Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor ...

Here we use PIR sensor and Arduino to detect the motion of a hand. This detection can be used to operate electronic equipment.

The detector can detect a small metal coin at a distance of 15 centimeters.

Smarter Home Energy Use with Open Source and Cheap Sensors.

Easy to build, but comparable with professional seismometers, homemade Arduino seismometer.

Let us predict the changes around us with Arduino

Pulse induction metal detector, built on the Arduino Nano.

A cheap DIY air quality monitoring device.

Pulse induction Metal Detector. It can detect a metal coin at a distance of 15 cm and a larger metal object at a distance of 40 cm and more.

DIY Arduino air quality monitor which can measure surrounding air quality also shows temperature and humidity in your room.

It is hard to measure the height of the children. So, we made Height Measure using distance sensor VL53L0X.

Simple data logger that stores electrical data (voltage, current, power, energy, etc.) in an SD card, with timestamp for later analysis.

This is a very precise scale for any weight up to 1.5 kg!

Arduino Nano and Visuino: Plot BME280 Temperature, Humidity and Pressure on Nextion Display Scope - Quick and Easy

Fan PWM controller with temp sensing and max speed button override

It can detect metal coin at 15cm +, and bigger metal objects at 50cm and more. Also capable of discriminating between ferrous and nonferrous

The lightmeter based on Arduino as a main controller and BH1750 as a metering cell. Information is displayed on SSD1306 OLED display.

An Arduino based device to monitor the levels of combustible gases, carbon monoxide, relative humidity and temperature in the kitchen.

Power monitoring, appliance detection using Arduino and save data into a Text file, Google Sheet for creating graphs and analysis.

A low cost air quality monitoring device created with an aim to detect pollution hotspots caused due to traffic jams or factory emissions.

An interesting way to increase sensitivity and reduce the noise of the ADXL335 analog accelerometer.

In this tutorial I will show you how to make gas leak alert security alarm using arduino nano and mq 5 gas sensor

A cube with all the necessary sensors, suitable for a wide range of applications like agriculture. Know the land beneath you!

A simple device that makes controlling humidity and saving energy a snap. Operates as easily as a thermostat.
