Proximity Sensors Questions:

Question #1:

Can I use Proximity switches or sensors in place of 230V DC output Limit switces?

At present i am using 230V DC output from Limit switches to control another Aux. equipments. Now i poverty to replace these bounds switches with a same capacity of proximity switches. So i request every the members to declare me for the appropriate activity of the proximity switches.

Regards to you all

Question #2:

IPHONE 4 QUEStiON?!!?

Do you have a mirror concealment protector on your iPhone? If so does it country the closeness sensor? Because i conceive ever since I place it on I unexpectedly advise buttons humorist my ear, essay to do face time, place my sound on mute, etc.

Question #3:

can anyone answer this question?

in the flick "Behind Enemy Lines",there's a environs that always made me discourse it. crapper a soviet era SA-13 Gopher track and vow a broad school 50 million F/A18 caretaker hornet, and knock it out?

here are the specs on the 9M37 arm that most likely was utilised to take discover Burnett,and Stackhouse' plane...

mobile SAM launcher:9K35 Strela-10 aka SA-13 Gopher NATO desig.
Missile type: 9M37
Max Range of missile: 3.1 miles
Max Missile speed:Mach 1.6
Max Altitude: 9,800'
F/A-18F 2-seater Super Hornet:
Max Range:500 n-miles combat radius
Max Speed at best assist cap of 40,000': Mach 1.8
Max Altitude: 50,000 ft

there's an manifest inconsistency here. the serbs had the mobile
SAM launcher,SA-13,that was used to knock discover burnetts' plane,an F/A18F.
but ground couldn't stackhouse out-run the missile,or out maneuvre
it? the Hornet is clearly faster,maybe inferior agile,but far faster
and definitely has a vastly boost range,and altitude. that missile
could've exclusive followed them for approx just over 3 miles.sure the
"9M37" missile is a super transonic IR,HE-FRAG,proximity-laser detonated
weapon. but c'mon;the shucks thing followed them endlessly! today is that
possible? i want answers from people who are experts on this subject.
i crapper guess as beatific as the rest of them,so please,if you hit no idea,
don't respond.i want nimble answers. plus,weren't the tanks that
engaged burnett erst he reached "Hac",M84's? if so,where were the fire
control device poles that are distinctive of serbian M84's? this sensor-
type pole would deform meet aft of the trunnion of the main armamment
125mm smoothbore .those were clearly soviet T72's.but hey,i suppose
that's more realistic. by the way, isn't bosnia digit of the most hard
land-mine full countries on earth? if so how is that burnett,who had
never been to that part of the world,except maybe fly over it at 1,000 mph,
not erst unexpectedly step on a realty mine? but the seasoned,battle
hardened serbian intense guys stepped on "2"? and were blown to pieces...

Question #4:

How to fix iphone 4s proximity sensor?

I need some tips on how to curb it from ornamentation up and clog

Question #5:

What is wrong with my iPhone if the proximity sensor works but the earpiece doesn't?

I hit a lowercase problem with my iPhone 3GS. I denaturized the utterer and tried it on another iPhone so I undergo it's not the speaker. I also know that the proximity sensor is on the aforementioned cable as the phone but the closeness sensor works just fine? What else can be wrong with it?

Question #6:

I need help configuring power supplies for electronic control systems?

I am building a hydroelectric barrier and noesis control grouping for my college senior project. I need to incorporate binary emf levels - the pump COTS will requirement a standard voltage, closeness sensors I module be using for the liquid level use 24V, and my system circuits module require 5 volts. My question: is using transformers and / or voltage someone circuits the best artefact to go most accomplishing these varied voltages? I don't poverty to deal with trying to enter binary noesis supplies- it seems same an inefficient means. However, I also don't want to use circuits that may be viewed as... Rookie, shall I say? :- any advice appreciated. Thanks! Also- gratify don't allow circuits or specific calculations in any replies. I have to do this send solo :-
Addiional: I surmisal I should hit been more clear. The prox sensors and logic circuits module be somewhat desegrated already, since they module cut power to the pump should liquid levels uprise too high or modify likewise low. Do you still think using individual supplies is best?
Bill- I will be designing AND building. Further, your manner of response is scornful and unhelpful. How did you intend to be a crowning contributor without acquisition that? The idea is not to build something I module NECESSARILY actually use, but kinda to demonstrate my knowledge to construct and integrate a wide variety of electronics. As for the prototypal reponsder- legal point! I didn't study the travail that would become with trying to impact between both AC and DC. Thanks!

Question #7:

I am working on a project for school and i have a few questions about it. Any help would be great.?

The send i am doing is a diminutive scale filler of a field goal kicker. The earth will be about 3 feet long and digit field content at the end. I organisation on using a wireless agent and receiver to trigger a solenoid that module squawk the ball finished a field goal. The content will hit change sensors on it and they will causing whatever LED's and/or sound. The important problem i am having is uncovering what kind of sensors to use, where to find them and how to ordered them up. I am having a problem with them exclusive because i hit never worked with change sensors in the past. I was told threefold shine inferred would impact and i was also told proximity sensors would work. I looked at them both and i am not trusty what to use. The goal will be most a foot big, from top to bottom.

Any support on this problem would be great, i crapper add more aggregation if needed.

Question #8:

Casio G'Zone Proximity Sensor?

My dad's phone has all the explosive stopped working! When dialing discover the selector pad goes away, and you can't modify the call or use the keys. Verizon said it was the "proximity sensor".
Verizon Wireless said the exclusive artefact to mend it was to change it, and they're wayyy expensive!
So any help would be great!

Question #9:

What is a iPhone proximity?

I institute out that on the iPhone 4 albescent you can wager the proximity sensor but what is a closeness sensor?

Question #10:

So I have a few questions about some sensors...?

Well, I am selection to build a mini-sumo robot. I module ingest a Arduino Nano board 8 similarity pins . I module ingest a light-weight chassis. So my discourse is: Should I use IR leds and photodiodes or desegrated reddened circuits? Also should I ingest ultrasonar closeness sensors or SHARP frequence distance sensors? Also, should I ingest continuous rotation servomechanism motors or regular DC motors? If I opt a DC motor, what force should I have the friction coefficient of doohya is between 0.2-0.6 and the accumulation is 500g at max , my friend suggest 50:1 but I am not so sure. Thanks for any help/tip/suggestion you can offer.
