I need some help with an SCA60C angle sensor not giving me the right output.
I am using Arduino Uno.
I have 5 volt and ground hooked up.
The Vo is tied to analog A0.
When I run Arduino test program:
When the sensor is Level the program gave me -104.
When I tilt it to the left I get -110 and does not change until tilted to 180 degrees.
When I tilt it to the right I get -54 at 90 degrees tilt and -110 at 180 degrees tilt.
const int anglePin =A0;
int angle =0;
const int angleCompensate =0;
void setup()
{
Serial.begin(9600); // setup serial
Serial.println("Electronic clinic SCA60C Angle Sensor");
}
void loop(){
getAngle();
Serial.print("Analog");
Serial.print(":");
Serial.print(angle);
Serial.print("°");
Serial.print(" ");
Serial.println(analogRead(A0));
delay(100);
}
void getAngle()
{
angle =map(analogRead(A0), 96, 927, -90, 90) + angleCompensate;
}
This program is from the web. If you search on “SCA60C and Arduino” this is the program
that a number of youtube and explanation websites use to explain the how the SCA60c works.
The program is supposed to work like this:
If you tilt it left 90 degrees, the program should read an angle of 90 degrees.
If you tilt it Right 90 degrees, the program should read an angle of 90 degrees.
If the module is set level the output should read an angle of 0 degrees.
The analogRead() was just to see what the sensor was outputing before the map().
