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.

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

A super smart buoy with lots of sensors that sends data over radio to a base station where it is displayed on a real-time dashboard!

Professional quality wireless weather station.

eNVIRO is an advanced weather station with remote sensor.

This is a low cost, modular smart board with wireless capabilities.

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

Kayaking GPS: speed, time, latitude, longitude, distance and azimuth to waypoints, odometer, tide clock, battery monitoring.

A tech high-school student-teacher team from Uruguay developing High Altitude Balloons for science! IN ACTIVE DEVELOPMENT!

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

Geiger counter measuring radioactivity using Arduino Nano in 3D-printed housing, with OLED display and Li-ion battery.

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

The ball and beam system is laboratory equipment with high nonlinearity in its dynamics and PID control.
