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

Smarter Home Energy Use with Open Source and Cheap Sensors.

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

Let us predict the changes around us with Arduino

In This Tutorial, I will Show You How to Make an Arduino Based MPPT Charge Controller

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

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

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

Pulse induction metal detector, built on the Arduino Nano.

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

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

Control the temperature of the rooms you are actually in

Portable range/distance detection device using an Arduino, ultrasonic sensor, and buzzer.

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

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

Use the cheap Fiagro TGS4161 Sensor to monitor CO2

This coaster detects the temperature of a cup. You get a signal when it is ready to drink.

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

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

Intelligently reduce the moisture in your basement/crawlspace to help control mildew growth and lower your heating/cooling bill.

The HMC5883is a digital compass designed for low-field magnetic sensing. This device has a wide magnetic field range of +/-8 Oe.

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

A digital stadiometer for human height measurement.

This project consists of a set of proximity sensors with a haptic interface to alert the user to the presence of objects around them.
