Is A Smart Thermostat Capable Of Detecting Room Occupancy?

If you know anything about smart thermostats, your next question is probably – can it detect occupant presence? That’s a fair question, and it’s one of the many features that Smart Thermostat has built-in devices. However, we need to dive into some technical details to answer. So let us share a few details regarding that.

But before we can answer if a smart thermostat can detect room occupancy, let us tell you what room occupancy is in a smart thermostat?

 

It’s the percentage of time occupied by a heating or cooling system. The motion sensor is what smart thermostats use to determine room temperature and is also required to implement scheduling functionality. That is precisely what most people need. In fact, as per a study by Berkley Lawrence National Lab, about 90% of U.S. citizens admit that they’ve rarely programmed a thermostat because they don’t know how to do it. This is where smart thermostats come into the frame.

It detects when someone enters or leaves a room and appropriately adjusts the temperature. When no one is present in a room for a set period, the thermostat will change to “away” mode, turning the heat or air conditioning down to its minimum level. This means that you don’t waste energy heating or cooling an empty house. Additionally, saving energy.

 

How does an occupancy sensor work in a smart thermostat?

An occupancy sensor is a motion detector that can turn the heating and cooling system on and off without you ever lifting a switch. Using ultrasonic technology, a light management module processes and tracks the reflected sound waves to determine if the room is occupied or not. If the sensors sense occupancy, they will power up or remain switched on. This reduction in power consumption helps to lower energy costs.

For instance, when a movement is detected in the room – a controller can determine that motion has occurred and triggered an event, such as turning on the AC. 

 

Does a smart thermostat necessarily have to detect room occupancy?

A smart thermostat collects information from many sensors around your home to increase comfort and energy savings. But one of the essential sensors to detect room occupancy is a motion sensor.

Thanks to these motion sensors, you no longer have to adjust your thermostat to conserve energy because the motion sensor built in the thermostat does it for you. Also, it allows the system to detect room occupancy. It automatically turns off the heat or air conditioning whenever there’s nobody there and turns it back on when somebody goes into that room again.

The sensor is particularly useful if you have a large home or if people are moving in and out of rooms throughout the day. The motion sensor can help your thermostat adjust the temperature appropriately so everyone can be comfortable.

 

Do you really need a smart thermostat that detects room occupancy?

Suppose you have a smart thermostat, and it doesn’t have any motion-sensing technology. In that case, you are missing an opportunity, especially if you’re trying to save money on your energy bills.

As we know, a considerable portion of the energy used by our homes is wasted because we overcompensate for energy use during the day when no one is home and the rooms are empty. We don’t need to heat or cool these rooms at full capacity. And so, the Room Occupancy Sensing System present in the thermostat detects room occupancy and modifies your existing smart thermostat’s settings accordingly, providing you with maximum cost savings while keeping your environment comfortable.

 

So, what’s the bottom line here?

You’re still left to decide if their claims are truthful at the end of the day. But we would recommend that if you’re looking for a way to reduce your energy usage and lower costs and you don’t mind spending the extra bucks for convenience, a Smart Thermostat with an Occupancy sensor may be right for you.
