hello, reference this could works fine only if your PIC input is trigger type ... because of slow rampe of voltage Software filterring is maybe a better solution.. Other advises ? I a taking the input from infrared sensor [ATTACH=C
hi actually i am doing a project in which when an obstacle comes in between infra red rays it should activate a micro controller. the micro controller in turn activates a video camera and a gsm module. the camera takes a video for 10 seconds and the gsm module needs to send this 10 sec video clip to 3 mobile numbers. this is my project for this i w
can I use a 940nm infrared led detector with the 850nm and 880nm emitter infrared led ?
Photovoltaic panels turn light into electricity. The panel gets hot just sitting in the sun. It will heat up a little more than usual if you draw several Amperes from it. However that portion of heating is minor compared to the infra-red portion of sunlight. If you could shine pure visible light on the panel, I suppose any temperature (...)
Also, PIR type sensors they donīt produce fast enough response. Are you talking about a light that turns on when something moves in front of it? I was going to suggest this. Some (or all) work by infra-red. The ones I've seen have a translucent lens over the sensor. The lens is multi-faceted. A moving object produces
This all sounds very answer to your questions is
Do you mean the peak power of the infra red? Measure the power going into the diode, look up the manufacturers spec. Compensate for any focussing optics and you have your answer. Frank
The purpose is to open or close a faucet by the application of a stepper motor. The stepper motor will work by receiving signals from a PIC16F877A microntroller. This microntroller will be connected to a heat sensor. Most probabbly a IR detector. So i have outlined the code below. However, the code isnt working. And i am unable to debug. A
I see a Wireless Tachometer. Also an infra-red Tachometer. Both on Ebay. What 'pickup' do they have? I thought I'd make one, if it's not too complex. Thanks for any advice (other than buying one) that I may use.
What is "any infra-red signal"? You forgot to mention it.
Hello, What is the emissivity of the surface of this ferrite? MSD1583 sepic inductor: .....I need to know in order to set the emissivity on the infra red camera.
Hello Which end of the "thermohawk 400u" houses the sensor?....(I hope its the small end as I wish to measure temperature of very small electronic components)
Hello, Please can you evaluate this method of ensuring that the reading of infra red temperature monitors is correct? (it relates to accurately reading the temperature of components in an smps). infrared thermometer: When testing an SMPS, it is essential to do thermal tes
i want to make wireless IR sensor using 8051 and zigbee can any one help me in circuit and coding ,, i am going to develop an parking slot detector using IR sensors for this project i decide to use 8051 ,zigbee , . there is an zigbee connected with computer which is used to get status of other sensors and than computer will updat
usually ultrasonic sensors are used for this purpose , but i guess infra red can be used too . check this sample code an di helps it would help
They look very much like the infra red photo diode you see in some mice, except they have a clear case and the infra red ones are black. I think that they are definitely photo diodes though.
Hello I though this is not a photo transistor, may be this is an infra red receiver. But why don't you check it just like a transistor?
I think you will use the 555 as Pulse Width Modulator and put modulation into pin 5 of the 555, and yes you could do it with small fm tx/rx or maybe infra red or any analog transmitter from any audio source..just have to couple pin 5 and some level adjustment
Hello sir i want to know about the effect of infra red rays over house flies mosquito etc etc Are they come close to that or try to leave the area of effect ?
Hi Greetings, I have some questions. I found a Nice infra red object detection project on a wesite link i tested it out and its working fine but i am facing some difficulty when i try to make it work with a pic18f2550 microcontroller. I
