HS-S22A Grayscale Sensor Module - 3.3-5.5V Digital Output
The HS-S22A Grayscale Sensor Module is a compact optical sensor designed for precise detection of surface reflectivity and grayscale levels. Operating on a 3.3-5.5V DC supply, it provides a digital output signal ideal for integration with microcontrollers like Arduino, ESP32, and Raspberry Pi for robotics and automation tasks.
Features
- High-precision grayscale detection via reflected light intensity measurement
- Wide operating voltage range of 3.3V to 5.5V DC for flexible system integration
- Fast digital output signal for real-time surface and line tracking applications
- Compact PCB design (31mm x 36mm) with standardized 2.54mm pin header interface
- Includes pre-drilled mounting holes (3.2mm aperture, 10mm spacing) for secure installation

The HS-S22A operates on a principle of active optical reflectance sensing. An integrated LED emits light onto a target surface, and a photodetector measures the intensity of the reflected light. This analog reading is internally conditioned and compared against a preset threshold to generate a clean digital output signal, enabling reliable discrimination between light and dark surfaces or varying shades of gray.
Engineered for stability, the module features a robust circuit design that minimizes noise and provides consistent performance across its specified voltage range. Its compact form factor and straightforward three-wire interface (VCC, GND, Signal) make it a practical choice for embedded systems, educational robotics platforms, and industrial automation prototypes requiring non-contact surface inspection.
