无线大棚温湿度监控系统设计

摘要

In order to solve the problem of the greenhouse complex wiring,a kind of multi - point temperature and humidity acquistion system based on wireless transmission is designed in this paper. This system adopts STC89C52 single - chip computer as core control chip,DS18B20 digital temperature sensor and DHT11 humidity sensor acquisition the temperature and humidity signal,the wireless datatransceiver nRF24L01 was used to communicate between terminal mode and MUC,and sent to the LCD throught MCU.Which can retal-time monitor the temperature and humidity in the greenhouse. Result show that the system with features of high practicability and high reliablity,cost and low power,will be widely used in the future.%为了解决温室内的复杂布线等问题，设计一种基于无线通信的多点温湿度采集系统。采用STC89C52RC作为控制芯片，通过DS18B20数字传感器和DHT11温湿度传感器采集温湿度信号，通过nRF24L01无线收发模块与MCU通信，经过MCU处理后传送至液晶显示屏，从而实现温室大棚的是温湿度实时监测。研究表明，该系统具有较高的实用性和可靠性，功耗低，具有良好的应用前景。
