IoT Fall Detection System Using MPU6050, ESP32, and Blynk

efy tested

This IoT Fall Detection System provides a proactive solution, ideal for those seeking to enhance the safety of loved ones or individuals at risk of falls.

Falls pose a serious risk, particularly for the elderly and those with medical conditions.

With this IoT-based fall detection system, instant notifications on a mobile phone can be received in the event of a fall. This enables a swift response, potentially preventing serious repercussions.
