Add extra layer of security to your ATM machine transactions with biometric fingerprint and OTP SMS.

This is an Arduino Uno with a DHT11 temp/humidity sensor with and LCD screen powered by a power bank.

This tutorial will show you how to use DHT11 with Arduino.

Move your hand around - lights ON. Move hands over that again - lights OFF. Cool, right?

In this tutorial, you will learn how to calibrate and use MQ9 gas sensor with an Arduino board.

I will explain how connect Arduino with Vibration sensor and LED.

This Instruction will show how to make a box which can indicate temperature and humidity with Arduino

Soil moisture sensor which gives you LCD display of percentage of moisture.

This project is based on Arduino radar (HC-SR04) which is digitally visualized using Processing.

This project will attempt to show how much alcohol is in the air (semi-quantitative measurements).

Make a Ultrasonic Range Detector Using Arduino and SR-04F to measure any distance without using rulers with this simple tutorial.

I'm going to show you how to make an LCD thermometer with an Arduino UNO and a LM35/36 analog temperature sensor.

How much time do we waste in traffic jams? I made an Arduino-powered destination notifier to utilize this time in a productive way.

I built an Arduino Weather Station. It uses a DHT 11 (it will also work with DHT21 DHT22).

MQ2 Sensor is a gas module and it is suitable to detect Hydrogen, LPG, Smoke, CO, and Alcohol. It has high sensitivity and fast response.

The objective is to find an easy way to implement RS485 on an Arduino Uno, then to adapt it to an ESP8266.

ESP8266-01 and DS18B20 temperature server.

Simple Temperature Monitoring with DHT22 & Arduino.

This project will show you how to make a probe using a datalogging Arduino shield, some sensors and an RTC.

In this tutorial, we will learn how to detect Smoke and inflammable gases using an MQ-2 sensor.

This project is a good learning project to get comfortable with soldering and programming an Arduino.

This little project will show you how to use a soil moisture sensor.

With the help of this project, users can preset a desired number of times the pressure cooker whistles before they're alerted accordingly.

Predictive maintenance of industrial motors using high precision 3D magnetic sensor TLV493D-A1B6.
