ALTA Wireless Dry Contact Sensor (AA)Monnit's ALTA wireless 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.

ALTA sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows ALTA sensors to have better interference immunity from other wireless devices.
Superior power management provides ALTA sensors with almost twice the battery life of Monnit's standard wireless sensors.
Integrated on-board data storage allows ALTA sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can't be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.
Over-the-air updates allow ALTA products to be updated remotely if new fixes or features become available.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
