by The Leading Enterprise Internet of Things Solution Wireless 0-5 VDC Voltage Meters General Description Features of Monnit ALTA Sensors The ALTA Wireless Voltage Meter measures the voltage between two electrical points. It can be connected to the power and ground of any voltage source and measure within stated accuracy up to 5 VDC. It can be connected to any kind of variable voltage device, such as a transducer or sensor that outputs voltage. If the device to be measured is passive, the user must supply their own excitation voltage to the device. * * * * * Accurate to 3.0% full scale (FS) of voltage range * Accurate to 0.5% FS with user calibration * Interfaces with any variable-voltage device * 3 mV resolution Principle of Operation ALTA Wireless Voltage Meters read the voltage difference between two electrical points and reports back the measured voltage. It is programmed to sleep for a user-given time interval (heartbeat) and then wake up, convert the analog data, mathematically compute the voltage, and transmit the data to the gateway, where it is then logged into a cloud service. The user can configure defined thresholds and have the system alert on threshold breaches. Example Applications * * * * * * Battery health Voltage measurement Transducer measurement Machinery Electrical motors Many additional applications * * * * Wireless range of 1,200+ feet through 12+ walls * Frequency-Hopping Spread Spectrum (FHSS) Improved interference immunity Improved power management for longer battery life ** (12+ years on AA batteries) Encrypt-RF(R) Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages) Onboard data memory stores up to 512 readings per sensor: - 10-minute heartbeats = 3.5 days - 2-hour heartbeats = 42 days Over-the-air updates (future proof) Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email * Actual range may vary depending on environment. ** Battery life is determined by sensor reporting frequency and other variables.

Power Options The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0-3.6 V power supply. The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage. Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
