Does anyone know how these sensors work, please?

They allow the computor on the collection vehicle to record the weight
of your bin contents.


If you don't want the council to know this info then just pass a
powerful magnet over the sensor.

Which is quite possibly an urban myth.....

Anyway, the reader on the bin lorry, would presumably register that the
sensor was faulty - and it'd be easy enough for replacement to be
arranged. Doing it every week might draw attention to yourself.
