Description

The Crowtail Collision Sensor 2.0 functions as a mechanical limit switch for robotic applications. In its default state, the module’s internal switch is open, outputting a logic high signal. Upon physical collision or impact, the switch is pressed closed, pulling the output pin to logic low. This provides a clear, immediate digital signal to a microcontroller for triggering evasive maneuvers, stopping routines, or logging collision events.

Designed for seamless integration into the Elecrow Crowtail ecosystem, the module connects directly to base boards without soldering. Its 3.3V to 5V operating range ensures compatibility with a wide array of development boards, from standard 5V Arduinos to 3.3V logic systems like ESP32 or Raspberry Pi Pico, making it a versatile component for prototyping mobile robots, automated guided vehicles (AGVs), and interactive installations.

Key Features

  • Digital Collision Detection: Provides a clean, debounced high/low TTL signal for reliable impact sensing.
  • Dual Voltage Operation: Supports a wide 3.3V to 5V DC supply range for flexible system integration.
  • Crowtail Interface: Utilizes the standardized 3-pin Crowtail connector for quick, solderless connection to compatible baseboards.
  • Compact & Lightweight Design: Features a small footprint and minimal weight, ideal for space-constrained mobile platforms.
  • Simple Integration: Requires only a single digital I/O pin on the host microcontroller for operation.
  • Durable Construction: Designed for repeated use in educational and prototyping environments.

Applications

  • Collision avoidance and bump detection for small mobile robots and rover platforms.
  • Limit sensing for 3D printer axes, CNC machines, or linear actuator endpoints.
  • Interactive art installations and exhibits requiring physical touch or impact detection.
  • Educational robotics kits for teaching sensor integration and basic autonomous navigation.
  • Simple security systems for detecting door/window contact or unauthorized movement.

Frequently Asked Questions

What is the output signal type of this collision sensor?

The sensor provides a simple digital output. It normally outputs a logic HIGH voltage (close to VCC). When a collision presses the internal switch, the output is pulled to logic LOW (ground). This signal can be read directly by a microcontroller's digital input pin.

Is this sensor compatible with 3.3V microcontrollers like the ESP32?

Yes. The module operates across a wide 3.3V to 5V DC range. You can power it from a 3.3V supply on an ESP32 or Raspberry Pi Pico, and its output logic levels will be compatible with the 3.3V logic of those boards.

How do I connect this sensor to an Arduino Uno?

Using a Crowtail base shield, simply plug the sensor's 3-pin connector into a digital port on the shield. If connecting directly, wire the module's VCC to Arduino 5V, GND to GND, and the signal (S) pin to any digital I/O pin (e.g., D2). Then read the pin's state in your sketch.
