產(chǎn)品概述
此產(chǎn)品由一個(gè)電流感應(yīng)器TA12-200組成構(gòu)成??梢詫⒋蟮碾娏髁哭D(zhuǎn)換為幅度小的電壓量輸出。該模塊采用沉金工藝,外觀更加美觀,同時(shí)采用防插反3Pin接口,操作更加安全,插口一邊有大寫字母A表示該模塊位模擬量傳感器,另一邊是電流表的圖標(biāo)標(biāo)志表示該模塊具有測(cè)試電流的功能。此產(chǎn)品可以應(yīng)用于交流電的電流檢測(cè),最大可檢測(cè)的電流為5A。
規(guī)格參數(shù)
- 工作電壓 :+5v
- 尺寸大小: 30mm x 25mm
- 重量大?。?g
- 信號(hào)類型:模擬信號(hào)
引腳定義
- S:信號(hào)引腳
- NC:不需要連接
- -:電源地
使用方法
S引腳接到控制器的A0口。NC和 - 分別接到電源的+5V和GND。注:NC可以不接
應(yīng)用例程
示例程序
#define ELECTRICITY_SENSOR A0 // Analog input pin that sensor is attached to float amplitude_current; //amplitude current float effective_value; //effective current void setup() { Serial.begin(9600); pins_init(); } void loop() { int sensor_max; sensor_max = getMaxValue(); Serial.print("sensor_max = "); Serial.println(sensor_max); //the VCC on the RobotBase interface of the sensor is 5v amplitude_current=(float)sensor_max/1024*5/800*2000000; effective_value=amplitude_current/1.414;//minimum_current=1/1024*5/800*2000000/1.414=8.6(mA) //Only for sinusoidal alternating current Serial.println("The amplitude of the current is(in mA)"); Serial.println(amplitude_current,1);//Only one number after the decimal point Serial.println("The effective value of the current is(in mA)"); Serial.println(effective_value,1); } void pins_init() { pinMode(ELECTRICITY_SENSOR, INPUT); } /*Function: Sample for 1000ms and get the maximum value from the SIG pin*/ int getMaxValue() { int sensorValue; //value read from the sensor int sensorMax = 0; uint32_t start_time = millis(); while((millis()-start_time) < 1000)//sample for 1000ms { sensorValue = analogRead(ELECTRICITY_SENSOR); if (sensorValue > sensorMax) { /*record the maximum sensor value*/ sensorMax = sensorValue; } } return sensorMax; }
程序效果
打開串口監(jiān)視器之后,會(huì)輸出當(dāng)前檢測(cè)到的模擬值。
