Skip to the content Atmospheric sensors include temperature, humidity, atmospheric pressure sensors, and barometric pressure, Particulate Matter (PM) and Air Quality (AQI). Temperature, humidity and barometric pressure have been used for research and weather forecasting for centuries. PM and AQI are becoming more common with concerns about air quality and health. Comptus sensors are designed for connectivity to data loggers, monitors and system controls.
Atmospheric sensors that detect temperature are thermistor devices. Based on the current conditions, the sensor’s electrical resistance changes. A reference voltage applied to the sensor views the voltage signal received, which is how it comes up with an accurate calculation.
Surface temperature transmitters are designed for applications requiring direct contact surface temperature monitoring. The device includes a high temperature adhesive to ensure contact with the surface. The paste type sensor is well suited to commercial and industrial applications where a correlation between temperature and performance are measured, such as photovoltaic (PV) panels.
Another atmospheric pressure sensor measures the level of air pressure in the atmosphere. The internal aneroid cell measures the degree of weight produced by air molecules. Most often, meteorologists use these atmospheric sensors to forecast the weather. Facility operators will monitor barometric pressure for a number of reasons including pressure balancing large structures. These sensors often work alongside atmospheric pressure transducers to provide accurate data.
Leonardo Da Vinci is credited with inventing the hygrometer, or humidity sensor. Modern devices detect changes that alter electrical currents or temperature in the air. There are three basic types of humidity sensors: capacitive, resistive and thermal. All three types will monitor minute changes in the atmosphere in order to calculate the humidity in the air.
The A70H-HTP humidity, temperature and pressure sensor is an example of what we offer. They’re ideal for input to control systems or used in combination with electronic data collection systems. Additionally, devices like an ambient pressure sensor help monitor and balance environmental conditions.

Atmospheric sensors are used to measure and monitor key environmental parameters such as pressure, temperature, humidity, and wind. They play a vital role in meteorological stations, environmental research, HVAC systems, aviation, and industrial automation.
Both terms often refer to the same technology. A barometric sensor specifically measures air pressure, while atmospheric sensors can include additional environmental sensors like temperature, humidity, or wind components. Together, they provide a full picture of atmospheric conditions.
Atmospheric pressure sensors help predict weather changes, monitor environmental stability, and control automated systems. A drop in atmospheric pressure can signal storms or low-pressure systems, making these sensors critical for forecasting, aviation safety, and industrial process optimization.
Atmospheric sensors are used in weather stations, environmental research, industrial and HVAC systems, drones and aerospace, and smart agriculture for monitoring and control applications.
High-quality atmospheric pressure sensors, like those made by Comptus, can achieve accuracy levels of ±0.25% or better. Accuracy depends on sensor design, calibration, and environmental factors such as temperature and humidity.
Temperature and humidity can slightly influence air pressure measurements. Advanced atmospheric pressure sensors include built-in temperature compensation to maintain consistent accuracy, even in rapidly changing conditions.
Yes, periodic calibration ensures long-term accuracy. Most atmospheric sensors require minimal maintenance just to keep the sensor clean, dry, and protected from direct water exposure. Calibration intervals vary depending on environmental conditions and usage.
Comptus atmospheric sensors are built for durability, precision, and long-term reliability. Each sensor is made with high-quality materials, rigorously tested, and designed for easy integration with data loggers and control systems used in meteorology, industry, and research.
Yes! Atmospheric pressure sensors can calculate approximate altitude because air pressure decreases as elevation increases. This makes them ideal for aviation, drone navigation, and environmental fieldwork.
