Diaper status monitor

A diaper status monitor for monitoring conditions of a diaper comprising:

• a gas sensing unit which includes at least one gas sensor for detecting a concentration of a target gas generated by feces or urine and generating an electrical signal indicating the concentration of the target gas;
• the target gas including ammonia (NH3) and hydrogen sulfide (H2S);
• an information output unit provided with at least one light emitting member;
• a microcontroller unit (MCU) electrically connected to the gas sensor of the gas sensing unit and the light emitting member of the information output unit;
• the MCU receiving the electrical signal indicating the concentration of the target gas and generating concentration data of the target gas;
• when the concentration of the target gas reaches a preset threshold value, the MCU outputting a status signal corresponding to the threshold value;
• according to the status signal, the MCU driving the light emitting member of the information output unit to emit light with a color corresponding to the status signal;
• a wireless communication module electrically connected to the MCU and used for sending the concentration data of the target gas and the status signal generated by the MCU to a receiving end;
• a battery unit electrically connected to the gas sensing unit, the information output unit, the MCU, and the wireless communication module for supplying power;
• a power switch electrically connected to the battery unit, the gas sensing unit, the information output unit, the MCU, and the wireless communication module and used for connecting or disconnecting the power supplied by the battery unit;
• and
• a housing provided with an inner cavity for mounting the gas sensing unit, the information output unit, the MCU, the wireless communication module, the battery unit, and the power switch;
• at least one insertion hole mounted to the housing for communicating the outside of the housing with the gas sensor;
• at least one connecting member arranged at an outer side of the housing for holding and fixing the housing on a preset position of the diaper.
