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

Very simple station that shows: Temperature, Humidity, Heat index, Carbon Monoxide, Alcohol, Carbon dioxide, Toluene, Ammonium and Acetone.

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

Build a simple incident light meter for old meterless film cameras

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

Use a ratiometric linear Hall effect sensor to build simple magnetic field strength meter.

We can measure body temperature without contact with this device.

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

Better code for the MMA8452Q

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

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

You'll learn how to make a luxmeter with Arduino and BH1750 Module.

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!

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

Create a burglar-tripwire with the ultrasonic sensor.

Literally the simplest way to make a weather station!

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

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!

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

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

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

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

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