The middle handle is shifted to one end of the two ends of the toggle switch, so that the middle handle can be connected with the end. The internal structure of toggle switches is well known and will be apparent to those skilled in the art. The invention relates to an application of a toggle switch, wherein one end of the toggle switch is respectively connected with the input end of a single chip microcomputer, and the other end of the toggle switch is commonly grounded. In the embodiment, flag bit 1 is set to on and flag bit 0 is set to off.
In the embodiment, the multi-channel quantity flag bit is a two-position toggle switch, 4 states exist according to whether the multi-channel quantity flag bit is connected with the ground or not (the connection is 1, and the disconnection is 0), and the single chip microcomputer distributes ports according to the number of 1-4 channels respectively according to 00, 01, 10 and 11. The toggle switches with different numbers of bits can realize different numbers of channels, and under the condition that the I/O of the singlechip is sufficient, the toggle switches with 3 or more bits can be adopted, for example, the toggle switches with 3 bits can realize 1-8 channels. According to the set number of channels, a temperature sensor circuit and a humidity sensor circuit are arranged in the urine wetness detection range of each infant, and the infant urine wetness alarm device is arranged in a public area nearest to a baby bed.
And/or the flag bit of the door control mode is a one-bit toggle switch, and 2 states, namely 0 and 1, are respectively corresponding to an AND gate and/or a door control according to whether the switch-on state is 1 and the switch-off state is 0 or not. And the AND gate control can provide the accuracy of detection, or the OR gate detection can provide the stability of detection, and can be selected according to actual needs. When the single chip microcomputer detects that the temperature sensor circuit and the humidity temperature sensor circuit are both high potential, the sound circuit and the light-emitting circuit of the corresponding channel connected with the output end are controlled to sound and emit light. When the door or gate is controlled, when the singlechip detects that one or both of the temperature sensor circuit and the humidity temperature sensor circuit are high potential, the singlechip controls the sound circuit and the light-emitting circuit of the corresponding channel connected with the output end to sound and emit light. When the infants who have different passageways simultaneously wet, singlechip appoints a music chip sound production, and luminous circuit is not influenced. Whether the control is the control of an AND gate or an OR gate, when the temperature sensor circuit and the humidity temperature sensor circuit are both in low potential after the diaper is replaced, the sound circuit of the corresponding channel is controlled to stop sounding and the light-emitting circuit is controlled to stop emitting light.

The connecting point of the thermistor and the resistor is connected with the base electrode of the triode, and the collector electrode of the triode is connected with the input end of the appointed port of the singlechip. The thermistor is divided into a positive temperature coefficient thermistor and a negative temperature coefficient thermistor, wherein the resistance value of the thermistor is increased when the temperature of the thermistor rises, and the resistance value of the thermistor is reduced when the temperature of the thermistor rises.

According to the set multi-channel quantity flag bit, and/or gate control mode flag bit, delay time flag bit and time-sharing detection time flag bit, the single chip microcomputer controls the sounding circuit and the light-emitting circuit which are connected with the output end to sound and emit light.
