Part Number: DRV5032
I try to count the number of rotation of motor using DRV5032FADBZR sensor and atmega328p.
Sensor not detects the accurate count, gives me the wrong reading.
Rotation of the motor is 306 which I measured using digital tachometer but the hall sensor counts only 102 rotation.
Is there any option to get accurate result?
Thank you for using the TI forum. Please see a related thread here: https://e2e.ti.com/support/sensors/f/1023/t/781634
To sum up, latch devices are better suited for counting motor rotations (rotary encoding) than switches because the output state is held longer, and the DRV5032 does not have a very high bandwidth, which is probably why you are not counting all of the rotations.

In reply to Mitch M:
thanks for the reply but I still have confusion
Sampling rate of drv5032 is 20Hz that means it can detect 20 interrupts in one second, and according to my motor speed sensor need to detect maximum 6 count in one second,
Sensor has that capability then why it not count accurately?
Any help or suggestion would be appreciated
