An Arduino based device to read multiple DS18B20 sensors and send the values through a RS232 connection to a domotica system.

Build an Arduino heart rate monitor with a MAX30102 sensor and a 16x2 LCD.

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

Create a burglar-tripwire with the ultrasonic sensor.

It can measure fine dust, humidity, temperature and CO2 concentration in the air and check it on the internet in real time.

This device measures fine dust and NO2 concentration in the air while on the move and adds GPS coordinates to each measurement location.

As the title says, this is a pretty simple PIR motion controlled relay using an Arduino Nano.

Portable distance detection device using an Arduino and an ultrasonic sensor.

Build a simple incident light meter for old meterless film cameras

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

Just before creating my next tutorial, which will be using a PIR sensor, I thought I might create a separate tutorial for PIR Sensor.

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

How long were we released from the gravity of the Earth? This machine measures how many seconds we are zero gravity state.

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

The ElectronicsLovers Tech Team built this module, which has one difference from a usual one: it’s digital.

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

In this tutorial I am going to show you how to build a Wireless Weather Station with a big 3.2" Color TFT display using Arduino.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

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

Ultra low-cost flow-through photometer for on-line measurements of bacterial density.

During the summers, many people get sunstroke because of playing in the sun for too long. So this device will prevent getting sunstroke.

Build a weather station with Arduino & ASP.NET Core.

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

If the temperature measured by DS18B20 is above the predefined threshold, it turns the fan on automatically unless the piezodisk is pressed.
