Using advanced intelligent room sensors, occupants could be encouraged to reduce the comfort thermostat temperature when a building is unoccupied to save energy costs.
ACEEE reports that the average office can save up to 18% on annual HVAC energy use by installing occupancy-based wireless thermostats.
Temperature sensors are electronic devices that measure and convert temperature into an electrical signal. They are commonly found in our homes and a variety of industries.
A common type of temperature sensor is the thermistor, which measures the change in resistance of an electric circuit. It can be used for various applications, from domestic water heaters to microwaves and refrigerators.
Another type of temperature sensor is the resistive temperature detector, also known as an RTD. Like a thermistor, an RTD changes the electrical resistance of a coil to detect temperature changes.
There are many different temperature or room sensors like at Neat, and it’s essential to know the one that suits your needs. A great place to start is with our industry-leading experts, who can provide all the information and help you choose the best device for your application.
The humidity sensor is essential in many applications, such as HVAC (Heating, Ventilation, Air Conditioning) and comfort optimization. It is also a vital tool for food manufacturing, agriculture, biomedical industries, and more.
Humidity sensors are electronic devices that measure and report the moisture and air temperature of the surrounding environment. They also say relative humidity indicates the amount of water vapor compared to the maximum amount in the air.
There are several types of humidity sensors, which can be classified according to the method that they use to measure humidity. They include capacitive, resistive, and thermal.
A light sensor can be one of the most powerful devices in the smart home, as it measures the luminosity (light intensity) of a particular space. It can be an essential component of intelligent rooms that optimize energy efficiency.
A common type of light sensor is a photoresistor, or LDR for short, which changes its resistance in response to the amount of light it receives. This type of light sensor is most commonly used in low-cost systems and has a relatively long response time (milliseconds) for measuring the amount of change in light intensity.
A second type of light sensor is a phototransistor, or PTR for short, which converts light energy into electricity, like a solar cell. A third type of light sensor is a photodiode, or PDD for short, which can be used to read the electrical signal produced by a phototransistor.
Motion or passive infrared (PIR) or radio wave sensors detect motion and heat within a covered area. They use a small sensor that emits infrared light, which is then reflected the sensor by moving objects.
The type of motion detector that you choose depends on your home situation. Some sensors work best in homes where movement is frequent. Others may be better suited for homes with multiple levels or near airports.
Another common type of motion detector uses microwaves to read the surrounding space. The microwaves bounce off objects and return to the sensor, which measures their reflection rate.
These types of motion detectors are relatively impervious to false alarms. They can be used in areas with limited visibility or in rooms where kids and pets frequently play. They can also be paired with other sensor technologies to activate lights only when both types of technology detect movement in the same space.
