检测运行时,由探头13检测信号,将信号传入接收窗口2中的中央处理器,中央处理器内的湿度检测电路开始运算,该湿度检测电路由第一三极管Q1、第二三极管Q2,第二电容C2、第三电容C3,第一电阻R1、第二电阻R2、第三电阻R3、第四电阻R4等共同组成了一个振荡电路。振荡频率由第六电阻R6来进行控制,第六电阻R6的一端接在探针P1的一根引线上,探针P1插入土壤里。随着土壤水分的变化,在探针P1上的电阻值也在发生着显著的变化,这个变化传导给第六电阻R6时,将使振荡电路的振荡频率发生变化。频率变化可通过连接在第二三极管Q2集电极的电流表PA的摆幅显示出来,人们再根据这个电流表PA的摆幅刻度来判断湿度的大小。
与现有技术相比,该用于农业生产的新型土壤湿度检测设备通过检测装置4中探头13插入土壤对土壤湿度进行检测,同时利用移动装置3中的第一驱动电机5和第二驱动电机6保证设备自由移动,从而实现设备对该区域进行全方位精确的检测;不仅如此,在湿度检测电路中,湿度检测电路中采用常规的元器件,在保证对湿度精确采集的同时,还降低了生产成本,提高了设备的实用价值。
