Scigiene's Industrial Wireless Gen 2 dry contact sensors can be used to detect contact between two wired contact points. This sensor can be used with an external mechanical switch or a contact plate to alert the user via SMS text and/or email when the contacts touch or a switch is triggered.


  • Wireless range of 1,200+ feet through 12+ walls
  • Frequency-Hopping Spread Spectrum (FHSS)
  • Best-in-class interference immunity
  • Best-in-class power management for longer battery life
  • Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Data logs 2000 to 4000 readings if the gateway connection is lost (non-volatile flash, persists through the power cycle): 10-minute heartbeats = ~ 22 days, 2-hour heartbeats = ~ 266 days
  • Over-the-air updates (future-proof)
