介绍了一种基于IEEE802.15.4标准的全自主无线执行器节点(WEcoValve Mote)的设计。该系统允许远程控制(开启/关闭)3引线磁锁螺线管，通常用于农业地区、温室、花园等应用中的滴灌系统。系统的极低功耗与阀门的低功耗相结合，只有在切换位置时，才允许系统由太阳能供电，从而消除了对电线的需求，并促进了系统的部署。通过使用由专门设计的太阳能发电模块充电的超级电容器，还消除了更换电池的需要，系统完全自主，无需维护。“wEcoValve Mote”固件基于同步协议，允许双向通信，延迟针对实时工作进行了优化，节点之间的同步时间为4个S，从而实现了平均功耗2.9 mW。
The design of a fully autonomous and wireless actuator node ("wEcoValve mote") based on the IEEE 802.15.4 standard is presented. The system allows remote control (open/close) of a 3-lead magnetic latch solenoid, commonly used in drip irrigation systems in applications such as agricultural areas, greenhouses, gardens, etc. The very low power consumption of the system in conjunction with the low power consumption of the valve, only when switching positions, allows the system to be solar powered, thus eliminating the need of wires and facilitating its deployment. By using supercapacitors recharged from a specifically designed solar power module, the need to replace batteries is also eliminated and the system is completely autonomous and maintenance free. The "wEcoValve mote" firmware is based on a synchronous protocol that allows a bidirectional communication with a latency optimized for real-time work, with a synchronization time between nodes of 4 s, thus achieving a power consumption average of 2.9 mW.
