react-native-fall-detection-module

Fall Detection Library

When using a typical react native sensors library to try to detect a fall, we will need to set the update interval to < 100ms. However, this will cause the react native bridge to be overloaded. As such, the processing of the sensors data cannot be done in the React Native code. As a solution, this library will only send events through the react native bridge when a fall is detected.

Compatibility

Compatible with android only. If anyone would like to contribute to the IOS version of the code, please feel free to contribute to this project!

Installation

npm install react-native-fall-detection-module

Usage

import {
  FallDetectionEmitter,
  start,
} from 'react-native-fall-detection-module';
// ...

  const [data, setData] = React.useState<any | undefined>();

  React.useEffect(() => {
    start();
  }, []);

  React.useEffect(() => {
    FallDetectionEmitter.addListener('fall', (newData: any) => {
      console.log(newData);
      setData(newData);
      // put your data processing step here
    });
  }, []);

Data format being sent when a fall is detected is

{"detected" : true}

otherwise no data is being sent
