ky-024 hallsensor is too weak
Posted: 26 Nov 2022, 14:07
Hello
I am using a ky-024 hallsensor.
But the magnet in the gas meter is too weak to trigger the sensor (the distance too far, about 1.5 cm)
I have desoldered the sensor and added a cable to try all possible orientations with respect to the magnet. It is set to the most sensitive level. The sensor works with a normal magnet.
I also tried a high sensitivity reed contact with 10-20 AT , this only works about.90% as it also misses some pulses.
However, with the IPhone I can see the magnetic field (the change when magnet is passing and iPhone is hold to the meter).
Does anyone know a more sensitive magnetic field sensor to work on a ESP?
