What's the expected behavior of the Ultrasonic Sensor when no signal is returned? (i.e., angle of attack is 45 degrees or more) The original lego sensor spec says the device returns -1 when it doesn't…

The ultrasonic sensors help in measuring the distance, which will be used in this project to measure and water level and send the warning if it goes beyond the safe level. But the problem with ultraso…

Build a bulk of ultrasonic sensor :
- One for direction
- One for height
Both accessible via I2C (2 com wires)
The idea is to use an ATTiny as a I2C proxy.

### The problem
I am using jsn_sr04t in mode 1 (continous measurement via serial) to measure water level in tank.
Shortest measured range in my sensor is around 220mm but any measurement below 2…
