该测控系统是以单片机为核心，配合sht11温湿度传感器，以及相关的光耦电路组成。可以接收和控制所测环境的温度和湿度。该装置的工作原理是由温湿度传感器得到测量信号，经电路转换为电信号，然后送到单片机进行数据处理，经软件分析处理后送显示装置，CPU根据检测到的温度和湿度结果，判断温度，湿度是否在界定的范围内，由此启动控制装置，并进行自动调节，直到温度和湿度达到标准范围之内为止。-The control system is a microcontroller as the core, with sht11 temperature and humidity sensors, as well as related optocoupler circuits. Can receive and control of environmental temperature and humidity measured. The working principle of the device is to be measured by the temperature and humidity sensor signal is converted to an electrical signal via the circuit, and then sent to microcontroller for data processing, analysis and processing by software evacuation display device, CPU based on the detected results of the temperature and humidity, judgment temperature , humidity within the defined range, thereby activating the control device and automatically adjust until the temperature and humidity within the range of up to standard so far.
