The utility model provides a wireless monitoring device for environmental parameters in a closet, which can measure the temperature, humidity parameters and air pollution degree of the closet in real time, and wirelessly transmit them to a computer terminal for real-time display. When the measured parameters exceed the set warning line , the computer sends out an alarm signal to remind the owner to handle or dry the clothes.

The utility model is realized by the following technical scheme: a wireless monitoring device for environmental parameters in a closet, including a host system and a sub-machine system, and the sub-machine system includes a sub-machine single-chip microcomputer, and a sub-machine wireless receiving and sending device connected to the sub-machine single-chip computer module, a temperature detection module, a humidity acquisition module, and an air pollution degree acquisition module connected to the sub-machine single-chip microcomputer, and a display module connected to the sub-computer single-chip microcomputer; the host system is placed in the computer room of the owner, including The host single-chip microcomputer module, the host wireless transceiver module and the computer terminal connected with the host single-chip microcomputer module; the host system and the slave system transmit data through the wireless transceiver module; the temperature detection module, the humidity acquisition module and the air pollution degree acquisition placed in the wardrobe The module collects on-site parameters, and converts the parameters into digital signals and transmits them to the sub-machine MCU for processing. After processing, the on-site parameters are displayed in the display module of the sub-machine, and the on-site parameters are transmitted to the host MCU of the host system through the wireless transceiver module for processing. The host microcontroller transmits the signal to the computer terminal through the serial port, and displays the environment inside the cabinet on the computer terminal. When the environment in the cabinet exceeds the set parameters, it will alarm and remind the owner to handle or dry the clothes.

The host single-chip microcomputer module is connected with a computer terminal through a serial port.

One or more subsystems are set as required.

The beneficial effect of the utility model is that not only the temperature, humidity and air pollution degree parameters of the wardrobe can be measured in real time, and wirelessly transmitted to the computer terminal for real-time display, when the measured parameters exceed the set warning line, the computer sends an alarm signal, Reminds the owner to dispose or dry the laundry. The utility model has the advantages of strong practicability, stable circuit, simple structure and low cost.

Detailed ways

As shown in Figure 1, the entire system is composed of a host system and a slave system, and one or more slave systems are set as required. The sub-machine system includes the sub-machine single-chip microcomputer, the sub-machine wireless receiving and sending module connected with the sub-machine single-chip microcomputer, the temperature detection module placed in the closet connected with the sub-machine single-chip microcomputer, the humidity collection module and the air pollution degree collection module, and the sub-machine A display module connected to the single-chip microcomputer; the host system is placed in the computer room of the owner, including the mainframe single-chip microcomputer module, the host wireless transceiver module connected with the mainframe single-chip microcomputer module and the computer terminal; the mainframe single-chip microcomputer module is connected with the computer terminal through a serial port. The host system and the slave system transmit data through the wireless transceiver module; the wireless transmitter module adopts NRF905. The temperature acquisition module is a DS18B20 temperature sensor, and the humidity acquisition module uses a DHT11 humidity sensor. The air pollution degree acquisition module uses the MQ-135 of the MQ series of semiconductor gas sensors.

The host computer system and the slave computer system work according to the main program flow chart shown in Fig. 2 and Fig. 3 . After power-on, the single-chip microcomputer of the neutron machine in Figure 1 collects the current temperature in the wardrobe through the temperature acquisition module DS18B20, collects the current humidity in the wardrobe through the humidity acquisition module DHT11, and collects the current air quality index in the wardrobe through the MQ-135 semiconductor gas sensor. The collected information is displayed in real time on the display module of the sub-machine shown in Fig. 1 . On the other hand, the single-chip microcomputer of the sub-computer starts the wireless transmission module NRF905 to work, and transmits the collected signals wirelessly. The MCU of the host in Figure 1 starts the wireless receiving module NRF905 to work, receives the wireless signal sent by the slave, and after decoding and identification, displays the received signal on the LCD module of the host in real time. In order to facilitate the owner's observation, the host computer is connected to the computer terminal through the serial port, and the management interface compiled by VB is used for real-time display. On the interface of Figure 4, the pink curve represents the temperature of distribution point 1, the green curve represents the temperature of distribution point 2, the black curve represents the humidity of distribution point 1, and the brown curve represents the humidity of distribution point 2. In addition, an alarm function is also set. If the upper limit of the temperature alarm is 15 degrees and the lower limit of the alarm is 10 degrees, and the temperature of point 1 is 23.2 degrees at this time, the alarm light will emit a red light alarm signal, and the computer will send out a beep alarm. Humidity alarm is the same principle. The air quality alarm adjusts the sensitivity adjustment potentiometer on the MQ-135 module to select a suitable alarm concentration, and an alarm will be issued according to the actual measured concentration on the operation interface.
