ALTA wireless voltage meters are capable of measuring the voltage off another device battery or sensor. This sensor is capable of measuring voltage up to 500 VAC/VDC by connecting the leads on the sensor to the positive and ground terminals of the device being measured.

Examples of interfacing devices include but are not limited to: Strain Gauge Pressure Transducer RTD Thermistor or Thermocouple Piezo Electric sensors Photoresistor Industrial Accelerometer any kind of variable resistor any kind of sensor that outputs a voltage etc. If the device being measured is passive the user must supply their own excitation voltage as the Monnit sensor is really just a "voltage observer".

ALTA sensors offer 3 to 4 times the range of standard sensor platforms extending non-line-of-sight reach to an exceptional 1000+ 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 10+ 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.

Monnit ALTA Industrial Sensors come in an IP65 NEMA 4X CE rated sealed and weatherproof enclosure. They are powered by a single replaceable Industrial grade 3.6 V battery (included).

An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell the battery alone could continue to power the sensor for up to 8-10 years.
