Ultrasonic U098 Sensor Datasheet
-
Is there a datasheet for the U098 sensor chip? The website list RCWL-9600 as the chip. However, there is no schematic and no datasheet for this chip that I can find. There is some example code that show banging in some magic numbers via I2C and getting other magic numbers back as the response. However, that does not really help me in using it correctly.
Seems that at least there should be a list of available registers within the chip and their uses.
Thanks. -
@mrburns42, I can't help with the datasheet, I too failed to locate it.
But what I did manage to find is a library for a similar sensor, which allowed me to use the M5Stack ultrasonic sensor on I2C connected to a Micro:bit (with 5V carrier board and 3v3 to SCL and SDA). If you have look at the repo below there is a little more info on the address, byte size and data type and more, see SR04_I2C.ts file, which worked for me.
