How to monitor Sensor values in Blynk App using Raspberry Pi
Hi guys, in this article we will discuss how to monitor the DHT sensor values in the Blynk application. For this we should have an account in the Blynk app, we can signup into Blynk either by Gmail or Facebook. After signup create a project with text labels, and we get an auth key to…
How to display DHT sensor values on GUI application in raspberry pi
Hi guys, this article is to read the DHT sensor values temperature and humidity, these values are displayed on the PyQt5 GUI application. This GUI is designed in Qt designer (see below image) and converted to the .py file. DHT11 is a temperature and humidity sensor. This sensor has 3 pins (VCC, OUT, and GND).…
Posting Sensor Values to the Server using WiFi Module with Arduino Uno
Introduction: In this tutorial, I am going to explain about sending sensor values to the thing speak server. ThingSpeak is an open-source server, so users just need to sign up with your email id. After sign up creates a new channel to get an API key, this key is unique for every channel. By using…
How to Interface MQ 2 with Arduino
Introduction: MQ 2 or MQ6 is Gas leakage sensor which consists of 4 pins. This module is used to detect the gases like butane, propane and LPG. VCC – 5v DC GND – ground D0 – Digital out A0 – Analog out Requirements: Arduino UNO – 1 MQ2/MQ6 – 1 Jumper Wires Working: If no…
How to Interface DHT 11 with Arduino
Introduction: DHT 11 is a sensor which gives temperature and humidity of the air molecules. It is an 3 pin Module. VCC – 5v D0 – digital out (sensor values transmit from this pin) GND – ground Requirements: Arduino UNO – 1 DHT11 – 1 Jumper wires Working; D0 pin is treated as input and…
How to Interface IR Sensor with Arduino
Introduction: IR sensor module will have 3pins VCC, GND and D0 respectively. VCC – +5V DC GND – Ground D0 – Digital Out Requirements: Arduino UNO – 1 IR Module – 1 Jumper Wires This module consists of two leds (looks like led but not an led), one is IR Transmitter (i.e., white one) and…
How to Interface Ultra sonic sensor with Arduino
Interfacing Ultrasonic sensor with Arduino UNO HC-SR04 As show in the figure HC-SR04 is an ultrasonic sensor. It is an 4pin module consists of Vcc, Trig, Echo and GND. Module had a transmitter and receiver which transmits and receive the ultrasonic wave signal. Pins Explanation: VCC – +5v dc TRIG – To activate sensor we…
Led Blinking and Fading using Arduino
Led Blinking: We will see blinking an normal dc led with arduino. Requiremnts: Arduino UNO Board – 1 No. LED – 1 No. Potentiometer – 1 No. Breadboard – 1 No. Below program is to blink an led with delay of 500msec of time: #define LED 10 void setup() { pinMode(LED,OUTPUT); } void…
How to do Arduino Coding for beginners
In Arduino, we can do coding in C and C++ languages. We will discuss how can code in C++ language and some basic predefined functions in Arduino Code structure will be as follow: The above program is an example of led blinking of 1 second. Predefined Functions: Some of the predefined functions are:pinMode(pin,mode);digitalRead(pin);digitalWrite(pin,value);analogRead(pin);analogWrite(pin,value);pulseIn(pin,value);delay(ms); pinMode(pin,mode): Configures…
