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

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

Professional quality wireless weather station.

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

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

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

eNVIRO is an advanced weather station with remote sensor.

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

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