    This module will be used for presence detection activating a ventilator when the room temperature is over 22C. This is made possible when you connect this sensor to a esp board and integrate this with Home Assistant where the automation is created and maintained. This module is of high quality and I would recommend it to everyone.

    Tested positively until 3 meters, using Arduino's "NewPing" library, good precision. Mounted on a known distance, it can be used to measure sound's actual speed in the given air's temperature and humidity. Distances are meant from the forward border of the ultrasonic capsules: in the image, an example on 10 cm. Provato senza problemi fino a 3 metri di distanza, usando la libreria di Arduino "NewPing", con discreta precisione. Montato su una distanza nota, si può usare per misurare la effettiva velocità
