This tutorial will explain how you can measure distance with the HC-SR04 Sensor. In the upcoming text, we will explain how the sensor works and give example sketches for your Arduino Board. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object. It will measure the distance…
Read MoreWould like to measure the darkness of a room? In this sensor tutorial, we will show you how by using an LDR sensor. It is a very simple tutorial that shows how to measure the amount of light present in a room. In order to detect the intensity of light…
Read MoreIntroduction The capacitive touch sensor (TTP223B) is a touchpad detector which offers 1 touch key. The touching detection is designed for replacing traditional direct button key. The touch sensor can be used for various projects. The sensor is essentially a button style sensor that detects when it is being pressed.…
Read MoreIn this sensor tutorial, we will use one magnetic door switch and an LED for detecting if a door is open or not. In a normal state, the reed is open. There is no connection between the two wires. One half is a magnet. When the magnet is close to…
Read MoreIn this sensor tutorial, you are going to learn some basics about Infrared Sensors, IR sensors. You will learn how to use the IR sensors and send values to the Serial Monitor. There are a couple of variants for the IR sensor. There are IR sensors with three or four…
Read MoreIn this tutorial you will learn how to measure if something is tilted or shaken. Tilt sensors are designed for this. The most common tilt sensor is a ball bearing in a box with contacts at one end. When the box is tilt the ball rolls away and the contact…
Read MoreIn this tutorial, you will learn how to measure temperature and how to send that information to the Serial Monitor. The TMP36 series are precision integrated-circuit temperature devices with an output voltage linearly proportional to the Centigrade temperature. TMP36 is three terminal linear temperature sensor. It can measure temperature from…
Read MoreIn this tutorial, you will learn how to read the values from a soil moisture sensor. So, soil moisture sensors basically measure the content of water present in the soil. If you are building a smart garden that waters plant this sensor is ideal for reading the wetness of the…
