Scigiene’s Wireless Gen 2 Dry Contact Sensor 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. Scigiene's wireless sensors are ideal for pharmaceutical, medical and other high tech applications where loss of data is unacceptable. These also have an amazing range of over 1200 ft. with 10 year battery life and can be remotely upgraded via network connections. These are truly the most advanced wireless sensors available.

| 1. The resistance between the conductive probe ends
  must be less than this to ensure detection.  2. The input of this sensor is passive. Never apply
  any voltage to the detection lead.  3. Operating and storage altitude without DC power
  supply is -30.48 to 9144 m (-100 to 30000 ft). | ||
