Hi, I have just received this ultrasonic sensor and it has some of its little holes of the cilinders closed, it seems they are painted ??. Bad quality its manufacturing. I haven't connected it yet. Anyone knows if the readings will be affected? I thi
Hi, it is better to be installed by horizontal orientation.
Is this a expensive version of hr04? Or is something special/better on this module?
Hi, Ari. If you want a food safe water flow sensor. You should have look at this(http://www.seeedstudio.com/dep...
Hi Everyone,
I am starting a new project and wanted to apply this module. I have a very basic doubt that can I use these modules with boards other than Arduino, for example Radxa or some other development boards? Till now, I have just seen the appli
Hello, the output voltage level is about 4.5V(high) and 0.5V(low).
Hello
I need to learn how i can expand the range of the Ultra Sonic range measurement module
from 3cm-4m to 1-2 kilometer
Hi Robert, thank you for your suggestion, that is a nice idea! We will try to source it.
This one can't be expanded to a long distance.
Hey!can anybody help me with the mikro c code for this sensor to determine distance,
Hey,Thabo.You can download the library for this sensor from the following link:http://www.seeedstudio.com/wik...
Hi. I'm using the sensor for an outside application. Inside it works quite well, but outside not: It messures 0cm. We now have temperatures around 0°C outside here. I also have this problem after putting it in the freezer. Could there be a problem with
Hey Wenzel Reichmuth.Please pay attention to some situations: The dazzle of the spotlights and low temperature may cause fault and can not work.
Yeah, it is made of nylon with fiber that can be used in the salt water.
Hello. My sensor doesn't meter more 4cm..I looking for it on display..so than distance _4cm it's ok..than haven't barrier sensor shows only 4cm everytime..Why it csn be? and What can I do? Thaks
Exuse me, but where I can found this file?
What is returned when an object is closer than 3cm?
Hi Bob, it will return nothing since the receiver dose not receive any signal from transmitter.
Hi Will Gysi.Now we have no more sensitive water flow sensor,sorry for that.Maybe you can put a post on our wish.
Using this on a breadboard hooked up to a Raspberry Pi A La Mode but I can't seem to get it to report any distances greater than 5cm. Less than 5cm reports fine but as soon as I moved the object out past that it doesn't register. Max uS is about 250us.
"A La Mode"is actually a compatible Arduino that runs Arduino code. I tried using the Ping example supplied with the Arduino IDE but got the results I posted above. I'm just using the Raspberry Pi to run the Arduino IDE.
It is not possible for this sensor.
Can I use it in a humid room? (in the bathroom, for example?)
yes , it can be used in a humid room , but high humidity will influence influence the measuring accuracy.
