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


Due to high demand, we are working on a first come first serve basis. Contact us today to discuss how Technosphere can help you comply with social distancing
