Monnit’s 0-20 mA Current Meter is capable of measuring the current off another device or sensor up to 20mA DC. This sensor is a staple in R&D departments, academic labs, healthcare settings, and other areas that rely on industrial and/or scientific sensors.

Users routinely interface Monnit’s Wireless Current Meters with pH sensors, magnetic flow meters, dissolved oxygen or pressure sensors, velocity or acceleration sensors, industrial vibration sensors, and industrial accelerometers. If the current deviates from user-set limits, Monnit’s sensor instantly alerts designated personnel via email, call, or text.

By connecting the leads on the 0-20 mA Current Meter to the positive and ground terminals of another device, the sensor can measure the current 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.

This sensor come standard with two replaceable AA batteries. The typical battery life is approximately 10 years.

WARNING: Use caution when interfacing to the Monnit 0-20mA Current meter. Negative voltages, AC Voltages , or DC Voltage exceeding 3.6V CAN DAMAGE the electronics of the wireless sensor. OneTemp is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.

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.

Online Sensor Monitoring Software

iMonnit is a cloud based mobile internet platform and central hub for managing Monnit and ALTA products. All data is secured on dedicated servers operating Microsoft SQL Server. This online user interface is where all your device settings can be arranged, supervised, and modified to reflect your unique environment. OneTemp will look after the activation and setup of your new online iMonnit account free of charge. There is also a free mobile app for you to stay in control at all times. Start with the basic version or upgrade to iMonnit Premiere to enjoy the full features your Monnit experience can offer.


iMonnit Basic Vs Premiere:

  • Basic - Free with no ongoing costs
    Monnit Basic is included for free with all wireless sensors, providing basic features for you to configure and monitor your sensors online. These basic features only support one network and one registered user on an account.
  • Premiere - Minimal Annual Fee
    iMonnit Premiere allows for enhanced functionality of your wireless sensors and includes an advanced software feature set at a low annual cost. All of iMonnit's advanced features are availble for configuration. You can have more sensors on your account, support multiple users, and view floorplans for all your sensors.
