Application Example:
Measuring Magnetic Field Strength
1.Components Needed:
•SS495A linear Hall sensor
•Power supply (e.g., 5V)
•Microcontroller or voltmeter
•Magnet
•Connecting wires
2.Wiring Diagram:
SS495A Sensor:
Vcc (Pin 1) -> +5V power supply
GND (Pin 2) -> Ground
Vout (Pin 3) -> Analog input of microcontroller or voltmeter
3.Setup:
•Connect the Vcc pin to the 5V power supply.
•Connect the GND pin to the ground.
•Connect the Vout pin to an analog input of a microcontroller or directly to a voltmeter to measure the output voltage.
4.Operation:
•Place a magnet near the sensor.
•The sensor will output a voltage proportional to the strength of the magnetic field.
•Read the output voltage using the microcontroller’s analog input or a voltmeter.
Example Code for Arduino:
const int hallPin = A0; // Analog pin connected to Vout of SS495A
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(hallPin); // Read the analog value
float voltage = sensorValue * (5.0 / 1023.0); // Convert the analog value to voltage
Serial.print(“Magnetic Field Strength (Voltage): “);
Serial.println(voltage);
delay(500);
}
Applications:
•Current Sensing: Measuring the current by detecting the magnetic field generated by the current flow.
•Position Sensing: Determining the position of a magnet or ferromagnetic object.
•Speed Sensing: Measuring the speed of rotating objects with magnetic encoding.
Precautions:
•Proper Calibration: Calibrate the sensor output for accurate measurements.
•Magnetic Interference: Avoid placing the sensor near other magnetic sources that could interfere with the readings.
•Stable Power Supply: Ensure a stable power supply to maintain consistent sensor performance.
