Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

Using an LCD1602 display, the approximate distance to the nearest object is shown. If an object or person crosses the sensor and reflects the ultrasonic waves, it triggers an alarm sounding off a ...

By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer. So what is it ?

Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security purposes.

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got ...

In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed.

The traditional single sensor alarm system has been difficult to meet the requirements of multiple pollutants detection at the same time, so this research proposes a multi-sensor integrated ...
