Frequently Asked Questions

What is the operating voltage range for the TONYU DY-FPD204-6B/L3 sensor?

The sensor operates from 2.7V to 3.6V DC. This low-voltage range makes it directly compatible with common 3.3V logic systems found in microcontrollers like ESP32, STM32, and many Arduino boards, without requiring a level shifter.

What does the 540nm wavelength specification mean for this light sensor?

The 540nm value indicates the peak spectral sensitivity of the photodiode. This aligns closely with the human eye's maximum sensitivity in the green-yellow part of the visible spectrum, ensuring the sensor's readings correspond well to perceived brightness for natural automatic display adjustment.

How does the infrared filtering feature benefit the sensor's performance?

The integrated IR filter blocks or attenuates infrared wavelengths that are invisible to the human eye. This prevents sources like incandescent bulbs or sunlight from skewing the ambient light reading, resulting in more accurate and reliable visible light intensity measurement for display control algorithms.

Is this sensor suitable for surface-mount PCB assembly?

Yes, the 3mm plugin package is designed for through-hole PCB mounting. Its compact diameter allows for high-density placement on circuit boards within space-constrained devices like smartphones, tablets, and portable instrumentation.
