Hall Sensors Module for Arduino

Hall Sensors Module for Arduino

Product features:
1 working voltage: 3.3--5V
2 using 3144E switch type Holzer sensor.
3 when the sensor sensor to the magnetic field, the digital output low, the signal light is bright; if no induction to the magnetic field, then the digital output high level, the signal light is not bright.
4 with power indicator and signal indicator.
5 output mode: digital switching output (0 and 1) AO port is not valid
6 LM393 comparator output, model clean, good waveform, strong driving ability, more than 15mA.
7 Fixed bolt hole is provided, which is convenient for mounting and fixing.
8 can be used for motor speed, position detection, etc..
Sensor function introduction:
3144 Hall switch integrated circuit based on Hall effect principle, the use of manufacturing semiconductor integrated technology of magnetic sensing circuit, it is by voltage adjusting device, Hall voltage generator, differential amplifier, Schmitt trigger, temperature compensation circuit, and an open collector output stage is composed of a magnetic sensing detection circuit. The input for the magnetic induction intensity, the output is a digital voltage signal.

The sensor has the following characteristics: small size, high sensitivity, fast response, good temperature performance, high accuracy, high reliability.

Sketch

void setup() {
// put your setup code here, to run once:
pinMode( 7 , INPUT );
pinMode( 13, OUTPUT); // LED FOR TEST


digitalWrite(13,LOW);
}

void loop() {

// put your main code here, to run repeatedly:
if( digitalRead(7) == LOW ){
digitalWrite(13,HIGH);
}else{
digitalWrite(13,LOW);
}

Bro can u like give me the pin outs please, what is D0 and A0??
Also, there is no need to begin Serial communication in ```void setup(){}```
