Hi all I am designing a robot to detect certain shapes on a floor using IR emitters/detectors.I was wondering if you could help me with these questions: ...
I want to use ultrasonic sensors for obstacle detection for my system. I m designig system which can help blind people to move around. I have downloaded one...
... You need to the modulation and demodulation, when you have to reject the ambient IR (e.g. from the sun). If you need to sense reflected IR from your IR...
Dileep, C2 and C7 are decoupling capacitors for ICs. Each should be connected to Vcc pins of the ICs with a short trace on one end and to the ground on the...
http://musclebiplane.org/htmlfile/beagle1.php We are trying to correct some obviously poor airflows through this engine cowling producing 430 degree cylinder...
Hi I'm kind'a new to this stuff. but wouldn't you want to mount heat sensors in multiple places over several flights to develop a crude map as to where to...
How about using temperature indicating crayons (like www.McMaster.com #3224K24) to tell you exactly what areas are getting how hot? You can easily check a...
I just had to comment, and give kudos to Sherpa---this is an excellant example of lateral thinking, and applying the best technology for the task at...
Hi everyone, I am doing a project on an automated irrigation system and ill need soil moisture sensors. I have been thinking to use gypsum blocks but it would...
Kurt I think, you don't need 2 sensors both behind and in front of the engine cooler. One (1) sensor in either place would give you almost as much information...
I want to measure the relative water content of the soil around the gypsum blocks.That is i want to monitor the water content of an area of cultivated soil for...
Hi all I am using infrared emitter/detectors for my robot project.I was wondering if anyone could explain to me the meaning of the viewing angle of the emitter...
The emitter and detector have to be able to see each other. Each has a viewing angle. If you start with the elements looking straight at each other, and...
Hi, all... I am planning to build a water jet which will come out with hot water pressure (3 bar, 90 celcius). My idea is to build a full weldded tank. Let say...
Hi der, Im making a Bot wid about 5 IR proximity sensors . But the problem is the IR rays of one transmitter output combine wid the recievers of the other Bot...
What is TSOP? Do you mean Thin Small-Outline Packages? The IR transmitters from your bot are interfering with other bots. This can be fixed by modulating the...
I felt I had to reply to this question. First, you are talking about building a steam pressure vessel. THis is a very very specialized skill, and is very...
I think a safer way to go would be a low pressure tank of cold water feeding a high pressure pump then heating the water on it way to the nozzle. This keeps...
HI guys. I've been learning PSOC from cypress.http://www.cypress.com/index.html I've got a idea for a project, an underwater AUV. but,I need some type of...
You need hydrophones, or underwater transducers. One thought that comes to mind for your application, is to salvage the barium-titrate transducers from a...
The transducer will be the problem. You want a short wavelength to spot small obstacles, like rope, but you want the transducer to be small in terms of...
hello everyone, i am making a robot that will face the solid as well as water below it. i have to identify both of them.please tell me the suitable sensors for...
I don't understand... What sort of solid? Are you trying to measure the thickness of ice? SherpaDoug ... as water below it. i have to identify both of...
the solid part is not ice one ,it may be built from stone,clays,bricks etc.,so what type of sensor we use to differentiate that. thanx. ... Get the freedom to...
hi guys. I've got some questions. on a proton magnetometer the homebuilt jobs use 2 spice bottles with spaced coils to read the proton precession rate. I would...
Stone, clay, brick, water and asphalt all have different dielectric constans. A capacitive sensor might be able to do the job. I don't know the particular...
Dear Friends, Kindly Download the whitepaper on the subject "Basics of Programmable Logic Controllers [PLC]". The whitepaper covers the following topics. 2....
My question is not directly related to sensors, it's more about wireless communication. I'm posting this question here, because you, guys, have seen a lot of...
