A detection system includes a G-sensor, a heartbeat detection module and a processing module. The G-sensor is configured for sensing the power generated by user activities to generate a gravity value. The heartbeat detection module is configured for detecting the heartbeat or the pulse of the user to generate a heartbeat value. The processing module is electrically connected with the G-sensor and the heartbeat detection module. The processing module is configured for generating a warning message when the gravity value is larger than a gravity threshold value, and the heartbeat value is larger than a first heartbeat threshold value or smaller than a second heartbeat threshold value.一種偵測系統,包含一重力感測器、一心跳偵測模組以及一處理模組。重力感測器用以感測使用者活動所產生之力量,並產生一重力數值。心跳偵測模組用以偵測使用者之心跳或脈博,並產生一心跳數值。處理模組與重力感測器以及心跳偵測模組電性連接。處理模組用以當重力數值大於一重力門檻數值,且心跳數值大於一第一心跳門檻數值或是小於一第二心跳門檻數值時,產生一警示訊息。200‧‧‧偵測系統110a‧‧‧重力感測器120a‧‧‧心跳偵測模組130a‧‧‧處理模組210‧‧‧體溫偵測模組
