Ultrasonic Level Sensor DF550 Datasheet LoRaWAN version

  • weight:1KG
  • Brand :CNDingtek
  • Model:72*72*115mm

The DF550 is ultrasonic level (distance )sensors which can measure the air height directly and calculate the liquid or solid height based on the total height of the container (distance).It is applicable for the close container or open container, or even the river. Furthermore it can calculate the volume of the container or the liquid. With LoRaWAN wireless module, the level data is sent to the network server via gateway. Finally user can monitor the realtime level remotely. It is optional for frequency 470Mhz(CN), 868Mhz (Europe), 915Mhz(USA), 915Mhz(Australia), 865Mhz(India),923Mhz(Australia).
