The invention discloses a
urine and excrement detection sensor, a diaper and a
monitoring system. The
urine and excrement detection sensor is strip-shaped integrally, and comprises a first
electricity-conducting strip, a second
electricity-conducting strip and a third
electricity-conducting strip. The first electricity-conducting strip, the second electricity-conducting strip and the third electricity-conducting strip are arranged on a first substrate. A
misinformation through hole is formed in the middle of the second or third electricity-conducting strip, and an isolating layer covers the corresponding other electricity-conducting strip. The
misinformation through hole divides the corresponding electricity-conducting strip into two sections. The
misinformation through hole and the isolating layer divide the sensor into an excrement detection area and a
urine detection area. The urine and excrement detection sensor is arranged on a diaper body. The urine and excrement
monitoring system comprises the diaper and a smart terminal. The urine and excrement detection sensor, the diaper and the
monitoring system have the advantages that the isolating layer is arranged on the corresponding electricity-conducting strip of the urine and excrement detection sensor, a separation area is arranged in the middle of an absorption core layer to separate the excrement detection area from the urine detection area, and accordingly, urine and excrement detection misinformation is avoided; communication between a communication
triggering device and the smart terminal is realized through a
wireless communication module, and urine and excrement are prompted by the smart terminal.
