Features

  • Ultrasonic hc-sr04 distance measuring transducer sensor, it consists of ultrasonic transmitter, receiver, and control circuit.
  • HC-SR04 Ultrasonic Sensor Distance Module: using IO trigger for at least 10us high level signal,When triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.
  • Hc-sr04 Test Distance following formula: L = 1/2 × T × C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed)
  • Power Supply : 5V DC; Quiescent Current : <2mA,; Effectual Angle: <15° ; Detection Distance : 2cm~450 cm; Resolution : 0.3 cm

SunFounder HC-SR04 consists of ultrasonic transmitter, receiver, and control circuit. Mode of Connection: VCC/ trig(T)/ Echo(R)/ GND (VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output.)

Eccellente By Michele 2016-07-07 17:31:09

Avevo bisogno di un sensore di distanza economico e affidabile, ho così provato i classici sensori IR ma li ho trovati imprecisi ed inaccurati! Sono passato al sensore US e sono molto soddisfatto, estremamente preciso e accurato. Facile da montare e ben costruito, ideale per smanettoni!!

Nulla da dire sulla spedizione e l'imballo, sufficienti.
Testati con Arduino Mega funzionano, anche se devo capire bene come ottimizzarne la risposta, in quanto a vuoto sfarfallano un pò troppo. Probabilmente i due occhi devono essere in qualche modo schermati.
Il prezzo direi che è ottimo rispetto altri fornitori..

また、こちらの商品は、きちんと、導電ビニルでパッケージされ箱入りです。ちゃんと商品として扱っています。 By Gary 2016-06-29 17:09:11

サインスマート社の古い同じ型番の商品が欲しかったのですが、見当たらないので、こちらのブランドのプリントされたものにしました。2っ穴のサインスマート社の最近の商品は、計測中、条件によってフリーズします。こちらのは、とりあえずフリーズしませんでした。古いサインスマート社の商品と同じ挙動をするとは言えませんが、フリーズしないだけで良しです。フリーズは、プログラムで対処できません。ハードを追加しないとなりません。

It works great and has pretty good range. By random 2016-05-24 16:22:36

Awesome. Once this arrived it took me 10 minutes to finish my first robot.

As for the accuracy, it seems to only be slightly less accurate then the Parallax Ping Ultrasonic Range Sensor. I got both to test them out. These are pretty great for the price. Give em a try. By MrMe 2016-05-11 14:24:21

These guys are working pretty well. Sometimes their are some connection errors, but it may be human error. I do not have proper connection pins for these guys and can't always tell if they are properly wired. They work well when they work though.

My four year old daughter thinks the thing is like Wall-E, which, of course, makes me super happy By Michael D. Messmore 2016-05-11 14:22:41

I'm using this with a raspberry pi on for a rover and they work excellently. Incredibly easy to program for and accurate as well. They are well made, and don't have the awful solder joints I've seen on other inexpensive products with through the hole components. I would recommend this to anyone doing a raspberry pi or Arduino project requiring range-finding or distance measurement for large enough objects. Plus I love the fact that it gives my rover that quality of having "eyes" to make it a little more animal like.
