Interfacing Rain Sensor with Arduino

In this article we are going to explain about interfacing Rain Sensor with Arduino. The rain sensor module is an easy tool for rain detection. It operates as a switch when raindrop falls through the raining board and also it measures rainfall intensity. The module features, a rain sensing board and the control board that is separate for more convenience, power indicator LED and an adjustable sensitivity though a potentiometer. Rain Sensor Module Raindrop sensor is basically a board on which...

Interfacing Soil Moisture Sensor with Arduino

Introduction In this article, we are going to interface a Soil Moisture Sensor with Arduino Uno. We will measure the moisture content of soil in pot or farming field and by using this we can pour water into field based on preset values. This sensor measures the volumetric content of water inside the soil (based on resistance/conductivity) and gives the moisture level as output. The sensor is equipped with both analog and digital output, so it can be used in both...

Interfacing GSM Module with Arduino

In this article, I am going to explain about interfacing of GSM Module with Arduino. Interfacing a GSM module to Arduino is pretty simple. We have to make only 3 connections between the GSM module and Arduino. For the working demonstration we will be sending an SMS to a particular number whenever a switch is pressed. Components Required Arduino Uno GSM Modem Switch 1kΩ Resistor Breadboard Connecting Wires Hardware Circuit Diagram Interfacing GSM Modem with Arduino - Circuit Diagram Connections Connect TX pin of GSM Module...

Interfacing PIR Motion Sensor with Arduino

A PIR sensor is generally known to the world as a motion sensor or motion detector. So in this project we are going to use the PIR motion sensor to detect motion. Here we are going to sense movement of human by using Passive infrared sensor (PIR sensor). Using the feedback from the sensor we will control an LED with the help of Arduino Uno. Components Required Arduino Uno PIR Sensor 330Ω Resistor LED Breadboard Connecting Wires Hardware Circuit Diagram Interfacing PIR Motion Sensor with Arduino -...

Interfacing GPS with Arduino

GPS stands for Global Positioning System. GPS module find the location (latitude, longitude, altitude) by comparing the time taken for receiving signals from satellites in its vicinity. GPS offers a great accuracy and also provides other data besides position coordinates. Components Required Arduino Uno GPS Breadboard Connecting Wires Hardware Circuit Diagram Interfacing GPS with Arduino - Circuit Diagram Connections Connect TX pin of GPS Module to pin number 4 of Arduino Uno. Connect RX pin of GPS Module to pin number 3 of Arduino Uno. Connect Red...

Interfacing MPU-6050 / GY-521 board with Arduino Uno

About MPU-6050 MPU-6050 is a chip manufactured by Invensense which combines 3 axis accelerometer and 3 axis gyroscope with an on-board digital motion processor. It also includes a embedded temperature sensor and an on chip oscillator. It is very accurate and consist of analogue to digital conversion hardware for each channel thereby capturing x,y,z channels at the same time. The arduino can be interfaced with I2C bus. 3-axis Gyroscope The MPU-6050 consist of a 3 axis gyroscope which can detect rotational velocity...

Interfacing Ultrasonic Sensor with Arduino Uno

In this tutorial we will learn about integrating HC-SR04 ultrasonic distance sensor with Arduino Uno. Ultrasonic sensors are commonly used for obstacle detection and distance measuring applications. The sensor works on the same principles of a radar system, which converts electrical energy into acoustic waves and vice versa. The HC-SR04 ultrasonic sensor is based on the principle of SONAR, which is an abbreviation of Sound Navigation Ranging. This sensor is used in many hobby projects where there is a...

Interfacing Servo Motor with Arduino Uno

In this tutorial we will learn how to interface servo motor with Arduino Uno. Servo Motor is an electrical linear or rotary actuator which enables precise control of linear or angular position, acceleration or velocity. Usually servo motor is a simple motor controlled by a servo mechanism, which consists of a positional sensor and a control circuit. Servo motor is commonly used in applications like robotics, testing automation, manufacturing automation, CNC machine etc. The main characteristics of servo motor...
