Hey guys,
we have some issues with the TIDA 00489 PIR sensor design. We noticed, that during tests the sensor was heavily influenced by a dimmed LED ambient light. We are counting the movements in a room for 5 mins. If the LED light is on we counted approx 30000 movements which fits to the 100Hz frequency of the LED lamp.
Do you have any suggestion how to proceed?
I would prefer a hardware solution like a low pass filter, where would you position that one and do you think a RC-filter is enough and how we should dimension it? (50 Hz bulb frequency in europe and 100Hz up to 50kHz for LEDs)
kind regards
