0-5A Iteaduino AC Current Transformer Current Sensor Module With 3p 4p Interface

0-5A Iteaduino AC Current Transformer Current Sensor Module With 3p 4p Interface

Description:

Electronic brick of electricity sensor is based on TA12-100 current transformer, which can transform AC signals of large current into small amplitude signals. The maximum current that can be detected can reach 5A, and the present current signal can be read via analog I/O port.

Features:

1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.
3. PCB size: 30.0mm X 24.0mm X 1.6mm
4. Compatible interfaces: 2.54 3-pin interface and 4-pin Grove interface.

Example as follwing:



Note:

S for analog output port, G for ground, and N for not used pin.

Text code:

Link the S port of this sensor connect to A0 port of the board, use the following procedure to read analog values. And then display on the computer through the serial port.

#define ELECTRICITY_SENSOR A0 //
float amplitude_current; //
float effective_value; //
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 Grove interface of the sensor is 5v
amplitude_current=(float)sensor_max/1024*5/200*1000000;
effective_value=amplitude_current/1.414;
//Minimum current value can be detected=1/1024*5/200*1000000/1.414=24.4(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;

}
