Sensors help to measure various physical phenomena and quantities in the form of an electrical signal understandable to the controller. No interesting project is complete without sensors for the Arduino. Sensors give the controller a number of specific “senses” to navigate in space, measure temperature, ambient pressure, gas concentrations, and other parameters. Build your mobile robot or smart home!
A blinking check engine light and rough running engine got you down? I replaced the camshaft position sensor, but your ride isn’t running. Don’t worry; we’ve got your back. Replacing a failed cam sensor is just the first step in getting your engine purring again. You must do a few critical things after the repair …
Recently I wrote about linear encoders, and in this article, I’m going to tell you about optical encoders. An optical encoder is a motion sensor based on an LED and an infrared receiver element between which a disc rotates, divided into translucent and opaque zones. Purpose Optical encoders are used to determine parameters such as …

A linear encoder is a sensor for monitoring movement, position, or speed along linear axes. The movement of the readout node relative to the scale generates pulses that report the movement information to a receiving device. These devices are called linear devices because they are used to measure the linear movements of an object. This …
When your car is turning in a narrow alley, you can hear the parking sensor warning you that there is an obstacle behind you. It recognizes the presence or absence of objects thanks to an ultrasonic distance sensor. What is Ultrasonic? Ultrasound is sound waves that travel through space. What makes ultrasound different from the …
DHT11 and DHT22 sensors are very popular in the Arduino environment and are often used in weather stations and smart home projects. In this article, we will learn how to use these sensors, how to connect to Arduino Uno, Mega, or Nano boards correctly, and which libraries to use for writing a sketch. These sensors …

Another useful device that is often used in modern devices is a temperature sensor. Even your computer has several temperature sensors, with which the system monitors the overheating of key components – processor, graphics card, power supply, and other components. The most popular example of a home temperature sensor is a thermostat. It is a …

Arduino ultrasonic distance sensors are very much in demand in robotics projects because of their relative simplicity, sufficient accuracy, and availability. They can be used as devices to help you avoid obstacles, get the dimensions of objects, simulate a room map, and signal objects’ approach or distance. One common option for such a device is …
The weight sensor is a very important element in many Arduino projects. By changing the weight, you can recognize the mass and track and record changes to the object and then perform some actions. In this article, we will learn how to connect a weight sensor to an Arduino using load cells of various denominations …
