ALTA Wireless Voltage Detection - 500 VAC

The AC Voltage Detection Sensor notifies of the presence or absence of electricity. It is intended for use on devices using supply power from 24 - 500 VAC. Not intended for voltages higher than 500 VAC and also not intended for use with DC sources. Perfect for HVAC systems, sprinkler systems, sump pumps and any other type of electrical appliance monitoring. This sensor triggers on the state change from presence to absence of voltage and vice versa. The data is displayed as either "No Voltage" or "Voltage Detected".

ALTA - Leading Enterprise Grade "Internet of Things" Solutions

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.

  • Coin cell sensors typically last 3+ years.
  • AA and Industrial sensors typically last up to 12+ years.
ALTA products employ Monnit's new Encrypt-RF® Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.

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.
