The invention belongs to the field of mobile phone design, and specifically provides a multifunctional intelligent mobile phone. The multifunctional intelligent mobile phone, apart from comprising the parts of a conventional intelligent mobile phone, further comprises an auxiliary processor, an infrared luminous tube, an infrared integrated receiving head, a violet diode, a laser tube, a temperature sensor, a humidity sensor, an ultraviolet sensor, a dust sensor and an infrared illumination tube. Through a series of sensors, a learning remote controller can be customized, the temperature, humidity, ultraviolet ray intensity and PM2.5 concentration in an environment can be measured, and such functions as ultraviolet currency detection, PPT currency detection, infrared shooting and the like can be used. The auxiliary processor is arranged at the direct control ends of the sensors, such that the complexity of a mobile phone processor is reduced. The multifunctional intelligent mobile phone is expanded on the basis of a conventional intelligent mobile phone, the function of the mobile phone is improved greatly, and the mobile phone is more practical. By means of the display and the processor of the mobile phone, the cost is low.
