KUS600B ultra low power consumption ultrasonic level sensor is designed for LPWAN networ cells.
Q1))How it can work as the low power consumption?
1: the sensor use the ultra low power consumption MSP430 MCU to save the power. MSP430 is the low power consumption, and also have the many level power management method. the mcu will go to sleep each time after measurement,
2, the mcu controll all the circuit to reduce the power such as the power supply of ultrasonic snesor, the ultrasound echo receiver circuit, the pulse emitter circuit.
the sensor have 3 kind of working mode
a）, always measure mode ,
b）, meausring and report on the command mode,
c）,ultra low power consumption mode.
a is the normal nomde, b is the clust mode for the application such as there is more than 1 sensor on the bus to measure the level or distand in a limited space to reduce the echo disturb.
Q2) How can I fech the measuring result by RS485 from the KUS600B ultra low power consumption ultrasonic level sensor?
1, the power supply should consider first, if the power supply can be controlled by the host ( another way the controller of KUS600B ultra low power consumption ultrasonic level sensor) , the sensor don't need working in ultra low power consumption mode. So the host can fetch the result by sent the inquiy command. if the host don't controll the sensor power supply, then the sensor will work in ultra low power consumption mode. and pre-code will be sent before send the inquiry command,
