Smoke And Gas Detector

Smoke Detector with Arduino & MQ-2 Sensor Welcome, In this Blog we will simulate how to use the gas sensor, to detect the presence of a toxic gas, or smoke, in a given location. we will process and display the results, using an LCD display and 2 indicator lights. Components Used: MQ-2 Gas sensor Arduino LED 16*2 Breadboard Connecting wires Led Bulb (Red and Green) In this project the MQ2 gas sensor is used for the detection of gas leaks for equipment in the consumer and industrial markets. This sensor  detects LPG, i-butane, propane, methane, alcohol, hydrogen and smoke. He has great sensitivity and a quick response time. his sensitivity can also be adjusted by a potentiometer. it has two outputs: analog and digital, for this project we use the digital output. Open Proteus, new project, you can name it gas sensor, find a place to save it, choose a default project, and follow the steps. Open the component library, search for Arduino Uno, or any other , if you can't find it, you ...

Automatic Water Tap Control

Automatic Water Tap Control System Using Arduino Hello, viewers welcome to our new project demonstration.The project title is automatic basin tap control system using Arduino with IR obstacle sensor. The project have another part which is detect the motion and control the light automatically.  Let's see how it is made.  Components list: * Arduino Nano * 16*2 LCD display * Water Tap * IR Sensor * 10k potentiometer * PIR Motion Sensor * 5v LED light * 12v Dc water pump * 12v transformer * BC547 Transistor * 4*2 Battery * On/OFF Switch * 10k Resistor * 100ohm resistor * Veroboard * Some Jumper wire For making this project single Arduino nano-board, 16*2 LCD Display. This is a PIR motion sensor and 5v LED light.The power switch for the circuit. This is another PIR motion sensor and 5v LED light. Here we supply the power using two 4V batteries. This is the rectifier circuit with 12V Auto Dc Transformer. Here we connect the 12V dc water pump motor. This IR obstacle sensor and water ...

Digital Keypad Security Door Lock

Digital Keypad Security Door Lock using Arduino Hi everyone, welcome to another blog tutorial,in this tutorial I will teach you how tomake this password enabled entry. Components: 4X4 matrix keypad membrane keypad 16X2 LCD Arduino Servo Motor Connecting Wires Potentiometer Circuit Diagram: Description: I'm using as an improvised enclosure and this is the door, this is a 4X4 matrix keypad, membrane keypad, this is a 16X2 LCD.So, what this system does is this, like I said it’s a password enabled entry, so, I programmed the system with Arduino, so,when you enter the wrong password using this 4 by 4 matrix keypad the door will not open and the password you entered will be displayed on this LCD, but once you enter the right password, the door will open, then it will remain open for 5 and then close. So, the components or for the parts I usedin the design you can see here I have a motor driver this is a motor driver to drive the motor that opens and closes the door, this is a potentiomet...

Wireless Weather Station

Wireless weather station u sing Arduino   Dear friends welcome back! Today we are going to build a wireless weather station project using Arduino.Without any further delay, let’s get started!  A Wireless Weather Station with a big 3.2” Color TFT display. The project is up and running,and it displays the current date and time, the indoor temperature and humidity, and the outdoor temperature and humidity. The readings of the outdoor sensor are updated every second in order to demonstrate that we have a reliable communication link established with the transmitter which is outside at a distance of 5m. The readings of the indoor sensor are updated once every minute. The heart of the project is the fast Arduino Due, there is no flickering of the screen when the values are updated. Let’s now see the transmitter.  The transmitter is much simpler. It consists of an Arduino Nano, a DHT22 sensor and the NRF24L01 wireless transceiver module. The transmitter reads the temperature and ...
