    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

    Received in good order and on time. I love when you guys use Buffalo logistic, they are quick. I haven't tested it but looks good so far.
