测试代码及使用手册

传感器内置稳压，支持3.3~5.5V宽电压工作环境，这意味着即使在3.3V的Arduino主控板上，它也能正常工作。标志DFRobot-Gravity接口保证了接口的兼容性，可以直GavityIO扩展板相连接。树莓派之类的微型PC，只需要外接一个ADC（模拟信号转数字信号）转换模块就产品工作电压3.3~5.5输出电压:0~3.0接口PH2.0-尺寸:98x23mm使用准准UNO控制板土壤湿度传感器PH2.0-3P接线ArduinoIDE接接线校校准代烧入校准代码至Arduino主控打开串口监视助voidvoidsetup()Serial.begin(9600);//openserialport,setthebaudrateto9600}voidloop(){intval;val= ogRead(0);//connectsensorto og0Serial.print(val);//printthevaluetoserial}校校准步打开串口监视器，将波特率根据程序设置为9600。此时读到的模拟100%湿度。（输出数据与湿度成反比，在水中的输出量最小）插入深度中读520，水中读数为260，这样就可以分为（520,430],(430,350],(350,260]这三个区间分别ThisexamplereadsCapacitiveSoilMoistureCreated2015-10-ByberinieChen>GNULesserGeneralPublicSee >forAllabovemustbeincludedinany/***********NoticeandTroubleshooting***************1.ConnectionandDiagramcanbefoundhere2.ThiscodeistestedonArduinoconstintAirValue=520;//youneedtochangethisvaluethatyouhadrecordedintheairconstintWaterValue=260;//youneedtochangethisvaluethatyouhadrecordedinthewaterintintervals=(AirValue-WaterValue)/3;intsoilMoistureValue=0;voidsetup()Serial.begin(9600);//openserialport,setthebaudrateto9600}voidloop()soilMoistureValue= ogRead(A0);//putSensorinsertintosoilif(soilMoistureValue>WaterValue&&soilMoistureValue<(WaterValue+{Serial.println("Very}elseif(soilMoistureValue>(WaterValue+intervals)&&soilMoistureValue<(AirValue-intervals)){}elseif(soilMoistureValue<AirValue&&soilMoistureValue>(AirVal
