Wheelchair Fall Detection DIY KitExperiments Science STEM KIT (Assembled), 100% Tested
Abstract
The Wheelchair Fall Detection DIY Kit is designed to enhance the safety of wheelchair users by detecting falls or unusual tilts. Utilizing a tilt vibration sensor and the LM393 comparator IC, the system triggers an alert when a significant tilt is detected, indicating a potential fall. This proactive approach ensures timely assistance and improves user safety.
Components Used
- Tilt Vibration Sensor: Detects changes in orientation or sudden movements.
- LM393 Comparator IC: Processes the sensor signals to determine significant tilts.
- Buzzer or LED Indicator: Provides audible or visual alerts upon detection.
- Power Supply: Operates on a standard 5V DC supply, suitable for USB power sources.
- Miscellaneous: Resistors, capacitors, PCB, and connectors for assembly.
Circuit Diagram
The circuit connects the tilt vibration sensor to the LM393 comparator. When the sensor detects a tilt beyond a predefined threshold, the LM393 outputs a signal to activate the buzzer or LED indicator, alerting caregivers or the user.
Conclusion
This DIY kit offers an affordable and effective solution for monitoring wheelchair stability. By promptly detecting falls or significant tilts, it enhances user safety and provides peace of mind for both users and caregivers.
