Frequently Asked Questions

What is the operating voltage range for the HS-S38-L sensor?

The HS-S38-L module is designed to operate from a 3.3V or 5V DC power supply. Ensure your microcontroller or power source provides a stable voltage within this range. Connecting it to voltages outside this specification may damage the sensor.

How do I connect the HS-S38-L to an Arduino or Raspberry Pi?

Connect the module's PH2.0 connector pins: VCC to 3.3V or 5V, GND to ground, and the Signal pin to a digital input pin on your microcontroller. The sensor outputs a digital HIGH/LOW signal based on motion detection. No special communication protocol like I2C or SPI is required.

What does the sensor detect, and what is its response time?

This is a Passive Infrared (PIR) sensor specifically tuned to detect the heat signature and movement of a human body. Its response time is typically under one second, providing a quick digital signal change to trigger lights, alarms, or log events in your system upon detection.
