Concrete meaning.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein (including technology art
Language and scientific term) there is meaning identical with the general understanding of the those of ordinary skill in fields.
For convenient for the understanding to embodiment, below in conjunction with being further explained explanation, and each embodiment not structure
The restriction of pairs of utility model embodiment.
Embodiment 1: as shown in Figure 1, a kind of instrument liquid-leakage preventing warning device, humidity sensor connects alarm, transmitter,
Transmitter connects router, and router is separately connected remote computer and mobile device.Humidity sensor has humidity sensor electric
Road.Humidity sensor circuit, alarm and transmitter are separately connected power supply.
Humidity sensor transmits data to alarm, transmitter, and transmitter transmits data to router, and router transmits number
According to remote computer and mobile device.
Or humidity sensor connects GPRS module, is transmitted to remote wireless terminal equipment by GPRS module.
As shown in Fig. 2, the humistor R1 of humidity sensor circuit is in parallel with first resistor R2, humistor R1 and first
One end of resistance R2 connects one end of capacitor C1,3rd resistor R4 and the 4th resistance R5, the other end ground connection of capacitor C1, wet sensitive electricity
Resistance R1 connect second resistance R3 with the other end of first resistor R2, and the other end of second resistance R3 connects the first incoming end (power supply
Anode), the other end of 3rd resistor R4 connects the second incoming end (test lead), the other end connection third access of the 4th resistance R5
It holds (power cathode), second resistance R3 is used to control humistor R1 charging.3rd resistor R4 is test mouth resistance, for electricity
Hold C1 electric discharge, the resistance for using resistance value ratio reference resistance and humistor all small is to accelerate the velocity of discharge.3rd resistor R4 is essence
Cipher telegram resistance.First resistor R2 for reducing humistor R1 Standard resistance range.
Humistor R1 places the bottom of instrument, and when there is liquid leakage, the liquid of leakage changes the shape of humistor R1
State, humistor R1 change in resistance issue signal by humidity sensor circuit, transmit data to router by transmitter,
Router transmits data to remote computer and mobile device.And signal is issued by humidity sensor circuit and touches alarm sudden strain of a muscle
Bright or sounding alarm.
As described above, being explained in detail to the embodiments of the present invention, as long as but essentially without disengaging
The inventive point and effect of the utility model can have many deformations, this is apparent to one skilled in the art
's.Therefore, such variation is also integrally incorporated within the protection scope of the utility model.
