A small size wisdom device, which can be placed inside the diaper and detect diaper wet issue warning message, includes one electronic signal transmitter and one electronic signal receiver. The electronic signal transmitter consists of at least one wireless communication unit, one power unit, one current amplifier, one detecting wire pair, one glue cover, and one wire sleeve. If the current on the detecting wire pair is exist that determines the power unit supply power to the wireless communication unit for opening its wireless communication capabilities and issue warning message. The glue cover wraps on the wireless communication unit, the power supply unit, and the head portion of the detecting wire pair. Only the tail portion of the detecting wire pair exposed to the outside. The wire sleeve with two holes can insert the detecting wire pair that outside the electronic module for detecting specific feature. For example, when it is wet makes the current on the detecting wire pair, and on current when dry. The electronic signal receiver consists of at least one wireless communication unit, one power unit, one buzzer, and one glue cover.The power unit supplies power to the wireless communication unit for receiving signals, and the wireless communication unit will stimulate the buzzer when messages issued from the electronic signal transmitter was received.This creation of a wet diaper warning device is a combination of one electronic signal transmitter and one electronic signal receiver. The invention provides an easy to production and assembly, power-saving, light weight, easy to use, wisdom and safety the wet diapers warning device.一種小型可置於尿布內,用以偵測尿布尿濕發出信息的智慧裝置,包括一電子訊號發射模組,其至少有一無線通訊單元、一電源單元、一偵測線對、一電流放大電路、一包覆膠膜以及一導線套,該一偵測線對的導通電流經該一電流放大電路控制該一電源單元能否供電給該一無線通訊單元,產生無線通訊能力,並發出警示信息;該一包覆膠膜用以包裹該一無線通訊單元、該一電源單元、該一電流放大電路、該一偵測線對的線頭部分,僅該一偵測線對的線尾部分露出於外,該一導線套用以套入該一電子訊號發射模組中的該一偵測線對作為偵測潮濕,當其潮濕時令該一偵測線對上有導通電流流動,乾燥時則無導通電流;以及一電子訊號接收模組,其至少有一無線通訊單元、一電源單元、一警報器以及一包覆膠膜,該一電源單元供電給該一無線通訊單元,產生無線通訊
