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

Despike/smooth data from a DHT22 with a median filter and display on a 0.96 inch OLED with the date and time from a DS3231 real-time clock!

Very simple air quality monitor with nice processing graphical interface oh PC monitor.

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

Remote temperature monitor using a Bluetooth module and an NTC thermistor. An Android app made with App Inventor is used to read data.

Nice looking weather station based on BMP180 and DHT11 sensor boards.

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!

This project will demonstrate how to build a water level monitor using an Arduino Nano, a Solu SL067 water level sensor, and an indicator.

Build a simple incident light meter for old meterless film cameras

Connect GPS and MicroSD Card to Arduino and log the GPS information - Quick and Easy

In this project, you can build and display a sonar system by using graphical programming software Kittenblock, developed based on Scratch3.0

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

Literally the simplest way to make a weather station!

I am back again with another Arduino based home automation project.

Create a burglar-tripwire with the ultrasonic sensor.

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

An automated humidor using an Arduino — with or without building your own humidor.

Copy colours from outside environment.

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.

Evaluate the amount of the energy generated by a solar panel at a given direction through light intensity levels.

Senses for smoke in the air near a 3D printer and will sound an alarm and turn off power to the printer if smoke is detected.

Connect Ultrasonic Ranger and MicroSD to Arduino, and program it to record the distance - Quick and Easy!
