Description

A remote baby bedwetting alarm

The invention relates to the technical field of electronic devices, in particular to a remote baby bedwetting alarm.

Background technique

Nowadays, people's work pace is very fast. Some young parents have no time and energy to take care of their babies, and at the same time they lack experience. Forgot to change the diaper in time when playing, or when going out to work, worrying that the nanny will not be able to find out and change the diaper for the baby in time. These problems will cause the baby's red buttocks, eczema, affect the baby's mental development, and form habitual bedwetting, etc.

Contents of the invention

Aiming at the defects of the background technology, the present invention proposes a remote baby bedwetting alarm, which can remind the adults to change the diaper for the baby in time when the baby wets the bed, without being limited by distance and location, ensuring the health of the baby and reducing the burden on the parents. Worry, and at the same time the circuit is simple, it will not cause harm to the baby's body, it is convenient and practical, and it is worth promoting.

In order to solve the above problems, the present invention adopts the following technical solutions:

A remote baby bed-wetting alarm, including a battery, a switch, a humidity sensor, an A/D converter, a single-chip microcomputer control circuit, a GSM module, a buzzer and a sensitivity adjustment knob, wherein the battery is connected to the switch, the switch is closed, and the battery is The entire circuit is powered, the single-chip control circuit is connected to the switch, GSM module, buzzer, sensitivity adjustment knob and A/D converter, the humidity sensor is connected to the A/D converter, and the humidity sensor transmits the signal to the A/D After the converter performs analog-to-digital conversion, it is sent to the single-chip microcomputer control circuit. After the single-chip microcomputer detects the humidity signal, it drives the buzzer to send out an alarm sound, and at the same time sends the signal to the GSM module, and sends a text message to the user's mobile phone through the GSM module. The sensitivity adjustment knob can adjust the system. sensitivity.

As a further optimization scheme of the remote baby bed-wetting alarm of the present invention, the material of the moisture sensitive sensor is a conductive film.

As a further optimized solution of the remote baby bed-wetting alarm of the present invention, the buzzer can play music.

As a further optimization scheme of the remote baby bed-wetting alarm of the present invention, the sound of the buzzer increases from low to high.

Compared with the prior art, the present invention adopts the above technical scheme and has the following technical effects:

First, the present invention has a simple structure, can be used in any place, and is easy to carry when going out;

Second, the single-chip microcomputer circuit is used for control, the control circuit is simple, and the reliability is high;

Third, the conductive film is used as a humidity sensor for detection, which is resistant to bending, high in sensitivity and good in safety;

Fourth, the user can be not only reminded by the sound of the buzzer, but also reminded by a short message to remind the adult to take care of the child in a timely manner, which is beneficial to the health of the baby.

Detailed ways

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

The invention provides a remote baby bedwetting alarm, as shown in Figure 1, comprising a battery, a switch, a humidity sensor, an A/D converter, a single-chip microcomputer control circuit, a GSM module, a buzzer and a sensitivity adjustment knob, wherein the battery Connected to the switch, the switch is closed, the battery supplies power to the whole circuit, the single-chip microcomputer control circuit is connected to the switch, GSM module, buzzer, sensitivity adjustment knob and A/D converter, and the humidity sensor is connected to the A/D converter. The sensitive sensor transmits the signal to the A/D converter for analog-to-digital conversion, and then transmits it to the single-chip microcomputer control circuit. After the single-chip microcomputer detects the humidity signal, it drives the buzzer to sound an alarm, and at the same time sends the signal to the GSM module, and sends a text message to The user's mobile phone, the sensitivity adjustment knob can adjust the system sensitivity.

The humidity sensor is made of conductive film material with good insulation, high mechanical strength, transparency and air tightness, which is especially resistant to bending and high elasticity. When used, it will not cause damage to the circuit due to multiple bending Damage; simple children's music is written in the single-chip control circuit program, and when the buzzer is driven, the sound will not frighten the baby from low to high.

The user presses the switch, the battery supplies power to the single-chip control circuit, and the single-chip control circuit enters a standby state after initialization.

If the baby wets the bed, the humidity sensor detects the humidity signal and outputs an analog signal. The analog signal is converted into a digital signal by the A/D converter and input to the single-chip control circuit. The single-chip control circuit judges whether the humidity exceeds the set value. If the humidity is not If the humidity exceeds the set value, the system will re-test; if the humidity exceeds the set value, the microcontroller control circuit will output a signal, on the one hand, the output signal will drive the buzzer to sound an alarm; on the other hand, the signal will be output to the GSM module, and the GSM module will pass the GSM (Global Mobile Communication system) The network sends a urine wet alarm signal to the predetermined mobile phone, prompting the parents to change the diaper in time, or the parents notify the nanny to change the diaper in time. The sensitivity adjustment knob is used to adjust the system sensitivity and change the critical value of the alarm according to actual requirements.
