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 machine measures how many seconds we are zero gravity state.
