Description

The HS-S21A tilt sensor module operates on a simple digital switching principle, changing its output state based on its orientation relative to gravity. This makes it ideal for basic tilt detection, anti-theft alarms, or position-sensing applications without the complexity of analog signal conditioning.

Its compact form factor and pre-drilled mounting holes allow for robust integration into prototypes or final enclosures. The module is designed for reliable performance across its specified voltage range, providing a clean digital signal compatible with most microcontrollers’ GPIO pins.

Key Features

  • Compact & Mountable Design: PCB dimensions of 36mm x 31mm x 18mm with 3.2mm mounting holes for secure fixture.
  • Simplified Digital Interface: Three-pin (GND, VCC, SIG) connection eliminates complex wiring and signal processing.
  • Broad Voltage Compatibility: Operates from 3.3V to 5.5V DC, supporting a wide range of development boards and logic levels.
  • Direct Microcontroller Integration: Digital output can be read directly by a GPIO pin, requiring no additional ADC circuitry.
  • Optimized Performance-to-Cost Ratio: Provides essential tilt detection functionality in a durable, ready-to-use module format.

Applications

  • Basic orientation detection in DIY robotics and RC models.
  • Tilt-activated security alarms or anti-theft devices for enclosures.
  • Simple position sensing in educational electronics kits and prototypes.
  • Leveling indicator for small-scale instrumentation or hobbyist projects.

Frequently Asked Questions

What is the output signal type of the HS-S21A sensor?

The HS-S21A provides a digital output signal on its 'S' pin. This means it outputs a logic HIGH or LOW voltage based on its tilt state, which can be read directly by a microcontroller's digital input pin without requiring an Analog-to-Digital Converter (ADC).

What is the operating voltage range for this tilt module?

The module operates from 3.3 volts to 5.5 volts DC. This wide range makes it directly compatible with both 3.3V systems (like Raspberry Pi, ESP32) and standard 5V systems (like most Arduino boards) without needing a logic level converter.

How do I mount and connect the HS-S21A sensor?

Mount the module using the two 3.2mm diameter holes spaced 10mm apart. For electrical connection, use the three labeled pins: Connect 'G' to ground, 'V' to your positive supply voltage (3.3V-5.5V), and 'S' to a digital input pin on your microcontroller to read the tilt status.
