Abstract
The utility model discloses a kind of water sensor, comprise leak water detdction circuit and warning circuit, leak water detdction circuit design adopts LM393 voltage comparator as acp chip, LM393 voltage comparator and resistor network connect to form leak water detdction circuit, and leak water detdction circuit is connected with the warning circuit be made up of triode and hummer, and sensor can adopt battery or 5V DC power supply, detection probe interface reserved by sensor, power input interface, signal output interface, mounting-positioning holes.When probe has detected water leakage situation, can trigger buzzer warning and signal and export, this water sensor has and enriches interface, can be applied to multiple occasion, practical, is particularly useful in underwater robot pressurized capsule.
Description
Technical field
Key in technical field herein and describe paragraph.The utility model relates to sensor technical field, is a kind of by the sensor of hardware circuit realization to leak water detdction.
Background technology
At present, known relate to the place of water and situation a lot, also there are a lot of place, equipment etc. to need to carry out waterproof simultaneously, therefore very large demand is had to leak water detdction equipment, present leak water detdction device category is many, there is large-scale cluster detection system, be used in the small-sized sensor such as company, family, substantially all functionally detect leak and can report to the police, but lack compatibility and secondary development, cost is high, a lot of product be all be directly applied in specify place, environment, be not very flexible, interface is incomplete yet, should use limitation.
Utility model content
In order to solve subject matter and the deficiency of existing leak water detdction product, the utility model provides a kind of water sensor, and this sensor not only can detect water leakage situation and report to the police, and rich interface, compact, is particularly useful for leak water detdction in underwater robot pressurized capsule.
The utility model solves the technical scheme that its technical matters adopts: leak water detdction circuit design adopts LM393 voltage comparator as acp chip, LM393 voltage comparator and resistor network connect to form leak water detdction circuit, leak water detdction circuit is connected with the warning circuit be made up of triode and hummer, sensor can adopt battery or 5V DC power supply, detection probe interface reserved by sensor, power input interface, signal output interface, mounting-positioning holes.When probe has detected water leakage situation, buzzer warning and signal output can be triggered.
The beneficial effects of the utility model are, design realizes a kind of water sensor of pure hardware circuit, can detect water leakage situation and report to the police, having simultaneously and enrich interface, can be applied to multiple occasion, practical, is particularly useful in underwater robot pressurized capsule.

1. leak water detdction circuit, 2. warning circuit, 3. power interface, 4. signal output interface, 5. probe interface, 6. circuit board, 7. mounting-positioning holes, 8. agent structure in pressurized capsule, 9. water sensor in figure, 10. wire probe, 11. pressurized capsules.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, this example discloses a kind of water sensor, in FIG, leak water detdction circuit 1 is connected with warning circuit 2, power interface 3, signal output interface 4, probe interface 5 are connected with leak water detdction circuit, global design layout is on circuit board 6, and there is mounting-positioning holes 7 circuit board corner, and sensor can adopt battery or 5V DC power supply.Detection probe connects probe interface, and leak water detdction circuit 1 detects water leakage situation meeting trigger alarm circuit 2, and hummer rings, and signal output interface 4 exports high level alerting signal.The mounting-positioning holes 7 of this sensor circuit board may be used for sensor to be installed on distinct device.
Fig. 2 is that this exemplary application is in underwater robot pressurized capsule 11, water sensor 9 to be fixed in underwater robot pressurized capsule in agent structure 8 by mounting-positioning holes 7, wire to be popped one's head in 10 connecting circuit board probe interfaces 5, near parallel for the probe wire 10 hatchcover interface being fixed on pressurized capsule 11, the signal output interface 4 of water sensor 9 is connected with the control system of robot, can realize the detection to leaking in cabin like this.
Fig. 3 is the main circuit figure in this example, hummer and NPN triode form warning circuit, LM393 voltage comparator and resistor network form leak water detdction circuit 1, LM393 chip No. 1 pin output low level during normal condition, when probe place detect leak time, chip No. 2 pin input voltage changes, cause LM393 chip No. 1 pin to export high level, and then drive warning circuit 2 to work.
Claims (1)
