Problems solved by technology

[0002] Nowadays, people's work pace is very fast. Some young parents don't have the energy and experience to take care of their children. They don't know when their children are wet, or sometimes they forget to change their diapers in time when they go out to play, which will cause red buttocks, eczema, Affect the baby's mental development, form habitual bedwetting, etc.
[0003] In order to prevent parents from forgetting to change diapers for their children in time, some urine wetness alarm devices have been proposed, but the current urine wetness alarm devices are complex in structure, not easy to carry and popularize, and the devices are connected by wireless signals. On the one hand, the reliability is not high. On the other hand, wireless signals will have adverse effects on babies

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0018] Structural block diagram of the present invention is as figure 1 As shown, it includes manual switch, power module, humidity sensor, A / D converter, microcontroller control circuit, amplifier, speaker, LED light and sensitivity adjustment knob. The manual switch is connected to the power module to control the on-off of the power module. The power module is connected to the single-chip circuit to supply power to the whole device; the humidity sensor is connected to the single-chip circuit through the A / D converter, and the detected humidity value (analog ) is converted into a humidity value (digital quantity) by an A / D converter and sent to the microcontroller. The sensitivity adjustment knob is connected with the single-chip microcomputer circuit for setting the humidity alarm value; the single-chip microcomputer circuit is connected with th...

Abstract

The invention discloses a portable baby bed-wetting alarm, belonging to the field of electronic monitoring and alarm. The alarm comprises a manual switch, a power module, a moisture-sensitive sensor, an A/D (analog/digital) converter, a singlechip control circuit, an amplifier, a loudspeaker, an LED (light-emitting diode) lamp and a sensitivity adjusting knob, wherein the singlechip control circuit acquires humidity values detected by the moisture-sensitive sensor through the A/D converter, and automatically gives out sound and light alarms to remind parents of replacing a diaper when the detected humidity value exceeds a set alarm value. According to the invention, the moisture-sensitive sensor is sequentially connected with the A/D converter and the singlechip control circuit through signal lines, so that the reliability of the alarm is improved, and wireless signals are prevented from causing adverse effects to a baby. The portable baby bed-wetting alarm has a simple structure and is easy to carry.
