Introduction
ANTARA is a wearable device for tracking social distancing between employees in factories, offices and public facilities. It sends real-time local alerts and records information on a server for reporting and contact tracing. This end-to-end IoT solution is designed for safety & security of people working in indoor commercial facilities in the post-Covid world.
ANTARA uses Bluetooth Low Energy (BLE), sensors and other technologies. Technosphere’s Gateway (ANTARAGA) complements Antara to send the information to server for Contact Tracing.
- For social distancing alert and contact tracing and Evacuation
- Haptic and LED alert
- Create a log of other wearable : ID , duration and distance of contact, Location
- Uploading the data to a cloud server through BLE gateway or a Mobile Phone
- Optional Temperature sensor to measure Body Temperature
- Location sensing feature for Hazardous area

- BLE Controller for Distance sensing & upload logs
- Haptic Feedback
- Li-Ion Rechargeable Battery
- Charging Circuit


- Device is a wearable to be worn on the wrist of the person to be monitored
- Device communicates with other wearables and the Gateways via BLE
- Maximum number of log items - 50
- Ability to configure the distance for sensing Social Distancing violation
- LED indication for Low Battery
- Device will monitors the following parameters
- Frequency of monitoring – once every second
- Proximity of other Wearable of same type within the configured range
- If violation, then Turn on the Haptic Feedback for 3 seconds
- Battery Life
- If battery voltage is low, sends different Haptic Feedback (eg: 1 second duration) – frequency to be every 5 minutes
- Device will send to Server through Gateway or Phone application
- Time Stamp when distance was violated
- Device ID which was near the wearable
- Battery Level
