding to the ambient temperature;
• the processor unit calculating at least one of the ambient humidity and ambient temperature according to the electric signals and transmitting associated data of the sensor unit to the communication unit, the communication unit sending the data to other communication devices capable of communicating with the mobile communication device;
• wherein the communication unit includes a radio frequency (RF) module connected to the processor unit and an antenna connected to the RF module;
• when the mobile communication device sends signals, the RF module converts digital signals sent from the processor unit to radio signals, and the antenna sends the radio signals;
• when the mobile communication device receives radio signals using the antenna, the RF module converts the radio signals to digital signals.
