Photoresistor (LDR) how

  1. Photoresistor what changed in resistance value depending on the ambient light, I often read the message. Lighting if the resistance value. Let us read what if I started resistance value.

  2. The first is a photoresistor. I think it could have been called LDR (Light Dependent Resistor). An error also available.

  3. Photoresistor (or) LDR DMM to measure the resistance value depending on the lighting conditions we received.

  4. The second image is a normal day at 2 under fluorescent lighting Photoresistor (or) LDR's Resistance value has a value of 12.4 K ohm.

  5. The third picture Photoresistor (or light) LDR paper roll width without the DMM to measure resistance value of 136 K ohm.

  6. Photoresistor (or) LDR in the paper roll width and SmartPhone through lighting and DMM to measure the resistance value of 1.8 K ohm.

  7. Photoresistor (or) LDR Black Cover Resistance measured value to the DMM has a value of 0.5 M ohm.

  8. According to the above measurement Result Resistance value if light gets low. Or less, based on received light can learn how different resistance values.

  9. According to Ohm Law to go Resistance value Voltage value will change. About street lights and the opening / closing Idea for your Idea above.

Photoresistor ( LDR ) ဘယ္လို အလုပ္လုပ္သလဲ

၁။ Photoresistor ဟာ အလင္းေရာင္ ရရွိမႈေပၚမူတည္ၿပီးေတာ့ resistance တန္ဖိုး ေျပာင္းလဲသြားတယ္ ဆိုတာကုိ စာထဲမွာ ခဏခဏ ဖတ္ခဲ့ရဖူးပါတယ္။ အလင္းေရာင္ ရရင္ resistance တန္ဖိုး က်သြားပါတယ္။ ေမွာင္လာရင္ resistance တန္ဖိုး တက္လာတယ္ဆိုတာကုိ ဖတ္ဖူးၾကပါတယ္။

၂။ ပထမ ပုံကေတာ့ photoresistor ျဖစ္ပါတယ္။ LDR (Light Dependent Resistor) လို႔လည္း ေခၚဆိုႏိုင္မယ္ ထင္ပါတယ္။ မွားယြင္းမႈလည္း ရွိႏိုင္ပါတယ္။

၃။ Photoresistor (သုိ႔မဟုတ္) LDR ကုိ DMM နဲ႔ Resistance တန္ဖိုးကုိ အလင္းေရာင္ ရရွိတဲ့ အေျခအေနေတြေပၚ မူတည္ၿပီးေတာ့ တိုင္းတာႏိုင္ၾကပါတယ္။

၄။ ဒုတိယပုံမွာ သာမန္ ေန႔အခ်ိန္ ၂ ေပ မီးေခ်ာင္း အလင္းေရာင္ေအာက္မွာ ရွိတဲ့ Photoresistor (သုိ႔မဟုတ္) LDR ရဲ႕ Resistance တန္ဖိုးဟာ 12.4 K ohm တန္ဖိုး ရွိပါတယ္။

၅။ တတိယပုံမွာ အဆိုပါ Photoresistor (သုိ႔မဟုတ္) LDR ကုိ စကၠဴလိပ္အတြင္းထည္းၿပီး အလင္းေရာင္ မေပးပဲ တိုင္းတာၾကည့္တာ DMM မွာ Resistance တန္ဖိုး 136 K ohm ရွိပါတယ္။

၆။ Photoresistor (သုိ႔မဟုတ္) LDR ကုိ စကၠဴလိပ္အတြင္းထည္းၿပီး SmartPhone ကေနတဆင့္ အလင္းေရာင္ ေပးၿပီး တိုင္းတာၾကည့္တာ DMM မွာ Resistance တန္ဖိုး 1.8 K ohm ရွိပါတယ္။

၇။ Photoresistor (သုိ႔မဟုတ္) LDR ကုိ အမဲေရာင္ Cover နဲ႔ အုပ္ၿပီးေတာ့ Resistance တန္ဖိုး တိုင္းတာၾကည့္ရာမွာ DMM မွာ 0.5 M ohm တန္ဖိုးရွိပါတယ္။

၈။ အထက္ပါ တိုင္းတာတဲ့ Result ေတြ အရ အလင္းေရာင္ ရရင္ Resistance တန္ဖိုး နည္းလာပါမယ္။ အလင္းေရာင္ အနည္း အမ်ား ရရွိတဲ့ အေပၚမူတည္ၿပီးေတာ့ resistance တန္ဖိုးလည္း ကြဲျပားသြားတာကုိ ေလ့လာႏိုင္ပါတယ္။

၉။ Ohm Law အရ Resistance တန္ဖိုး ေျပာင္းသြားရင္ Voltage တန္ဖိုးလည္း ေျပာင္းသြားမွာပဲ ျဖစ္ပါတယ္ ။ လမ္းမီးနဲ႔ ပတ္သက္ၿပီး အဖြင့္ / အပိတ္ လုပ္ေပးတဲ့ Idea ကလည္း အထက္ပါ Idea ပဲ ျဖစ္ပါတယ္။

ေက်းဇူးတင္ပါတယ္
