What are the best sensor kits for arduino that we can buy at a good price? List 2021

If you are already familiar with the Arduino and how it works, you may want to expand your horizons a bit more and try new projects. For beginners, it is advisable to start with the Arduino UNO board (official or generic) or with a starter kit, which brings the basic components to know the board, the programming environment, etc.

However, once you know everything about this world, you may want to go a little further . Therefore, it is an excellent idea to have sensor kits to incorporate into projects.

There is a wide variety of them on the market, but not all of them are of good quality or accessible to the user. Consequently, we will show you which are the best sensor kits for Arduino that you can buy at great prices.

What should we keep in mind when buying an Arduino sensor kit to learn?

The first step to consider when you want to start in this world is what type of plate you should buy . This will depend on the needs you have and the budget. Once you have chosen the one that best suits what you are looking for, it can be a great idea to get yourself a sensor kit.

The beneficial thing about this is that thanks to the kit, you have in your hands great possibilities to execute all kinds of projects . It should be noted that the use of them is aimed mainly for beginners, so that they can become familiar with the tools and materials, and start experimenting until they know everything they can do with a simple Arduino board .

If you want to start with your first projects, you must analyze how much money you have for it. With basic kits of few pieces it will be enough, however, if you really want to enjoy and know much more, we recommend you purchase the official Arduino Starter kit with Arduino UNO .

Despite its price of around 70 euros, you will have in your hands not only elements such as cables, breadboard, servomotor, motor, LEDs, push buttons, LCD screen, sensors, etc., but also a complete manual in Spanish with 15 basic projects .

Best Arduino projects with sensors that you can assemble yourself at a low cost

If you want to start testing the sensors, here are some ideas about the best Arduino projects with sensors that you can build yourself from home and at a low cost.

Take note:

Connected scale

To carry out this project, you will need the help of a 3D printer to make the case and some of the parts. Apart from that, you will use an Arduino board and a series of sensors that will serve to detect up to 200 kg of weight .

In this way, you can design your own connected scale that has access to the IFTTT service, in order to be able to connect with other quantification accounts. It should be noted that this work is not as complicated as it seems and, with a few simple steps, you will already have this interesting modern scale at your disposal .

Automated garden

Another amazing project that you can accomplish with the help of Arduino sensors is an automated garden . The advantage of this is that through the use of temperature, light and humidity sensors, it is possible to configure the automatic watering of the plants in your garden. If you have indoor plants, you can also control both the temperature, humidity and amount of light automatically that your plants will receive throughout the day. This results in a wonderful autonomous garden.

Radar to detect objects

This is a very unusual idea, but certainly an interesting one. It is responsible for drawing on a map (created on a PC thanks to Processing) the presence of certain objects by means of an ultrasound sensor . This element has a range of up to 4 meters, with a 180 degree coverage / turn. Radar to detect objects can be a great idea to do search activities with your children, or even to help you find missing items.


Tasks that were originally analog can begin to be automated and performed more advanced thanks to Arduino and different sensor kits. This is the case with this particular mousetrap .

It is not as simple as it seems and it takes longer than expected, but the result will leave you fascinated if you want to capture the mice in your home without hurting them. The project consists of a cage suspended by magnets, which by means of proximity sensors are able to recognize when there is a mouse inside and make the trap fall. Finally, we recommend that you include light and sound indicators, which will serve as alarms when the system has worked.

Automatic opening bin

This last idea is probably the simplest of all but very practical for day to day. It is a trash can that opens automatically when your hand approaches it . To do it, just use an Arduino board and a simple ultrasonic sensor. Thanks to this mechanism, you will forget to manually open the bins in your home, office or other spaces. Just by bringing your hand closer, the lid will open and you can deposit the garbage without problems.
