Wireless AC Current Meters

Monnit's Wireless AC Current Meters measure the RMS current of an alternating current (AC) system by using a current transformer that wraps around the "hot" wire of a two wire (hot, common, ground (optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the iMonnit system. The iMonnit system is capable of generating watt hour or kilowatt hour readings as well.

Features of Monnit Wireless AC Current Meters:

    • Measures amp hours, max RMS current, min RMS current, and
      average RMS current.
    • 0-20 Amp and 0-150 Amp current transducers available.
    • Can track Watt our or Kilowatt Hour readings using iMonnit.
    • Data logging for accumulated amp hour readings.
    • Can notify based on current levels or changes in current levels.
    • Simple and safe installation of current/power measurement
      hardware, no rewiring required.
    • Free and premium online monitoring with alerts via SMS text,
      email or voice call

New Local Alert for Wireless Sensors

Monnit is excited to introduce a new Local Alert for Monnit wireless sensor networks. The Local Alert provides an additional way to receive critical notifications and sensor readings through your iMonnit network. When choosing to send a notification to the Local Alert, the user can choose what the device should do when it receives the notification. A notification can be programmed to flash the LED light, sound an audible alarm, display text on the LCD screen, or any combination of these features. The Local Alert can also be used to display sensor readings from any sensor on the same account.

Features of Monnit Wireless Local Alert:

    • Provides audible and visual alerts for wireless sensor notifications.
    • Three Alarm Types: Flashing red LED, buzzer, and message display.
    • LCD displays device name, custom message or sensor reading,
      and time of notification/reading.
    • Stores up to 10 notifications/readings.
    • Configurable alarm and snooze intervals.
    • Power saving features to extend battery life.
    • And much more...

Let's take a look in our crystal ball to see what the future holds at Monnit

Monnit's development team is always hard at work developing new wireless sensing products and enhancing our existing products based on customer feedback. We are currently working on a new food grade wireless temperature probe. The food temperature probe will be able to take temperature readings at set intervals and send that data to the online software where it can be viewed through the web dashboard, or in the mobile app. Alerts can be sent when the temperature of the food being prepared has reached it's optimal range. If you would like to learn more about the new food grade wireless temperature probe or be notified when it becomes available, please email us at sales@monnit.com.

Using wireless sensors to monitor pharmaceutical refrigerators.

With Monnit wireless sensors you can ensure that medications, vaccines and other pharmaceutical products have been maintained under recommended storage temperatures. It can be expensive if a pharmaceutical refrigerator fails but Monnit provides the solution.

With Monnit Wireless Sensors you can have 24/7 monitoring of your refrigeration units and be notified immediately if there is an issue. The monitoring system will also track temperature data for you and provide a detailed report as well as spreadsheet export functionality. Enjoy the peace of mind that comes from using Monnit wireless sensors to help manage your pharmacy.

Monnit provides a low-cost, reliable, wireless monitoring solution that allows you to track conditions and receive alerts for the following types of applications:

All Monnit wireless sensors come with free basic online monitoring, allowing you to view sensor information anytime from anywhere. Receive instant notifications via email or SMS text if a set sensor condition is met or exceeded.

Ensure your medications and vaccines are stored within regulated temperatures!

Wireless Sensor Installation for
Cooler Monitoring

This tech-tip is meant to give to give some suggestions for installing wireless sensors for applications involving walk-in coolers or freezers. For product documentation and additional help visit www.monnit.com/support.

Monnit wireless sensors communicate via RF (radio frequency) and it is important to note that the metal construction of most coolers and freezers can interfere with radio signal. It is also important to note that the temperatures inside of coolers and freezers can often be below the recommended operating temperature of the batteries used in Monnit wireless sensors. Due to these facts we recommend installing the wireless sensors outside of the walk-in cooler to ensure proper operation.

Wireless Temperature Sensor Installation

To install wireless temperature sensors, we recommend mounting the sensor just outside the door and running the sensor probe through the door seal or cooler wall. Alternately for temporary use, you can run the probe wire over the door seal but this will not allow for a tight door seal. To install through the seal or cooler wall, start by drilling a hole just larger than the size of the temperature probe in the seal or wall. Push the temperature probe through the hole and use clips or twist ties to secure the probe wire to the interior wall or shelving. When you have the sensor mounted outside and the probe ran to its desired location, use silicone caulking to seal the hole around the wire.

To prevent false notifications in the cooler we also recommend using a capsule containing a substance that will slow the heating and cooling of the temperature probe. This will allow the probe to report temperatures consistent with the contents of the cooler verses any immediate introduction of warm air when the cooler door is opened.



Wireless Door Sensor Installation

To install a wireless open/closed sensor on the door of a walk-in cooler or freezer simply mount the sensor, using the included screws or double sided tape, just above the cooler door. Next you will need to attach the sensing element (screws or double sided tape) to the door frame as close to the door as possible, making sure that it does not interfere with the door opening or closing. With the door closed, attach the magnet to the door directly below the sensing element. The magnet must be within 1 inch of the sensing element in order for it to function properly, so try to keep the magnet as close as possible without interfering with the door opening or closing.


In order to get the best performance out of your Monnit Wireless Sensors, it is important to note proper antenna orientation and sensor positioning. Antennas should all be oriented in the same direction, pointing vertically out of the sensor. If the sensor is mounted flat on its back on a horizontal surface, you should bend the antenna as close to the sensor housing as possible giving you the most amount of antenna pointing vertical. You should make the antenna wire as straight as possible, avoiding any kinks and curving of the wire.
