Description of Sensor Functions
There is 3 kinds of working mode,
1:Ultrasound normal measuring mode
The KUS550L ultra low power consumption ultrasound waterproof sensor will keep measuring for a determined period, the default period is 200ms, and the smallest period is around 25ms. The KUS550L ultra low power consumption ultrasound waterproof sensor will keep transmitting the ultrasound to measure the distance. this mode is usually used to measure when the application field ask quick response for the distance change. Or during the system adjustment and match. also the limitation of this mode is only 1 sensor for one place and direction, on the same RS485 bus.
2:ultrasonic standby measuring mode
The sensor will standby till the distance inquiry command sent from the host. The same to say, we can control the senor when and how to transmit ultrasound to measure, so it is very useful when there are more than 2 sensor in a limited space to measure the different direction and position. It’s very easy to use during this kind of application field, it’s acceptable for 254 sensor in one RS485 bus with the different address 0x01-0x254 .
3:Sleep and waken able for measuring mode
This is the lowest power consumption mode, the sensor will be sleep after power on, the sensor will be wakened up when there is high to low or low to high change on the RXD pin of the sensor, and the sensor will receive the UART frame to process. If the command is distance inquiry command the sensor will trigger a measuring and response to the host and then go to sleep. The sensor will keep wakened around 10ms, so the host must send 2 parts signals to the senor , lead code and then the Modbus-RTU command In 10 ms.
If the sensor is installed at the environment temperature fall below 0℃,It should do well on the protective measures. In case of direct mounting of the sensor in a through hole using the steel nuts, it has to be fixed at the middle of the housing thread.
