[FAQ] OPT3001: What is the performance under flickering LED Light

OPT3001: What is the performance under flickering LED Light

Rene JAkob

Part Number: OPT3001


What is the rise and fall time of the OPT3001 sensor? Is it possible to measure PWM-pulsed LEDs with duty-ratio of 1% to 100% and pulse frequencies from 100 up to 1kHz?

Best regards,

René Jakob

    Hi Rene,

    The fastest conversion time on OPT3001 is 100ms so you will only get one reading approximately every 100ms. However, as is shown in the FAQ the PWM signal is correctly calculated with some error for 50% duty cycle. I believe this should work for the parameters you stated, but we have not tested this.

    Best,

    Alex
