How the Swift Sensors wireless system works

This sensor pairs with a Swift Sensors Gateway (sold separately), which securely transmits encrypted readings to the Swift Sensors Cloud over Wi-Fi, Ethernet, Power-over-Ethernet, or cellular using 256-bit AES encryption. View live and historical data from any computer, tablet, or smartphone in the Swift Sensors Console, and set custom thresholds that trigger instant SMS text, email, and phone-call alerts.

  • Plug-and-play deployment — no wires to run and no software to install; sensors auto-pair with the gateway in minutes.
  • 6–8 year battery life from two replaceable AAA lithium-polymer batteries.
  • BLE5 wireless range up to 250–300 ft line-of-sight; each gateway supports up to 150 Series 3 sensors.
  • Secure, scalable cloud architecture — from a single sensor to thousands across multiple sites.
  • Two-year warranty and satisfaction guarantee. NIST-traceable calibration certificates available on temperature and humidity models.

Requires a Swift Sensors Gateway and an active Swift Sensors Cloud Monitoring plan. LabSupplies.com provides system-design assistance and dedicated account service for laboratories, healthcare, and facility teams.
