OK sensor
AZDelivery is my go to for small smart electronics projects and these sensors were no different. Cheap and seems accurate in most situations. In close quarters though it does get a bit choppy, however is good enough to detect the level of salt in my water softener.

Sensors to see
Good bargain for these five sensors, great for robot like project fast delivery,

They do what they're supposed to.
These Ultrasonic distance sensors works fine. Easy to operate using the Adafruit libraries in CircuitPython. They give an approximate range, but don't expect anything too accurate. The distance measured depends on the shape of the object the sound is bouncing off. Angles and curves will change the measurement. But if you are wanting to know is something is in the way, or if an object has gone past the sensor, these will work. If you want something millimeter accurate, use LIDAR.

Werken prima en vrij nauwkeurig, bereik wat beperk tot ca 160 cm.

AZ-Delivery est une référence dans les cartes pour l’Arduino. Sa qualité et son service après-vente sont exceptionnels. Je recommande ce produit sans hésitation. Testé dans l’heure qui a suivi la réception de mon article et en utilisant son e-book, tout a fonctionné dès le premier essai. Monté tout d’abord sur les ports donnés dans le sketch puis déplacé sur le port à 50 broches de ma Méga. Je suis vraiment content de mon achat. Je recommande la marque sans hésitation.

Funzionano bene, precisi nella misura.

Der Sensor lässt sich mittels IDE am Arduino recht einfach programmieren und auch das verdrahten ist nicht allzu komplex. Die Messwerte sind zwar nicht ganz genau aber sie bewegen sich in enger Toleranz von ein zwei Zentimeter.Das ist für Parksensorik vollkommen ok und auch für industrielle Anwendungen wo man nicht unbedingt Millimeter genau positionieren muss in Ordnung. Er detektiert schnell und zuverlässig insofern man das Programm gut gelöst hat😂Delays gehen da gar nicht.
