It is a kind of can detect alternating current whether there is or not device.
Existing alternating current powers off the form that sensor is mostly wired, may be only available for the closer place of distance, remote to pass
Influence or cost when defeated due to the factors such as connect up, power are higher or cannot achieve.For case above, may be used wireless
The form of transmission, removes the trouble of wiring from, while reducing cost.But in power-off or some other, sensor
Electricity-fetching module cannot be complete machine power, although can use stand-by power supply, the operating power consumption of signal delivery module is higher, leads
Cause the signal under power blackout situation that cannot continue normally to send.And in the realistic case, sensor has been likely to increase other work(
Can, also will produce larger energy consumption, cause in the event of a power failure stand-by power supply exhaust quickly, the work for affecting sensor is held
Continuous property.
Utility model content
In order to solve problem above, the utility model devises a kind of novel Internet of Things power-off biography having compared with low energy consumption
Sensor, the energy avoided under power blackout situation is rapidly depleting, realizes the lasting normal work of sensor.
Specifically, the utility model uses following technical scheme：
A kind of Internet of Things power-off sensor, the sensor includes signal sending end and signal receiving end, signal sending end
Include for measuring whether tested cable maintains the electric module of survey of electricity, electricity-fetching module and use for obtaining electric energy from cable
In the signal transmitting module for sending measured signal, signal receiving end includes being sent for receiving signal transmitting module
Signal signal receiving module and signal picker, which is characterized in that in signal sending end, further include stand-by power supply module and
Circuit breaking controller part, wherein stand-by power supply module are powered when electricity-fetching module cannot obtain electric energy from cable for device, to real
