ALTA Wireless Air Quality PM2.5 Sensors

The ALTA wireless PM2.5 sensor measures PM1, PM2.5 and PM10 concentrations in the air and transmits the measurement to iMonnit. The PM2.5 sensor works by turning on a small fan at the beginning of a measurement cycle to bring in a volume of ambient air and measuring the particulate matter (PM) content of that sample volume. The sensor measures PM content using a laser that scatters based on the number and size of particles suspended in the air. .



Features of the ALTA Air Quality PM2.5 Sensor

• Measures particulate matter concentrations in the air
• Measurement range
  • PM1: 3 to 1.0 um

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 products. Based on inquiries from our customers, our team is currently working on a new carbon dioxide (CO2) gas sensor. The Carbon Dioxide Sensor will use an ultra-low power, high-performance CO2 sensor to measure the amount of carbon dioxide in ambient air, and report the readings back to the iMonnit online software. The CO2 sensor will produce instantaneous CO2 readings and 8 hour time weighted average (TWA) readings with an accuracy of +/- 45 ppm + 3%. The iMonnit software will track the readings and provide notifications when measurements are outside of the user's defined safe level. If you would like to learn more about the development efforts on this upcoming product or be notified when they become available, please email us at sales@monnit.com.

Remotely Monitor and Track HVAC Systems

Are you monitoring your heating and cooling systems for efficient operation and predictive maintenance? Do you know how often your HVAC system is running and if it is running within its correct specifications? Deviations from specified parameters, if left unchecked, can cause expensive repairs and downtime.

Using Monnit Wireless Sensors to test, track and remotely monitor your HVAC systems, allows you to maintain efficient operation and schedule maintenance or other actions to avoid the consequences of failure, before the failure occurs. Monnit wireless sensor systems can help you monitor equipment to help you detect issues before they become serious and costly. We recommend using the following sensors to track and monitor the operation of your HVAC equipment.

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.

Installing Monnit Wireless Sensors for
Remote Property Monitoring

Whether you need to monitor a commercial property or a personal home, remote monitoring solutions can keep an eye on things when you can't. Monnit provides an easy to use remote monitoring solution to track heating and cooling systems for efficiency and preventive maintenance, as well as solutions for monitoring access to a building or restricted area.

We recommend the following products for remote property monitoring:

    Wireless Gateway
    Wireless Temperature Sensors (with Probe)
    Wireless Duct Temperature Sensors
    Industrial Wireless Quad Temperature Sensors
    Industrial Wireless AC Current Meters (150 Amp)
    Wireless Motion Detection Sensors
    Wireless Open/Closed Sensors

AC / Furnace System Installation

Before starting any part of this installation process, shut the power off to both the condenser unit and the inside air handler unit. For the indoor portion of the HVAC monitoring system, start by installing a Monnit wireless gateway. The gateway can be located anywhere in the building where it has access to power and a decent cellular signal (for Cellular gateways), or access to an internet router (for Ethernet gateways), or a PC (for USB gateways). For indoor sensors, we recommend using a wireless duct temperature sensor to monitor the output ventilation air that is being sent from the air handling unit back to the building and a wireless temperature sensor that can be installed near the thermostat or air return, to track ambient room temperature.



For the outside condenser unit, we recommend using a Monnit industrial wireless quad temperature sensor as it comes in a weatherproof enclosure suitable for outdoor use. The quad temperature sensor has four independent temperature probes that can monitor and collect temperature readings for the key areas of the condenser unit. Each temperature probe is labeled 1 through 4.

Start by connecting one of the temperature probes to the suction line, one to the liquid line and another one to the discharge line making note of which probe you are connecting to each. When connecting a temperature probe to any of these refrigerant lines, we recommend using a zip tie to fasten the probe securely against the bare metal tube. After securing the temperature probe, use thermal tape to wrap the probe entirely to the refrigerant line. This provides a thermal barrier allowing the sensor to get a more accurate reading of the refrigerant line temperature. For the remaining probe, we recommend fastening one to the fan grate to capture the discharge air temperature. Alternately you can use any of the probes to capture outdoor ambient temperature if you prefer.

We also suggest using a Monnit industrial wireless AC current meter (150 Amp) to track the current draw of the compressor. The AC current meter uses a clip-on current transformer that should be clipped around the "hot" power wire feeding the compressor.

Monitoring Indoor Temperatures

We recommend using Monnit wireless temperature sensors near any heating system thermostats, then adding additional sensors for areas of the building that are prone to temperature issues.



Monitoring Access to the Building

Monnit wireless open/closed sensors and wireless motion detection sensors can be used to monitor access to a building or room. Open/closed sensors are mounted next to the door or window with the magnet mounted to the door or window adjacent to the sensor with 1 inch or less gap. When the door or window is opened, the sensor detects the magnet moving away and sends an immediate alert. Motion detection sensors use passive infrared technology to detect human movement. They can be mounted to any surface and have a viewing angle of 50° each direction from center and detect movement within 16 feet of the sensor.
