Ms. What a wonderful "theatrical" presentation - your set is appropriate to your subject, your presentation skills, diction, eyes to the camera, voice quality - all excellent. Not to mention the information presented - clear, informative, good tips. I'm a new subscriber!
Looking to be an electrical engineer and I own an arduino (barely use it) but these videos are so helpful creating circuits will now become a full-time hobby
My advice if you are planning to take EE or EET.. focus more on actual circuits and not so much into coding.. arduino is an amazing tool but it's kinda cheating a tad bit lol
Same thing. I’m designing a fully automated garden running the PLC on a micrologix. I want to see if I can add an IR sensor to detect hail with a discrete output to control a motor connected to a sun shade or awing to cover the garden in a hail event.
I always b waiting for your videos this is very useful for us . I request to you please make a video on thyristor family like Diac Triac and SCR. How they work their uses and checking method.
Very informative! I have always seen those thumb print ridges on old sealed beam head lights and wondered what they were for. Now I know what they are called, thanks!
Question. Is it possible to use a PIR in a vehicle for detection of say, the bone density of passenger? The information would be used on airbag deployment. TIA.
@@pikakun6624 I have found out goes by body heat? if you wave a stick in over the pir sensor it will not go off. depends on what you need them for? I've made a few that go off with out the need for body heat. you can find them on my channel for ghost hunting
I have used PIR's to turn on my lights in the shop.. It has turned out to be real handy and I am glad I changed over. But I am more of a fan of the rcwl 0516 microwave sensor.. But that is another video..
We have occupancy sensors on our bathroom switches (installed with newly built home...) they use a PIR sensors to detect non-occupancy and turn the switch off after a time of no change in the sensor. The fun part about PIR near infrared is that it cant see through glass, so when in the shower it doesn't see the movement, just a uniform warmth. It was fun the first time we figured that one out....at 9PM.....while rinsing out shampoo..... So we have them set to maximum timeout (45min) effectively negating the benefit of the occupancy feature. Luckily we dont forget to hit the switch on the way out (out of compulsion), on the plus side the easy tap push button action makes doing so as simple as bumping the wall!
Thank you a lot for this video. I was wondering about the response times of this kind of sensors to detect movement and motionless; what are the orders of these response times? Are they same order? Do they depend on the 2 or 4 configurations (number of pyroelectric elements)? Thanks again!
It kinda depends on which sensor you're using. You should be able to find that information in the data sheet for each sensor. I've seen some that are very laggy and take a while to sense motion while others seem almost trigger happy and respond seemingly instantaneously.
I have RE200B. It requires an LM324 op amp and a thyristor. But the power cannot automatically be switched off! What more can I do to make a movement sensor?
HI, I will like to get some information ,application for High Mast tower , 20mtr tall/ 2500w . PIr or micro wave , which one works better. Also suggest the best brand.
