URM08-RS485 is DFRobot’s waterproof ultrasonic sensor for industrial and robotic controls. It measures distance and temperature, with built-in temperature compensation for high accuracy. The all-metal sealed case resists dust, water, and corrosion. It uses RS485 communication, supports Modbus protocol and cascaded control, ideal for liquid level monitoring or obstacle avoidance.

FAQ
Many ultrasonic sensors on the platform, how to choose?
It is recommended to refer to this selection guide.
Hi guys,
I am involved the project developing a pressure sensor using bmp388 and purchased the modules from here.
And have tested it with Pyboard, microphython and your library, bmp388.py.
Also, I have the bmp280 buying from you.
I have connected two different sensor boards with one pyboard.
The main.py works well and get the data from two sensors.
The problem is the pressure values are too different than expected.
BMP388's pressure data are higher more than 20 pascal which is too high on the ground. 1018~1019 would be ok in my environment.
I can't review all stuffs with your library.
PLZ advice to calibrate it.
You can see how I connected, the result and some main cord.
Best regards,
