The module also offers an analog output for detailed vibration analysis via any ADC, providing versatility for a wide range of applications. 2.Dual Output Functionality: With both TTL and analog signal outputs, this vibration sensor module delivers valuable flexibility in interfacing options. The TTL output indicates a clear high-level signal when a vibration is detected (light off), while the analog output allows for more nuanced readings of the vibration conditions. 3.High-Level Signal Indication: Ensure a clear response from your security or monitoring systems with the shake vibration sensor module's high-level output signal. The built-in LED indicator remains off when a vibration is detected, providing a visual cue for system status checks at a glance. 4.Broad Detection Range: The 801S vibration sensor switch alarm module offers non-directional vibration sensing, making it an ideal choice for a broad set of monitoring tasks, from theft-prevention systems to industrial machinery health checks, ensuring no vibration goes undetected. 5.Easy Installation Design: This analog output vibration sensor is designed with convenient mounting holes, allowing for flexible and secure installation in a variety of settings. The versatility of the mounting options makes it a breeze to incorporate into your existing systems.
