基于无线通信技术的温室环境参数监测系统

摘要

Making use of STC89C52 MCU, DHT11 temperature and humidity sensor , BH1750 light sensor and nRF24 L01 wireless module as well as LCD 1602 and 12864 LCD modules , the wireless communication technology-supported detection system for greenhouse environment parameters was designed to implement multi -point acquisition of the greenhouse temperature , humidity and illumination parameters for transmission to the receiving terminal through the wireless module before to be sent to the PC so as to realize monitoring of the greenhouse temperature , humidity and light intensity .The matters like obvious error and low efficiency in man-ual control operation can be solved .%运用 STC89C52单片机、DHT11温/湿度传感器、BH1750光照传感器、nRF24L01无线模块、LCD1602液晶及12864液晶显示模块等器件，设计了基于无线通信技术的温室环境参数监测系统。该系统可以对温室内的温/湿度和光照参数进行多点采集，并将采集的温室参数通过无线模块送到终端（接收端），最后由终端设备将参数送至PC机。实现了对温室大棚中温度、湿度和光强的监控，解决了温室大棚人工控制测试的温/湿度误差大、费时费力及效率低等问题。
