A compost detection device is provided. A temperature sensor of the compost detection device is configured to detect a temperature of a compost. When the temperature is higher than a first predetermined temperature, higher than a second predetermined temperature, and lower than a third predetermined temperature, a controlling circuit records corresponding time and transmits corresponding messages to a remote device. The first predetermined temperature is higher than a room temperature, the second predetermined temperature is higher than the first predetermined temperature, and the third predetermined temperature is lower than the second predetermined temperature. Accordingly, a user can know a making status of the compost in real time.本新型提出一種堆肥偵測裝置。此堆肥裝置中的溫度感測器會取得堆肥的溫度,當此溫度大於第一預設溫度、大於第二預設溫度,以及小於第三預設溫度時,控制電路會記錄對應的時間並且傳送對應的訊息給遠端裝置。其中第一預設溫度大於室溫,第二預設溫度大於第一預設溫度,且第三預設溫度小於第二預設溫度。如此一來,使用者可以即時地知道堆肥的製作狀況。110‧‧‧堆肥偵測裝置120‧‧‧堆肥130‧‧‧遠端裝置142‧‧‧攪拌模組144‧‧‧氣體供應裝置146‧‧‧加濕器148‧‧‧濕度感測器150‧‧‧氧氣感測器152‧‧‧加熱模組
