Design of post-defecation detection reminder system based on single chip microcomputer
With the aging of population and the implementation of the three-child policy,the number of disabled elderly and newborns has increased greatly.The increase of these special groups has brought some troubles to themselves and their caregivers.This research aims at the problem of cleaning and nursing disabled elderly and newborn after defecation,and develops a detection system based on 51 MCU,which is mainly composed of four parts:control module,detection module,Bluetooth module and alarm module.Temperature and humidity sensor and hydrogen sulfide sensor are responsible for detecting defecation and defecation,MCU is responsible for data collection and processing,Bluetooth module realizes communication with mobile phone terminal,and after detecting defecation and defecation of the user,The alarm buzzer can remind the caregiver to help him clean after defecation in time,so as to avoid diseases such as incontinence related dermatitis caused by the failure of the user to clean in time after defecation.The system is unique in high precision,low cost,and easy to use.
