What are HVAC Sensors?

Having proper heating, ventilation, and air conditioning in the home is important. Many homes today are utilizing powerful technology that will make it much easier for them to have more control over the home’s heating and air, and HVAC sensors are a huge part of that. More and more people want to have smart homes, so learning more about the various options with the latest options for HVAC sensors is a good idea.

History of HVAC Sensors

While the newest technologies are quite impressive and can make controlling the temperature of the home much easier, older forms of HVAC sensors exist. They were simpler devices that would measure the temperature of the air in a room, but they were not always as programmable and flexible as the sensors and units that are available today. Many innovative companies, such as Emerson and Lennox, have worked toward improving the devices and sensors over the years.

What are HVAC Sensors Used for?

The HVAC sensors are going to be able to help you keep your home at the right temperature without needing to do as much work. The sensors are going to be able to measure the temperature of the home, and even the humidity in the home in some cases. They can then relay that information to the smart system that you have in the home to change the temperature by raising or lowering it so that it meets your perfect comfort levels.

What are Digital & Programmable HVAC Thermostats?

Today, you are going to be able to find a number of digital and programmable HVAC thermostats. They are devices that you can install with the heating and air in your home so that you can have a much easier time of controlling the interior climate and increasing your comfort. You can find relatively simple digital thermostats that you will be able to program, as wells as some state of the art interactive touch screens. These make programming even easier. When you are choosing the devices and thermostats for your home, you have to consider a number of different things.

First, you when choosing the thermostat, you are going to have to determine how long the program duration is going to be. Some people have found that the low-end thermostats are not as reliable. Make sure that you will be able to program the device with a program duration that’s long enough for you. Also, make sure that you are able to understand how to program the device easily.

You also want to make sure that the thermostat is going to work in your home, and that means that you need to know the contact rating and voltage. This will ensure that you are getting the right device for your needs and that will work with the electrical system and HVAC system that you have. In addition, you have to consider the switch configuration and how you are going to install the device, as well as what type of supply voltage you need. Keep in mind that even though many of the HVAC sensors and thermostats may seem similar on the outside, that’s not always the case when it comes to how well they are going to function, and the conditions under which they can function.

You also have to think about the temperature in a couple of different ways. First, you will want to know what the maximum and minimum temperatures are going to be for the thermostats. How high can they go? How low can they go? In addition, you want to know what temperatures they are going to be able to function in. Most of the time, you aren’t going to have to worry about it being too hot or cold for your thermostat to work, but it may well depend on where you need the thermostat.

For example, those who are not in a residential home, and who might be working with freezers that stay at or below zero need to have a smart thermometer that will be able to keep the temperature within a couple of degrees. Depending on the location of the thermostat, it could become quite cold, so you want to make sure that it is still going to be able to function properly. The same might be true for those who work in areas that need to be kept exceptionally warm. Even though the modern and rugged thermostats should not have any issues, you should always check to see the max and min temperature ratings for the thermostats you are considering.

What are Heating & Hot Water Programmers?

Just as you want to make sure that you are going to be able to keep the air at the right temperature in your home, you will also want to make sure that you always have the right amount of hot water. It’s never fun to get in the shower to do the dishes only to find that you are out of hot water. When you have a hot water programmer, you will not have to worry about this issue. Again, you are going to have to make sure that you are considering certain things when you are buying the devices to install and to use in your home.

The duration of the program is important so that you can calculate whether it is going to work for your needs. With this programmer, you also want to consider the number of on and off cycles that it has per day, and you want to make sure that it is as easy as possible to program. This will help to ensure that you are going to get the right number of cycles so that you have hot water when you need it, and that you are not wasting energy.

To ensure that it is going to work with the system that you have, you also need to check the switch configuration and the contract rating. Make sure that the supply voltage is going to be sufficient and that it will work with the system.

What are HVAC Humidistats?

One of the common questions that many people ask is “what is a humidistat”? It is a control device that is actually capable of sensing the amount of humidity or moisture, that’s in a room. Not only will it be able to detect the level of humidity, but it is also going to be able to send that information to a humidifier in the home that will then be able to activate or deactivate depending upon the humidity level in the home. While it seems impressive, and it is, it can help to think of this in similar terms to a thermostat, as it really does the same sort of thing.

If you have a humidifying system in your home, you might not need to have one of these devices. In many homes, the humidity can stay just about right without too much interference. When you feel dry, you can increase the humidity and vice versa. However, for those homes that might be near large bodies of water or that might be in a desert, having some help when it comes to keeping the humidity at the right level is appreciated, and the humidistat is going to be able to do a great job of it.

One of the things that you are going to need to consider with the humidistat is location. You want to make sure that the sensor is going to be able to read the humidity of the entire area, to be the most accurate. Mounting them on the wall is common, and can be a good idea. Placing them close to an air return vent can give a good idea of the actual room humidity.

What are Mechanical HVAC Thermostats?

These types of devices are not digital. Instead, they are going to control the temperature and sense the temperature using mechanical means. You will find a number of different options with these types of devices, many of which have been around for a number of years. One of those methods was with a wax pellet. Many believe this was just the way that the temperature was sensed in a vehicle. However, it can also work with hot water controls in the home, particularly the shower. Gas expansion was another option that was quite popular with older thermostats, and you can still find them in gas ovens. Pneumatic thermostats are yet another option.

While these older methods are still in use in some homes and businesses today, and they are still capable of working quite well, they are certainly not the only option. More and more people want to have a home and building that’s easier to control, and that is why the advent of the modern methods of control with digital and programmable HVAC thermostats is growing in popularity.

What are Temperature Sensors?

These are the actual sensors in your HVAC systems that are going to detect the amount of heat in the room. They are then going to relay the information to the programmable thermostat. If you set your thermostat for 70 degrees, and the temperature dips down below that, the heat is going to kick on until the temperature rises. Of course, you can find a number of other types of sensors and uses for them. Labs need to keep things at certain temperatures, as do herpetologists, plant nurseries, and more. You will find a number of different applications for these sensors.

Because they have so many applications, you will find that they have a number of different types of sensing elements. They are going to utilize metallic elements that will be able to determine the temperature. As the temperature increases, the movement of the molecules in the metal can disrupt the way that the electrons flow and that can help to sense the temperature. Some of the common metals include nickel, platinum, and even silicon.

With the sensors that are on the market today, you will find that the actual maximum, and minimum, temperatures sensed can vary based on the device. Most of the time, when the temperatures start to exceed 600 or 700 degrees, temperature sensors are not going to be accurate. Of course, the temperature in a home or business is never going to be that high! Still, you always want to look at the sensors you are buying and check their specifications so you know the minimum and the maximum temperature that they will be able to read with accuracy.
