Your HVAC system is only as smart as the sensors guiding it. A slight fluctuation in temperature or pressure can mean wasted energy, rising costs, or an uncomfortable space. Control Traders supplies high-quality HVAC sensors and transducers designed for precision, efficiency, and control. Whether it’s indoor air quality, temperature, or pressure, our sensors do the monitoring. Explore our range of sensors and find the right accessories for your HVAC units.
HVAC sensors act as the system’s eyes and ears, detecting changes in temperature, humidity, and air pressure. They send signals to the control system, which then adjusts heating, cooling, and airflow to maintain comfort and efficiency. Without these sensors, systems would run blindly, wasting energy and money.
Even a slight temperature shift can mess with indoor comfort and efficiency. Control Traders’ range of room, duct, immersion, and outdoor sensors help your HVAC system stay on point. A well-placed sensor means no more hot or cold spots but steady, reliable climate control.
Humidity can make or break indoor comfort. Too much moisture and you risk having mould and sticky air. Too little? Dry, scratchy throats and static shocks. Indoor and outdoor relative humidity sensors help HVAC systems adjust on the fly, keeping conditions just right.
Good airflow is everything. Blockages, leaks, and pressure imbalances waste energy and overwork your system. Pressure sensors and transducers detect shifts in ducts, refrigerants, and water systems before they become costly problems. Smart pressure control means better performance, lower energy bills, and a longer-lasting HVAC system.
CO₂ buildup leads to stuffy, stale air. Carbon monoxide leaks are silent but more deadly. Our carbon dioxide sensors improve ventilation by detecting when fresh air is needed. CO sensors protect against dangerous leaks. For safer, cleaner air, these sensors are a must for any HVAC setup.

HVAC systems use temperature, humidity, pressure, CO₂, and occupancy sensors to keep indoor air quality, airflow, and comfort in check. Without them, your system is running blindly and on open loop control, not actually controlling.
The big four in HVAC are temperature sensors (for heating and cooling), indoor humidity sensors (to prevent dry air or mould), pressure sensors (to maintain airflow), and air quality sensors (to monitor CO₂ and pollutants). Control Traders stocks all types of sensors. Use the search bar above to check whatever type you need for your HVAC.
HVAC systems rely on thermocouples, RTDs (Resistance Temperature Detectors), thermistors, and semiconductor sensors. Some react fast, some last longer, but all help control air temperature accurately.
The location depends on the job. Duct sensors track airflow in the air duct while room sensors monitor indoor climate. On the other hand, pipe sensors monitor water temperature in hydronic heating, chilled water, and refrigeration systems. Finally, outdoor sensors are found in rooftops and building facades, adjusting the system to changing weather.
Too much CO₂ can lead to stuffy rooms, tired people, poor air quality and can be fatal. CO₂ sensors tell your system when to bring in fresh air, improving comfort, health, and energy efficiency.
