采用婴儿报尿器可使婴儿尿布尿湿后得以及时更换,消除了婴儿感染尿布湿疹的隐患,对婴儿身心健康十分有益。电路如图,婴儿尿布尿湿后,A、B 间电阻由原来干燥状态的无穷大减小到数十千欧,与1M 电位器分压后触发音乐 IC 产生声光报警。电路简单新颖,采用(?)27mm 压电陶瓷蜂鸣片,声音并不太大以免夜晚影响母婴睡眠,且不会惊动婴儿一次性将尿 The use of baby newspaper urinary bladder diapers can be changed after the timely replacement of wet, eliminating the risk of infant infection of diaper eczema, the baby is very useful physical and mental health. Circuit shown in Figure, baby diapers after wetting, A, B resistance from the original state of dry infinite reduced to tens of thousands of Europe, and 1M potentiometer partial pressure trigger music IC sound and light alarm. The circuit is simple and novel, the use of (?) 27mm piezoelectric ceramic beep film, the sound is not too big to avoid affecting the mother and baby sleep at night, and will not disturb the baby once the urine
