Use Monnits ALTA temperature monitoring solutions anywhere changes will degrade performance, assets, or safety. If temps rise or fall, get an alert via email, text, or call to step in and protect business.
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 Monnits standard wireless sensors.
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 cant 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. The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries.
Features:
- Automated data logging: ideal in pharma, food service & production.
- 25-month NIST Certification: this option helps ensure regulatory compliance.
- Plug-&-play simplicity: install within 15 minutes.
- Wireless range of 1,200+ feet through 12+ walls (Actual range may vary)
- Frequency-Hopping Spread Spectrum (FHSS)
- Improved interference immunity
- Improved power management for longer battery life (12+ years on AA batteries, maybe shorter depending on data logging configurations used)
- Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
- Datalogs 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power cycle): 10-minute heartbeats = around 22 days. 2-hour heartbeats = around 266 days
