摘要
为了实现温室中的温湿度智能监测,本文设计了一款以PIC18F25K20嵌入式微控制器单片机作为上位机,以AM2302温湿度传感器作为下位机,采用EDA虚拟仿真技术对电路进行了仿真,实现了温湿度值的采集和实时显示;通过图表仿真技术捕捉到AM2302的时序图,分析时序图验证了AM2303传感器的单总线通信协议算法。在实际实验中,该电路实现了温室温湿度实时采集与显示,该电路还具有成本低、功耗小,性能稳定等特点,在实际应用可以用干电池或者太阳能作为电源。
In order to realize intelligent monitoring of the temperature and humidity in the greenhouse, the paper presents a humidity and temperature acquisition system. The system includes a microcontroller which is based on an embedded microcontroller PIC18F25K20 as a host and AM2302 humidity and temperature sensor as a slave. By using the EDA virtual simulation technology to simulate the circuit, and realize the collection of data of temperature and humidity is realized and real-time displayed. The advanced simulation technology is used to capture sequence diagram of AM2302 sensor, and timing diagram analysis is used to verify the AM2303 sensor single and bus communication protocol. The circuit is with low cost, low-power consumption and high stability performance. In real application, it can use dry batteries or solar energy as a power source
