HC-SR505迷你小型人體感應模組 人體感應模迷你型人體感應開關

HC-SR505小型人體感應模塊是基於紅外線技術的自動控制產品,靈敏度高，可靠性強，超小體積，超低電壓工作模式。廣泛應用於各類自動感應電器設備,尤其是幹電池供電的自動控制產品。常見應用人體感應燈具, 人體感應玩具, 安防產品 , 工業自動化控制  , 自動感應電器設備 , 電池供電自動控制等

• HC-SR505 小型人體感應模塊是基於紅外線技術的自動控制產品
• 靈敏度高，可靠性強，超小體積，超低電壓工作模式。
• 廣泛應用於各類自動感應電器設備,尤其是乾電池供電的自動控制產品。
• 全自動感應:人進入其感應範圍則輸出高電平，人離開感應範圍則自動延時關閉高電平，輸出低電平。
• 可重複觸發方式：即感應輸出高電平後，在延時時間段內，如果有人體在其感應範圍活動，其輸出將一直保持高電平，直到人離開後才延時將高電平變為低電平（感應模塊檢測到人體的每一次活動後會自動順延一個延時時間段，並且以最後一次活動的時間為延時時間的起始點)。
• 工作電壓範圍寬：默認工作電壓 DC4.5V-20V。
• 微功耗:靜態電流<50 微安，特別適合乾電池供電
