Frequently Asked Questions

What is the operating voltage range for the Everlight Electronics ALS-PDIC243-3B sensor?

The Everlight Electronics ALS-PDIC243-3B ambient light sensor operates within a supply voltage range of 2.7V to 3.6V DC. This range makes it directly compatible with common 3.3V logic systems found in microcontrollers, IoT modules, and portable electronics without requiring additional voltage regulation.

What is the significance of the 540nm peak wavelength specification?

A peak wavelength of 540nm indicates the sensor's photodiode is most sensitive to green light, which closely aligns with the peak sensitivity of the human eye's photopic vision. This, combined with its integrated IR filter, allows the sensor to provide accurate ambient light readings that correlate well with human perception for applications like automatic display dimming.

How do I interface with this 5mm plugin ambient light sensor?

The ALS-PDIC243-3B is a plugin photodiode component, not a complete module with a digital interface. It requires external signal conditioning, typically involving a transimpedance amplifier (TIA) to convert its photocurrent output into a measurable voltage. This voltage can then be read by an MCU's ADC pin for light intensity analysis and control logic.
