传统的散热风扇存在噪音大、费电、只能靠人们手动控制且无法精确感知周围环

Traditional cooling fans have disadvantages such as high noise, power consumption, manual control by people, and inability to accurately sense the temperature of the surrounding environment. When people fall asleep, if there is no way to adjust the temperature of the fan in time, it will cause a cold. <br>In response to this problem, a design scheme for intelligent temperature-controlled fans based on solar power lithium iron phosphate battery storage is proposed: the system collects the temperature of the surrounding environment through a temperature sensor, converts the collected temperature into a temperature signal, and transmits the temperature signal to the microcontroller. , the single-chip microcomputer processes the temperature signal and outputs it to the display screen, displays the current temperature value on the display screen, calls the control function of the fan, and then controls the speed of the fan. When the measured temperature exceeds the set temperature threshold, the fan is at the highest speed; when the measured temperature is between the set temperature thresholds, the fan is at normal speed; when the measured temperature is lower than the set temperature threshold , the fan stops. The solar energy passes through the solar panel to charge the lithium battery, the lithium battery stores electricity, and supplies power to the system through the power generation booster module. The LCD1602 liquid crystal display screen dynamically refreshes and displays the temperature data collected by the DS18B20 temperature sensor in real time. The DS18B20 temperature sensor exchanges data with the single-chip microcomputer through a single bus. The temperature sensor is calculated by the single-chip computer program, and the fan is automatically turned on when the temperature exceeds the limit, and the cooling drive of the fan is realized, and the intelligent temperature control fan system is realized.
