A dry powder inhalation system having an inductor including a dry powder inhaler, an inductor, and an indicator light. The dry powder inhaler comprises a suction nozzle, a flow passage and a storage gate for storing the medicine, the suction nozzle has a gas guiding port and a suction port, the storage gate has a medicine discharging port, the flow channel is connected to the suction port and the medicine discharging port and has an initial position and a discharge position； The device is disposed adjacent to the air guiding port； the indicator light is disposed adjacent to the sensor and electrically connected to the sensor. When the user blows in air from the air guiding port, the medicine located at the medicine dispensing port enters the flow channel, and the medicine moves from the initial position to the discharge position, thereby discharging the medicine from the air guiding port, and the sensor senses the air. The control signal is sent to the indicator light to make the indicator light, and the user's medication status is known.一種具備感應器之乾粉吸入系統，其包括乾粉吸入器、感應器以及指示燈。乾粉吸入器包括吸嘴、流動通道以及貯存藥物的貯存閘，吸嘴具有導氣口以及吸入口，貯存閘具有出藥口，流動通道連接吸入口和出藥口並具有初始位置和排出位置； 感應器設置於鄰近導氣口之處；指示燈設置於鄰近感應器之處，並電性連接感應器。當使用者從導氣口吹入空氣時，以使位於出藥口的藥物進入流動通道內，並且藥物從初始位置移動至排出位置，進而使藥物從導氣口排出，而感應器感測到空氣之流動發出控制訊號至指示燈，使指示燈亮起，進而得知使用者的服藥狀況。
