摘要 灌溉问题是植物栽培中的重要问题。本文通过R-F(电阻-频率)转换电路实现了土壤湿度的连续、自动的测量。基于此方法,我们设计了1个依靠太阳能供电的自动浇灌系统,通过湿度仪的监控实现了浇灌的智能化。 Irrigation is a vital problem in plant cultivation.We measure the soil moisture by a Resistance-Frequency converter circuit.By this means,we design an automatic watering system which relies on solar power.It achieves the goal of intelligent irrigation by soil humidity monitoring instrument.
