Specific embodiment
The invention discloses a kind of water logging detector based on WiFi scheme, which can be used disposable lithium sub-
Battery power supply, whole system is mainly by leak water detdction circuit, edge sense circuit, AND gate circuit, WiFi main control chip, alarm electricity
Road and radio circuit composition.Wherein: leak water detdction circuit is connect with edge sense circuit, and edge sense circuit and AND gate circuit connect
It connects, AND gate circuit is connect with WiFi main control chip, and WiFi main control chip is connect with warning circuit, radio circuit respectively.
In the present invention, leak water detdction circuit be used to detect detector outside whether leak, and send water leakage to
Edge sense circuit;Edge sense circuit is used to the edge signal of water leakage being converted to pulse signal;AND gate circuit is used for
The pulse signal of edge sense circuit conversion and the counting spill over of the RTC timer are received, and input pulse is believed
Number and count spill over and do and calculate, and calculated result is sent to the reset control unit of WiFi main control chip.
When WiFi main control chip is under deep sleep mode, external leak wake-up signal or main control chip count internal overflow
Signal can wake up WiFi main control chip and enter normal operating conditions out.External water leakage believes edge by edge sense circuit
It number is converted to pulse signal and is sent into AND gate circuit, count spill over and be also fed into AND gate circuit, as long as the one of input AND gate circuit
There is low level pulse in road signal, will control input wake-up WiFi main control chip by resetting;After WiFi main control chip is waken up,
