This experiment box used MSP430FG4618 as an embedded intellective controller, and DS18B20 as a temperature sensor. A SUNON fan and the heating resistor were used to regulate the temperature. The nRF24L01 and NetUSB 24L01 model were used to transmit data with wireless way. All above consist the automatic control experiment box system. The temperature control model of the experiment box adopted an improved Proportion Integration Differentiation(PID) arithmetic to regulate the temperature. Two parallel display methods (such as LCD and PC) were given, which met the need of various environment.
