This is a manual and automatic irrigation system

The “Bubble-Logger SPIEDEL” is an Arduino based floating hydrometer there monitor your fermentation for beer making.

This is an updated version of the fire alarm I made. it includes a gas sensor and an app for control

This circuit measure the water level of a tank and wirelessly send it to a receiver where it is displayed using a LCD display and LEDs.

This device allows you to record current, voltage, and power values onto an SD card. Recorded data can help to create useful graphs.

Consistently individuals bring about an enormous loss of property a life because of fire and blasts. Fire being one of the savage component

Simple and effective method (some police is using too) how to measure the side distance to an overtaking car.

Sniff-out the real tooter.

CO2 monitor and log based on MQ-135 with temperature and relative humidity correction.

Replicate a 3D environment in real-time!

After talking to a friend about his electric tricycle and how the window fogs up when it's cool out I thought it would be fun to monitor it.

6.4A-2uA current/voltage/power monitor based on the TI INA209 with extra GND usable as Arduino shield, FeatherWing, breakout or breadboard.

A really economic street lighting system.

This fully functioning Geiger counter was designed after the PKE Meter from the 1980s Ghostbusters movie.

In this project, use the YF-S201 1/2-inch water flow sensor to measure the water flow rate (L/min) and display it on an LCD.

Pulse induction metal detector, built on the Arduino Nano.

In this project I created a pretty simple digital level using a LCD screen and a gyro sensor.

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

Experimental system for Structural Health Monitoring (SHM), based on the Arduino.

Now we can check out the depth of the sea level by using a pressure sensor (MS5803–01 BA) connected to an Arduino, and display sensor data.

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

An automated probe that collect CO2 flux data on lake Mendota, WI.

Basic weather system, in/out temp and humidity with heat index, dew point, pressure and weather prediction and time and date.

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