guys about lights and fan controller with human counter

[yeoj_lost]

ahm..pde po pahelp...pano ung logic n2? kasi di q alam kung pano ..ang naisip q po..ung sensor is connected din dapat s lights and fan, pero panu po ito? do we need to use a computer para mging medium para macontrol ung fan and lights.? and anung sensor po kaya ung gagamitin.? ir sensor din ba?

any suggestions will help po..about sensor and kung pano po gagana ito .ipopropose q ka and i dnt know yet qng panu un.. sana may makatulong ..tnx

[insomartin]

inuubo ka sir? kindly limit the use of "ahm..." it's awkward kasi, limit natin okie?

may PIR sensors para sa detection nang large moving objects such as TAO...
for computer pwede na ung MCU or PIC or ZILOG or Arduino. or PC whatever youlike basta open ka magexplore / magaaral nang programming
then ung lights and fan relays lang yun sir.

medyo mahirap pero unti unti mafifigure out mo naman sir!

[yeoj_lost]

thank you po..sori s "ahm"

anu po ung P s PIR.. ?
meaning po.. pde gwin alternative sa PC etong mga MCU or PIC or ZILOG or Arduino

tpos, parang gnito ung pagkakasunud-sunod?
PIR sensors >> MCU / PIC/ ZILOG /Arduino >> RELAY >> gnun po b?

[insomartin]

ayun naman pala eh! gets mo na. hehe i concur po! gnun nga! 
antay mo lang.. wait

[yeoj_lost]

sir.. can i ask again.. kasi nga nakuha q lng ung idea n 2 s isang post din kay rj ata un ng tagaytay, san po kaya q mkakabili ng 2 sensors n cheap pero magagamit nmn ng maayos gaya din ng microcontroller n ggmitin q..

sir..gusto ko lng i confirm if ung relay dba..connected sya s lights/fan pra ma on/off sya..then ung relay nmn ,ang parang mag aactivate nun e ung prinogram s microcontroller, tpos maactivate un dahil s sensor? hehe sensya po kung makulit..hehe baka magkamali kc , ipopropese ko plng sya..

posible po kya n isang microcontroller lng ang gmitin para s 2 purpose like ,ung pag may dumaan s sensor and confrmed sya as "TAO" tpos send it to microcontroller then s relay nmn para ma on ung fan..?

2 duties po ung ggwin ng microcontroller? or nid tlga ng dalawa..
thank you po

[insomartin]

ayan ah! ginawan pa kita nang actual working device! san ka pa! 

[yeoj_lost]

haha sir , i really appreciate it..haha sumasakit n ulo q kanina pa .nabasa q mga post niu last june 13 pa un eh? so ngwan nio pla ng paraan ung human counter , pde po malaman qng ngkita-kita p kau? or kaw lng gumawa? astig nmn ..

just want to ask sir kasi working n yan, kita q nmn s image that uve sent. Sir mgkano po ung gastos jan? nahirapan po b kau paganahin ? wat programming languages po ginamit nio ? mix po ba of two PL? im just curious , kc laking tulong din 2 s school q and school n pinagttrabahuhan ng mama q  if ever nkagawa din aq ng tulad nian.. tnx po

[insomartin]

medyo may kamahalan yung pir...

here's a very rough cost...
PIR cost 580
the uC PIC cost 180 pesos
relay is 60 each you'll need only one.

so medyo mahal...

flowcode 4 gamit ko... download ka nang trial sa matrixmultimedia.com
and JDM programmer. dalawang resistor lang at via serial port.
okie!?

[yeoj_lost]

d nga po? u mean d p lumagpas ng 1000php ung lahat ng ginamit?
sir.. kaw lng mag isa gumawa ? i mean ,, oo tama kaw lng po? ..ilang days nio po nagawa yan? just curious..ang gling kc

[yeoj_lost]

sir..may update po b kau s project ni rjp? sya po ung ngstart ng topic dba? nung june pa for his thesis, i wonder if nagawa n nia? nbasa q s mga post nia na nhihirapan sya bout s mga sensor .. natapos nia kaya? kasi kau po ntpos nio n dba

[insomartin]

module yung PIR sa e-gizmo.com
pati parts sa kanila din.

nangyari kasi sa thread is andaming marunong na na flood na yung tread. walang nasimulan, at hindi natapos. hayst ... iniwan ko na yung thread knowing neverending assumption nang ibang members. may sa mythbuster, may computer vision.... bahala sila. eh bakit ang MRT araw araw nila ginagamit yung card at yung stainless na rotating human counter nila? diba?

