Smart Sensors: How Much Do They Cost And How Can I Save Cost?

How Much Do Smart Sensors Cost And How To Save Cost?

If smart lights, thermostats, and security cameras are the staples of the smart home, think of smart sensors as the invisible network meshing everything together. Or, if you prefer, the eyes of the smart home.

Obviously, there are many sensors out there designed to fulfill different purposes: movement sensors, light sensors, temperature sensors, and plenty more.

Hence, this article focuses on the popular smart sensors, the cost of acquiring them and how to save costs altogether.

Below, we’ve broken things down into the major categories of smart home sensors and included some of our top picks.

Smart Sensors: How Much Do They Cost And How Can I Save Cost?

Motion Sensors

We already know what these can do, as these are the most common type of sensor, and one we’ve been familiar with for decades to this point. In the past, they opened doors at the grocery store, turned on hand dryers, and more. Today, they accomplish much more.

As the name implies, it detects movement in a select area of your home and can send you an alert, trigger a siren or turn other connected devices, such as lights, on or off based on motion or lack of it, just like we find in the movies.

Most motion sensors I have come across have an adjustable sensitivity that lets your technology ecosystem know when and where you are in your so that it can tailor function around the way you live.

But nonetheless, always put the motion sensors in places people are likely to pass by, as this will make it more accurate and increase its capacity at detecting movement. 

On average, smart sensors cost $32 to purchase. Some of the many ways they help to save cost include:

  • Enhanced energy efficiency
  • Home/business security
  • Gadget regulation/maintenance

We’ll look at these in better detail in the course of this article

There’s something known as PIR when researching about motion sensors, it stands for passive infrared sensor, which enables motion sensors to detect warm bodies as they pass by.  Some other kinds of motion sensors are available but PIR is arguably the most accurate, and oftentimes you find that some motion sensor has a combination of more than one type.

Here are our top picks for Motion sensors:

Hue Motion Sensor


Philips Hue Zigbee’s motion sensor is focused less on security and more about using its motion sensor to turn on the lights in your home.

This would be a great fit for you if you are concerned less about security and more on beautifully decorating your smart home.

Samsung SmartThings Motion Sensor


Samsung’s Motion Sensor is literally a handy device to put anywhere in your home, it can fit into a small or large space by sticking it to a wall or furniture and then using its magnetic mount to get the coverage you want.

It helps to detect motion and temperature, and trigger lights, alarms or perform any smart home routines based on any of these.

Temperature and Humidity Sensors

Smart thermostat always goes hand in hand with temperature sensors, they do not just complement each other but also ensures they perform their best. 

In other words, temperature sensors are most effective in making your smart thermostat more efficient.

For example, every smart thermostat should have a temperature sensor for they can be super helpful when they’re alerting you that it’s too hot or humid and Temperature sensors are great for effectively cooling or heating rooms.

No doubt, you’ve heard of the Ecobee room sensor, it is one of the best smart thermostats in the market places. It has really good features but the coolest thing of note is  Ecobee’s Room Sensors also check for occupancy. So if they sense that someone is in a room, it’ll heat it up, but if not, then it won’t waste the energy. This can save you a great deal of cost and energy.

Without further ado, here are our top picks for Temperature and humidity sensors:

Ecobee Room Sensor


To use this, you’ll need an Ecobee Smart Thermostat, Ecobee4 or Ecobee3 Lite, and the result achieved is a much more intelligent way to heat your home. 

The sensors measure the temperature of individual rooms as well as where people are – so it can heat the home more efficiently.

Monoprice Z-Wave Sensor


This does it all: temperature, humidity, motion, and light. It, therefore, a perfect fit for you.

Moisture/Water Leak Sensors

Returning home to a drenched house can be frustrating and frankly, very surprising if you know what I mean and you have probably been looking for a way to detect that leak all to no avail.

I recommend you purchase a water leak sensor as these sensors come handy preventing leaks from occurring or at least giving you a heads up.

A lot of the traditional moisture leak sensors make use alarms to alert you that something’s sprung a leak, but there’s a huge possibility that you’re not home to hear it blaring.

