Frequently Asked Questions

What is the operating voltage range for the HS-S20L-B sensor?

The HS-S20L-B operates on a wide DC voltage range from 3.3V to 5.5V. This makes it directly compatible with common 3.3V logic platforms like ESP32 and Raspberry Pi, as well as standard 5V Arduino boards without requiring a level shifter.

How do I connect and use the analog and digital outputs?

The module has separate pins for analog (A/S) and digital (D/S) output. Connect the A/S pin to an ADC input on your microcontroller for a variable voltage proportional to light intensity. The D/S pin provides a high/low signal based on a preset light threshold, useful for simple on/off control. Always connect GND and VCC (3.3-5.5V) to the corresponding pins.

What type of connector does this sensor use, and is it included?

The module uses a standard PH2.0 3-pin female connector. The sensor is supplied as a standalone module; you will need to provide a compatible PH2.0 3-pin male cable or header to connect it to your system. This connector type is common in prototyping for its secure connection.
