在導體上通過電流，並在垂直電流方向施以外加磁場時，電子會受到勞倫茲力（Lorentz force）擠壓到一端，進而產生微弱電壓，就是霍爾電壓 ( Hall Voltage )。

霍爾效應感測器( Hall Effect Sensor )的基本配置包含一個霍爾元件（將磁場轉換為電壓），以及運算放大器等處理電路。
霍爾感測元件感應磁場之後而得到的電壓是一種類比訊號，在霍爾感測器的內部，會經過施密特觸發器將訊號轉換成高或低的數位訊號來輸出，方便輸入到MCU的GPIO腳位做後續控制。

以下為實作的程式碼










void setup() {
pinMode(3, INPUT);
 Serial.begin(9600);
}

void loop() {
Serial.println(digitalRead(3));
 delay(10); 
}

已確認霍爾開關之磁力來源只受到測試磁鐵影響，且磁力可穿透壓克力防水護罩。
