<![CDATA[TF sensor get always the same value]]>Hi folks

I have a program that reads the TF sensor every second.
After 1 or 2 weeks, the sensor suddenly only delivers the same constant value (last value read from it).
I have to restart the whole device and then the sensor does read out correct current values again for 1 or 2 weeks.

example (values only to visualize with some fault measurement like in real):
99.7, 99.6, 99.7, 98.9, 98.8, 98.5, 98.3, 98.4, 98.3, 97.9, 97.6, 97.2, 97.3, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7, 96.7

Does anyone know the problem?

Best regards
Thomas

Could it be that memory is filling up and not getting cleared out?

Does no one use the TF-sensor for such "long" time without restart?

The TF-sensor readings "hangs" exactly after 13 days.
After that always the same value is given out.
This behavior was occured every 13 days in the last 5 months.
Very strange.
What could that be?
