Social Distance App
Social Distancing is important to avoid highly contagious diseases. Prevention is the only way we can save us from these contagious diseases. According to our current knowledge flu viruses can spread person to person through personal contact or air (during coughing, sneezing or spitting). To avoid this expert suggest us to keep a distance minimum of 2 meter from each other which is known as social distancing.

What it does
The app is a solution which help the user to avoid close contact with the other user by maintaining selected (1-5) meter radius with the other user.

How it works
The app uses Bluetooth Smart that is Bluetooth Low Energy (BLE) beacon technology for detecting user in close proximity. It uses Android Beacon Library. The app continuously transmits and detects user low energy transmission and detection. Also the app works in the background supporting latest android versions.

IoT App to control and monitor remote PLC (Industruino)

This App is able to control your remote devices connected to Arduino over internet (using MQTT protocol).
We have tested with several MQTT server as broker like mosquitto, vernemq, cloudmqtt, hivemq etc. You can choose a server of your choice that follows MQTT should work the same.

The sensors and actuators configurations are read from a hosted configuration file that is in easily customisable JSON format.

The app creates the user interface Tab, Sensors and Controllers dynamically by reading the configuration file. The controller values can be adjusted from the UI dialogue box.

The actual Arduino devices used are as follows:
- Industruino D21G IND.I/O (https://industruino.com/)
- Industruino Ethernet Expansion Module
