    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.

    je ne peux pas encore commenté sur sa durée de vie. mais ce produit fonctionne très bien pour moi l'image sur le site parrait plus grande mais sa s'adapte bien a mon projet. 2 point a souligné ; a 400m 9 reponse sur 10 est bonne si votre système n'utilise pas de batterie relier le GND a la terre sinon ca va vaciller.

    Giving 4 stars to quality because although this module is pretty good for the price far from 180-200cm it starts being very innacurate. But anyway very happy with the product and shipping time. If you don't need too much precission in your project then take it low price and good quality according to it.

    For this kind of money, quality and the application of this Ultrasonic Module nobody can have any complains. It is really good to combine it with different Arduino projects, especially Arduino Robots.

    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. Tried without problems up to 3 meters away, using the Arduino library "NewPing", with discreet precision. Mounted on a known distance, it can be used to measure the actual speed of sound under the present temperature and humidity conditions. The distance is from the front edge of the ultrasonic capsules: in the image an example in 10 cm.

    Sensor ultrasónico para medición de distancias. Conecté el mismo con un ARDUINO NANO, y funciona a la perfección, el error en la medición es menor a un milímetro lo cual es despreciable dependiendo del proyecto al que se lo quiera aplicar, en mi caso es para detectar un objeto "estacionado" a 0,60 metros. PERFECTO.

    La parte metálica de uno de los sensores viene estropeado. A falta de probarlo, no volveré a comprar a este vendedor.
