Bengaluru: A technology enthusiast in Bengaluru has drawn widespread attention after developing a compact artificial intelligence-powered device designed to detect smoking in public spaces and trigger an audio response.
The innovation, shared by the developer on social media platform X, was created as a response to discomfort caused by exposure to public smoking. Instead of confronting individuals directly, the tech professional opted for a technology-based intervention.
Sharing details of the invention online, the developer wrote that the device plays pre-recorded audio alerts — including sounds such as a baby coughing and a reprimanding voice in the local language — whenever smoking is detected nearby.
How the Device Works
According to the explanation provided, the system uses artificial intelligence to identify individuals holding cigarettes and recognise smoking gestures in real time.
For its technical framework, the developer stated that the device integrates:
- YOLOv8 for object detection
- MediaPipe for gesture recognition
- Sarvam AI for generating audio alerts
The entire setup operates on a Raspberry Pi, making the device portable, compact, and practical for everyday use.
Plans for a Portable Version
The developer revealed that work is underway on a 3D-printed portable version, which may be released in the near future.
Images shared online showcased the Raspberry Pi configuration, detection screenshots, and demonstrations of how the device activates audio alerts upon identifying smokers.
Social Media Reactions
The project quickly gained traction online, particularly among users expressing frustration with public smoking.
Some users described the device as a potentially useful solution for enforcing no-smoking norms, especially in designated non-smoking areas.
Others emphasised that the conversation should focus on respecting shared public spaces rather than targeting smokers.
Technology Addressing Everyday Concerns
The device highlights how accessible AI tools and low-cost hardware can be applied to everyday social challenges. The project combines technology, behavioural awareness, and creative problem-solving.
