Aiming at the problems of complicated wiring,inconvenient installation and troublesome maintenance of the available barn environment monitoring systems, a design scheme of the barn environmental monitoring system based on nRF24L01 and IAP15W4K58S4 is proposed. nRF24L01 is a new wireless communication technology,with low power consump-tion,high transmission rate,low cost and so on,and can be directly connected with a variety of MCU. Its programming is sim-ple. IAP15W4K58S4 is a cost-effective microcontroller with powerful functions. The monitoring system is composed of the sensor node and the environmental monitoring node. The temperature,humidity and gas data detected by the sensor node are sent to the environmental monitoring node. The data processed by the environmental monitoring node are transmitted to the PC through a serial port for display. The practical test result shows that the system can run stably and can be used in the field of environ-mental monitoring.%针对目前粮仓环境监测系统存在布线繁琐、安装不便、维护麻烦等问题,提出了一种基于nRF24L01和IAP15W4K58S4的粮仓环境监测系统的设计方案.nRF24L01是一种新兴的无线通信技术,具有低功耗、高传输速率、低成本等特点,可直接与各种单片机连接使用,且编程简单;IAP15W4K58S4是一款高性价比单片机,价格便宜且功能强大.该监测系统由传感器节点和环境监测节点两部分构成,传感器节点将检测到的温度、湿度和气体等数据发送给环境监测节点,环境监测节点将这些数据处理后,经由串口传输给PC机来显示.经实际测试表明,该系统能稳定运行,并较好地应用于环境监测领域.
