Sensors enable us to receive signals from the outside world. Technically, sensors are objects capable of receiving a signal, and when this signal reaches the predefined level of sensitivity of the sensor, they are able to send information to the rest of the circuit. Sensors are often used in robotics, as they enable robots to communicate with their environment, be it by vision (light and colour sensor), hearing (sound sensor) or smell (gas sensor). We offer a wide variety of sensors for all applications and price ranges.



  • Accelerometers

    Accelerometers are popular sensors used to measure linear acceleration. So when you move your mobile phone you can control apps or even games just by accelerometers. We offer Arduino compatible accelerometers from manufacturers such as SparkFun as well as cheaper options. Check their parameters to make sure they fit your project. Also, if you have any questions, check out our technical support, learning page or forum.

  • Air quality sensors

    Air quality sensors can inform you about air pollution by selected particles or gases, be it dust or CO2. The most important parameters of sensors are their sensitivity and power supply voltage. Check out our offer and training materials to learn more. 

  • Temperature sensors

    Temperature sensors will let you measure the temperature around your project and possibly program the reactions you want your project to make in response to temperature differences. With these sensors you can also build a basic thermometer. The important things to consider when selecting a temperature sensor are the temperature range in which it works, measurement accuracy and as always the supply voltage. In our offer we have sensors from -55°C to 125°C.

  • Magnetometer Compas

    Magnetometers make it possible to detect the direction of the earth's magnetic field, so they work like a compass. We can integrate them with your project in order to orientate it to its current geographical location. We offer a wide range of sensors in all price ranges. See our website to learn more

  • MEMS Sensors - Gyroscope

    Sensing devices including gyroscopes are often used to determine the orientation of an object. Accelerometers, gyroscopes and magnetometers all serve this purpose. Despite a similar field of application, they each measure different quantities. Traditional gyroscopes included a part that rotated like a spinning top. Electronic gyroscopes clearly no longer have mechanical elements but imitate angular velocity detection and measurement. In our offer you will find a wide selection of gyroscopes in different cost and quality levels.

  • Inertial Sensors - IMU

    Inertial sensor is essentially a combination of accelerometer, gyroscope and magnetometer. By combining the three sensors it is possible to track the movement of the object in full or in space depending on the measuring axes.

  • Medical sensors

    Not only medical devices have advanced substantially over the last few years, but they have also become much more affordable for the individual user. Both muscle tension and pulse sensors can be found in our offer.

  • Magnetic sensors

    Magnetic sensors react to the change of the magnetic field. Thus the sensor can initiate predefined actions in your project by the presence of magnetic objects in its environment.

  • Flow sensors

    Flow sensors measure water flow pressure levels transmitted by the sensor device. Check out our offer if this is an item you need!

  • Fluid level sensors

    Liquid level sensors normally have a float that measures the level of the fluid in which it is immersed. The liquid level sensor acts as a switch. The state is changed by means of a magnet located on the float. It can be used to detect liquid levels that are too high or too low.

  • Weather sensors

    Barometer, temperature sensor, humidity sensor, water level sensor... if you put them all together you can easily create a simple weather station. We offer you all those modules under one category and sometimes on one board thanks to sensors like the BME280, BMP280 or BMP180. All at very competitive prices - check out our offer of weather sensors and find everything you might need for your unique project. 

  • Current sensors

    Current sensors include primarily Hall effect sensors enabling detection of current flow through the magnetic emission caused by Hall effect. Solectroshop offers broad offering of sensors in this category from the module SH3144E itself through the integrated circuit for Arduino applications up to non-invasive sensors such as SCT013030. 

  • Distance sensors

    Distance sensors are an essential element of most of the robotic projects - be that Arduino projects or any other. In essence there are two key types of distance sensors - infrared and ultrasounds sensors. In our offering you will find both of them with a wide range of products based on the bestsellers such as TCRT5000 and HC-SR04. We offer as well assembly elements including plastic mounts.

  • Proximity sensors

    Inductive proximity sensors work with metal objects thanks to magnetic field interaction. In contrast to the optical sensors, proximity inductive sensors can actually sense an object through another object (if an obstacle is made out of other material than metal). Revise our wide offering of inductive proximity sensors

  • Light and colour sensors

    In this category, you can find a wide array of color and light sensors ranging from the  most basic LDR fotoresistors up to the modules preset for Arduino applications. Check out our offering and benefit from the best prices and detailed product explanations

  • Sound sensors

    Sound sensor is a module converting acoustic waves into electrical signal. In very simple terms, sound detectors work based on capacitance changes caused by sound wave vibration. Air vibration moves the diaphragm in the microphone causing capacitance change in the coupled capacitator. Capacitance change than gets amplified by module (LM386, LM393 or MAX9812L to name some currently in our offering) resulting in signal read. Check out all our microphone modules!

  • Pressure sensors

    Pressure sensors or force sensors are modules converting force applied to a given element to an electric signal. There are plenty of types of force sensors with the most popular being load cells. When choosing a right load cell you should pay special attention to maximum load and the core module of the sensor. In our offer we have a range of load cells with loads from 1kg up to 20kg.

  • Gas Sensors

    Gas sensors - Solectroshop offers wide range of gas sensors based on the most reliable MQ modules. Our modules fit all purposes from detection of fumes or smoke up to air quality checks. Review our offering in gas sensors!

  • Reflection sensors

    In robotics reflection sensors most frequently are used in line follower applications, i.e. when we want to make the robot follow a line as in many robotic competitions. In Solectroshop we offer a broad range of optic sensors with a subset of reflection sensors represented by modules such as FZ0888 or CNY70. 

  • Motion Sensors

    Motion sensors or motion detectors are devices that are used for automation. This solution helps us to build lighting systems that react to our presence in a room. However it has even more advanced applications in robotics, as it can cause different reactions from the robot of our project. Our motion sensors are of the highest quality and are easy to use. If you have any questions, please consult our forum or technical support.

  • Moisture sensors

    Every indoor living space, whether industrial or residential, must not forget about the humidity levels that are present. It is essential for health and good vibes of people who are present inside. The humidity sensor, which will inform us about the humidity in the room, is therefore a very useful device. It will ensure optimal conditions for living or working indoors. In our shop we have a wide selection of humidity sensors and devices equipped with probe sets, all at affordable and attractive prices. We invite you to shop in our Solectroshop online shop! Here you will find a humidity sensor and much more!

  • Fingerprint Readers

    "Fingerprint Reader" - How can we increase the security of protecting our valuable property? One method is to use biometric devices, such as a fingerprint reader, which until recently was only found in forensic medicine to help identify suspected criminals, and which is now also used to secure property. How does the fingerprint reader work?  In the fingerprint scanner, a system of properly arranged LEDs sends light to a glass, plastic or transparent surface, on which a finger is pressed. The quality of the fingerprint can vary with each application, depending on the degree of contamination of the finger, the test surface of the fingerprint or the colour and intensity of the light in the immediate vicinity of the reader. The light emitted by the LEDs is reflected on the surface of the fingerprint scanner and is received by an image sensor based on CCD or CMOS technology.
