The Arduino platform has been considered for years as probably the best solution in the field of programmable electronics. The main advantages are: ease of programming, a wide range of fully compatible overlays (Arduino Shields) and the availability of different versions of main boards (the official ones and hardware compatible substitutes). All these means that Arduino platforms, together with the Arduino IDE programming environment, have become an integral part of robotics. Both amateurs and professionals reach for tiles. The tiles have entertainment and research applications, and are also used to develop businesses (including projects related to the Internet of Things and production lines). In this category we have placed various sensors for Arduino, which offer is so wide that we had to divide the list into several more subcategories. From a technical point of view, sensors are devices that provide information about the appearance of a particular stimulus or exceeding a given value. We invite you to familiarize yourself with various sensors, including sensor sets for Arduino, the Grove series, the Gravity series and other products.

Sensor kits for Arduino
Contrary to appearances, it is not difficult to ensure the compatibility of external components with Arduino - you just need to ensure that the voltage levels (up to 5 V DC or 3.3 V for some controller versions) and the current consumed (preferably not exceeding a few or several milliamps) are compatible. If a given element requires a small number of wires, most often just a few male-female or female-female cables are enough to enjoy a working system. But what to do if you are just starting your adventure and would like to learn as much as possible in the field of programming and electronics? Be sure to check out the Arduino sensor kits available in our offer. Each of them contains a set of sensors and many other basic elements that will allow you to become familiar with various aspects of electronics - support for analog and digital inputs, digital outputs, local serial communication standards (I2C, UART, SPI), or PWM modulation. A very frequently purchased sensor is the Arduino proximity sensor, which is used in many projects.
DFRobot Gravity series
The designers from DFRobot know perfectly well how complex and difficult electronics is, especially in connection with programming microcontrollers, at the beginning of the adventure with this beautiful field. That's why they created the DFRobot Gravity product line. Each module is connected to Arduino using a three-wire cable, providing power to the board (black and red wires) and transmitting a signal to the microcontroller input (in the case of sensors) or from its output (in the case of executive modules, e.g. buzzer or relay). Importantly, the colors of the wires and goldpins on the dedicated overlay allow for easy identification of the functions of a given module. DFRobot Gravity allows you to quickly learn how to use various types of sensors by implementing many interesting projects according to ready-made examples or your own imagination.

Sensors for Arduino - FAQ
The main task of motion sensors is to precisely and immediately detect movement in the room, specifically within the sensor's operating range. When motion is detected, the sensor can activate, for example, a sound or light alarm. The distance sensor, depending on the specific model, may have a range ranging from 2 m to even 11 m. The operating range of other Arduino -compatible sensors is very diverse, so before purchasing, please familiarize yourself with the technical parameters of the sensor.
You can connect, among others, to the Arduino microcontroller: a sensor used in smart homes that detects natural gas, LPG and carbon monoxide. Flame, color, linear Hall effect, reflective infrared, distance, rotation, sound, temperature and air humidity sensors are also available. Other sensors that work with Arduino include soil moisture sensor, tilt (shock) sensor, ultraviolet sensor, liquid level sensor, fingerprint sensor and much more. All models available in the offer are in the Arduino sensors category.