A major consideration on your part should be whether you want audible alerts as well as smartphone notifications as most of these sensors do both but not all. Also, it could be in the form of a text or a call, whichever one you prefer. Some sensors require a hub to serve as an intermediary while some can connect directly to Wi-Fi. If you want to connect your water sensors with other smart home devices – say, to switch off your lights if a leak is detected – then some will let you do so.

It’s important to note that Moisture detectors can be placed in many places, but putting it in obvious risk areas is what matters most; it could be on washing machines, heaters, bathtubs, and sinks, there are many more but these are great examples that readily to mind.

 Here are our top picks for Moisture/water leak sensors:

iHome Wi-Fi Dual Leak Sensor


The iHome leak sensor doesn’t go quietly into the night, what do I mean by this?

When triggered, It is loud as hell. It also has the option to push alerts to your smartphone – or integrate it with other iHome devices if you have them.

It has dual probes for added and a battery life of two years.

Samsung SmartThings Water Leak Sensor


Samsung’s leak sensor doesn’t have as much coverage as the iHome, but it’s still easily one of the best options out there. It also monitors the temperature, and you can tie it up with Alexa or Google Assistant with its SmartThings integration. Totally cool.

Door/Window Contact Sensors

Did you know that contact sensors are most often used as part of security systems?

It is mostly put on doors and windows to tell if they’ve been opened. This also applies to – blinds, fridges, drawers, garage doors, doggie doors, medicine cabinets, you name it.

All you need to know  If it opens and closes you can stick a contact sensor on it.

Most users tend to use them as standalone devices, but you can pair them with a smart home system like SmartThings, Apple HomeKit or Amazon Alexa to do useful stuff such as having the lights turned on, disabling your alarm systems, and perhaps you could program that the TV turns on or the kettle starts boiling when you open the front door.

Here are the top pics for contact sensors:

Samsung SmartThings Multipurpose Sensor


Samsung’s Multipurpose Sensor is a three-in-one gadget that monitors contact, temperature, and vibration. It’s really useful on doors – especially a front door as it can detect knocking. Basically, you can stick it anywhere two things connect such as cabinets or windows. Also, the whole device is magnetic and you can easily attach it to a metal gate, mailbox or door. It works with Samsung’s SmartThings hub and Amazon Alexa’s Echo Plus or Show 2.

Stitch by Monoprice Wireless Smart Door/Window Sensor.


This is a Wi-Fi contact sensor, Stitch is compatible with Alexa and Google Assistant, as well as its own app. No hub is required, however, so you could just stick this on your front door and know when anyone opens it.

It’s one of the few Wi-Fi sensors with Alexa Routines too, even without one of Amazon’s Zigbee hubs, which is a great feature that lets you connect it to your other smart home stuff. Stitch also has a motion sensor, although it didn’t make our list you could also give it a try.

How Smart Sensors Saves Cost

This use of smart sensors is carried out extensively by governmental departments, as they reduce energy costs especially in terms of lighting. This is a very important factor in smart homes as all the appliances in it need energy to power and operate.

As you already know, smart sensors are pre-equipped on a number of gadgets and electrical devices–refrigerators, televisions, and more–so that they can detect smoke and temperature emanating from or surrounding those respective devices. These sensors can thus alter the functionality of built-in fans or shut down the device itself to avoid any potential mishap, thus saving lives, as well as costs.

Home security is just one area where smart sensors are helping people and businesses reduce costs and increase overall safety. Almost every business is using these effective sensors to improve their services and to enhance security over various departments. These sensors have definitely transformed various aspects of life, and they will continue to do so with the ever-advancing accomplishments of technology.

The point remains that reduced energy consumption and enhanced energy efficiencies lead to money savings, and that is what these smart sensors will accomplish for you because that is the essence of their design.

The Bottom Line

It’s obvious that smart home sensors can add to the safety and security you need in your home.

Irrespective of the smart devices you’ve chosen for your own home, you’re going to incorporate sensors of some type. It’s best to get educated about smart sensors, their costs and how to save costs before and after making a purchase. We hope you find this article informative and inspiring.
