Frequently Asked Questions

What is the operating voltage range for the HS-S20-L sensor module?

The HS-S20-L module operates from 3.3V to 5.5V DC. This range makes it directly compatible with both 3.3V logic systems (like ESP32 or Raspberry Pi) and standard 5V Arduino boards without requiring a level shifter.

How do I connect and use the digital (D/S) and analog (A/S) outputs?

Connect the V pin to your power supply (3.3V/5V), G to ground. The D/S pin provides a digital HIGH/LOW signal based on a preset light threshold. The A/S pin outputs a variable analog voltage proportional to light intensity, which can be read by an ADC pin on your microcontroller for precise measurement.

What type of connector does the module use, and how should I wire it?

The module uses a standard PH2.0 3-pin connector. The pinout is typically: V (power), G (ground), and the third pin is the signal output. You must check your specific module's labeling, as some versions may have separate D/S and A/S pins requiring connection to different microcontroller pins.
