How to make a bluetooth datalogger for temperature and humidity using Arduino MEGA.

Leave a Comment / Arduino, Datalogger / electronics guru

What is a data logger for? A data logger is an electronic device which acquires physical parameters (for example temperature, humidity, atmospheric pressure, pollutants, etc.) in precise time intervals and saves them on a permanent memory device (such as an SD card) or transmits them to a cloud platform to be processed and displayed.

Thermo-hygrometer with clock and LCD display on Arduino UNO

Leave a Comment / Arduino / electronics guru

What is the thermo-hygrometer used for? A thermo-hygrometer is a device that measures ambient temperature and humidity. These two parameters are measured by a special sensor at regular time intervals. They can then simply be viewed on a display or stored on an SD card (in order to have a history) or even sent to

Ultrasonic distance meter with LCD display on Arduino UNO

Leave a Comment / Arduino / electronics guru

Introduction In this tutorial we will see how to make an ultrasonic distance meter. Ultrasounds are acoustic waves having a frequency higher than that audible by humans. The medium crossed by the ultrasounds conditions its propagation speed. They are slower in gaseous media and faster in solid media. In air the speed of propagation is