[yeoj_lost]

oo nga po.. andami din plang pdeng gmitin para mgka human counter.haha ngkagulo sila..tntgnan q po qng natpos n rjp..

d po ba, ung pir sensor..sa pinto un ikakabit para pagdaan ng tao..aun madedetect ung body heat ng tao, tpos mag oon ung lights/fan..dpat din po pag ng 0 ung tao s rum..mag o off..

panu po ung logic ng natpos nio n project? same as the logic lng b ng proposed thesis ni rjp ? ..kasi nabasa q po..he used 2 kinds of sensor ata..s pinto..and i saw sa image po n pinadala nio na isa lng ung sensor.. san po un ilalagay? may area po b n nasasakupan kung hanggang san lng ang kayang idetect nito s loob ng rum? im not very familiar po kc with sensors? ..
sori po..and thanks

[insomartin]

you'll have to keep on MOVING for the PIR na mag Logic HIGH (ON STATE)

yung mcu mag titime nang kung ano una nya i ooff...

like after nya hindi makadetect sa PIR
una muna magooff yung FANS
then after siguro 10 minutes LIGHTS naman magooff.

so you have to keep on moving... parang screen saver kapag di mo ginalaw yung keyboard or mouse mag oon sya.

[yeoj_lost]

ah gets haha sir prang my nbasa ko n gnyan..n post na  "wag nmn sna mtulog ung mga tao n parang patay ? " ..sbgay sir magalaw nmn s loob ng rum even my discussion and my exam.. db?

so it depends po s program nmn kung kelan nmn gusto mg turn off ung fans and light.. gnun din po b sa inyo?

thanks po..sna maaprove 2 as a proposal..
sir ..sana po if maaprove and may katanungan aq ..anjan po kau Godbless..

kung lalagyan ng counter variable sa code, pag me pumasok na tao = accumulate ang variable(hindi na siya ZERO), then pwede na start ang electric fan,

pag me pumasok ulit magiging "2" na ang value ng variable, so hindi siya ZERO kaya di pa rin i-ooff ang fan.

pag me lumabas, magsusubtract ng kung ilang tao ang lumabas, hanggang maging ZERO ang variable then yun na, io-off na yung FAN then wait for 10minutes para i-off ang LIGHTS.

problem lang pag sabay lumabas ang 2-tao, baka ma-count as "1" lang...

[yeoj_lost]

panu kua yng cnsbi mo? ung counter variable n yan? kse..ung motion sensor po..kahit may tao p siguro s loob ng rum e kung d nmn gumagalaw e ma ooff tlga ung fan dba? sb ni sir martin. dapat continous ang movement hehe

[insomartin]

ang ginawa ko lang kasi is motion sensor with custom timer... air con naman para high end...

pseudo code...

if heat detected
run timer
run relay of air con
run relay of lights
if 10 minutes already
stop relay of air con
if 20 minutes already
stop relay of lights
back to start
___end_____

so pwede din lagyan nang interupt sa doors as per sir macky said. na may switch sa doors / or counter na magcocount nang tao.

[silent_halfdEad]

pwd po ba malaman details ng motion sensor mu?

[yeoj_lost]

sir martin,possible din po ba ? na gmtin ang PIR motion sensor.. at ung concept mismo ng lights and fan controller sa motion sensor mo po with custom timer?

can u give me more example po n pdeng pag gmitan ng PIR like ligts/fan controller, ung maiaaply ko po ung concept nia on other things beside lights and fan?

[insomartin]

typical application kasi nang pir is for security systems. kapag nakadetect nang tao magaalarm.

one is safety features din on the other hand for restricted hazardous areas or hospitals corridors para makasave nang electricity.

as far as that di ko alam kung saang applicable pa ang pir.
