The 801s Shake vibration Sensor Module is a compact, digital vibration detector designed for open source projects. It uses an LM393 comparator to generate a TTLlevel digital output when vibration or movement is detected, and it operates from a 35V DC supply. The opensource design supports easy integration and in hobbyist and educational deployments. Key benefits Simple digital interface: provides a clear on/off signal without the need for analog readings, simplifying microcontroller integration. Fast, reliable detection: intended for responsive vibration sensing in small form factor projects. Wide compatibility with common boards: designed for 35V logic and TTLstyle inputs, suitable for Arduino, ESP8266/ESP32, and other microcontroller platforms. Open source friendly: opensource LM393based design facilitates and rapid prototyping. Small and affordable: a compact module that fits easily into tight enclosures and budgetconscious projects. Key attributes Functionality: vibration/shake detection with a digital output using an LM393 comparator. Compatibility: operates at 35V DC; digital output compatible with TTL logic levels. Size and form: compact vibration sensor module suitable for hobbyist and educational use. Material and build: PCBbased module with standard electronic components centered around the LM393 comparator. Performance: delivers a digital signal when motion or vibration is detected, suitable for triggering logic in control systems. How it works and connections The module detects movement through its internal vibration sensor mechanism and produces a digital out signal via the LM393 comparator. Typical wiring: connect VCC to 35V DC, GND to ground, and OUT to a microcontroller input. Ensure a common ground between the module and the controller. The OUT line provides a TTLlevel digital signal; if your microcontroller input requires a pullup, add one as needed (many setups include it on the module). Use cases Security and alert systems: detect knocks, tampering, or movement on doors, windows, safes, or other protected enclosures to trigger alarms or notifications. Robotics and automation: sense motion or impacts in small robots, grippers, or automated assemblies to inform control logic or safety routines. Machinery monitoring and prototyping: monitor vibration events in motors, printers, or other equipment to flag abnormal activity or for experimentation in opensource projects.
