Cheap waterproof ultrasonic sensor modules

That would be great,can you make the bus rate adjustable so it can support a number if different sonars.

The GL041MT sonar uses the same protocol, it just runs it at 115200.

The jsn sr04 uses the same protocol and 9600 baud

The ability to scale it would be ideal, it would let them operate underwater.

There are 2 operating modes, polling and auto, some sonars have it selectable but some are fixed due to being encapsulated.

There is a lua script here that will read it

Sonar JSN-SR04T

In order to read the sensor at maximum speed you would need read the serial stream directly from the sonar its self. currently there is no native serial driver but this is a serial lua driver that @Yuri_Rage created. its very fast but because the rangefinder is being read into lua but there is currently no lua binding for a rangefinder so it can only work within lua for actions and sending alerts and values it wont work with avoidance or anything like that currently. local SCRIPT_NAME …
