IR Proximity Sensor Touch less Door Bell:

How it works

An IR proximity sensor touches less doorbell works by using an infrared (IR) proximity sensor to detect objects or movement within a certain range.

This setup allows for a touch less interaction with the doorbell system, as it triggers the alert without requiring physical contact, making it convenient and hygienic, especially in scenarios where hands-free operation is desired.

Usages:

1. Home Entrances
2. Hygienic Environments
3. Security Systems
4. Smart Home Integration
5. Public Spaces
