With HALO HVAC IoT Wireless Control you can monitor and control your HVAC system in real-time through wireless sensors and remote monitoring. Improve energy efficiency & IAQ.

HVAC Remote Control
- Principles of operation

The HALO HVAC IoT control unit features two relays controllable through the Halo web portal or network-triggered notifications. Four LEDs indicate power status, online communication, and relay status. Manual relay control and changes can be temporary or indefinite.


The relays can also be automatically controlled by wireless sensors, with user-defined messages triggering relay switches. For instance, a water sensor detecting a certain water level activates the relay to turn on a pump, which switches off when water is no longer detected.

Service & Maintenance
- Redefined 

HALO HVAC's advanced IoT technology redefines both planned preventative and reactive HVAC service and maintenance. Our state-of-the-art system delivers centralized visibility for all property assets through an intuitive platform accessible via smartphone or laptop. This cutting-edge solution automates data collection, providing real-time insights that offer a comprehensive view of HVAC asset operational status.


This ground-breaking technology empowers users to assess processes and proactively deploy qualified engineers equipped with the right tools and parts, ensuring continuous operation and cost-effectiveness. With Remote HVAC Asset Monitoring, users can effortlessly access a data-driven overview of operational efficiency and monitor customized parameters from any location.

HALO HVAC IoT Sensors for remote HVAC monitoring;

Duct temperature  

Perfect for remote duct temperature monitoring, you can use the HALO HVAC IoT sensors for Duct Temperature for temporary testing or full-time system monitoring. 


Indoor environmental conditions are constantly shifting, but HALO HVAC Wireless IoT sensors for Temperature can track all of the changes. This makes it possible to chart your HVAC system's fluctuating atmosphere throughout your facilities. 

Power Usage 

Fluctuating power consumption often indicates that: a component needs maintenance, is nearing the end of its service life, or an unexpected supply issue. HALO HVAC IoT sensors are ideal for submetering. 20- 500Amps

Air Velocity

It’s important to measure airflow or velocity in an HVAC system to optimize performance, increase energy efficiency and cost savings, and maintain proper airflow rates to ensure occupant comfort. Ideal for before and after AHU refurbishments & EC Fan upgrades.

Differential Air Pressure

A HVAC system's primary purpose is, of course, to push air through a building. HALO HVAC Wireless IoT sensors for Differential Air Pressure helps ensure that it does. 

Air Quality

The air we breathe matters. To ensure the air circulating through your vents and in your buildings is clean and free of pollutants in the form of various particulate matter (PM), you need the HALO HVAC IoT sensor for Air Quality.


HALO HVAC IoT sensors for Humidity remotely monitor RH with a +/- 3% accuracy (between 10–90% RH), temperature, and dew point in facilities or enclosures. If the humidity exceeds your specified limits, these scientific-grade IoT sensors instantly alert you via text, email or call.


HALO HVAC IoT sensors for motion and vibration capture data from machines, processes, and critical infrastructure. When excessive vibration, jarring harmonics, or abnormal motion detected, an alert is issued via text, email, or call.

Open / Close & Access Doors

HALO HVAC Wireless IoT sensors help you remotely monitor door, window, cabinet, or lid status. Get an alert via text, email, or call if something’s been left ajar or accessed when it shouldn’t.
