ALTA wireless pressure meters measure pressure and transmit the pressure measurement to iMonnit. By connecting the Monnit wireless pressure meter to a pressurized gas, liquid or vapor supply line, it can measure the pressure within the line and send data to the iMonnit Online Sensor Monitoring and Notification System. The data is stored in the online system and can be reviewed and exported as a data sheet or graph. User customization allows you
to set notifications and alerts from the system so you can know immediately if pressure is above or below an optimal range.
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. Monnit's AA sensors have a battery
life that typically lasts 10+ years.
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.
