Remotely monitor device voltage

Monnit’s 0–200 VDC or 0–500 VAC sensors measure the voltage between two electrical points, such as batteries or other sensors and measure the reported voltage. Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts. If a monitored value rises or falls beyond user-set thresholds, an alert is sent via text, email, or call. Know when essential appliances are operative (helpful for remote locations or decentralized operations).

By connecting the leads on the Monnit Wireless Voltage Meter to the positive and negative terminals of another device, battery, or sensor, it can measure the DC voltage 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. Notifications can be set up through the online system to alert the user when certain thresholds have been met or exceeded.

Instant alerts, instant action

This sensor comes with an industrial battery included with the life of up to 7 years.

WARNING: Use caution when interfacing to the Monnit Wireless Voltage Meter. Negative voltages, AC Voltages, or DC Voltage exceeding maximum (as outlined in product specifications) WILL DAMAGE the electronics of the Monnit Wireless Sensor. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.

All industrial sensors are enclosed in a reliable, weatherproof NEMA-rated enclosure that are constructed for both indoor and outdoor use. These rugged enclosures protect the sensor circuitry against;

Falling dirt
Wind-blown dust
Rain, sleet, snow, splashing water, and hose-directed water
Ice formation on the enclosure
Increased resistance to corrosion

Monnit Gateway Options

An integral component of any IoT network is the gateway. A gateway device allows for data from sensors to be transmitted to the iMonnit software platform.

Monnit Ethernet Wireless Gateway 4

Monnit’s Ethernet Gateways allow your Monnit Wireless Sensors to communicate with the iMonnit™ Online Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the gateway into an open Ethernet network port with an internet connection. It will then automatically connect with our online servers, providing the perfect solution for commercial locations where there is an active internet connection.

Monnit 4G + Ethernet IoT Gateway

The ALTA® by Monnit Wireless IoT Gateway combines a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA Wireless Sensors. The ALTA IoT Gateway allows ALTA Sensors to operate on the world’s leading cellular networks and stay connected to the Internet. The gateway uses AC main power but also has redundant power through a battery backup lasting up to 60 hours.

To meet the global demand for enterprise IoT deployment, the IoT Gateway communicates with the cloud-based iMonnit® monitoring software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.
