Frequently asked questions
What is the price of LDR Photo Resistor Sensor 5mm Model 5537 in Egypt?
LDR Photo Resistor Sensor 5mm Model 5537 currently costs 5 EGP in Egypt.
Where can I buy LDR Photo Resistor Sensor 5mm Model 5537 in Egypt?
LDR Photo Resistor Sensor 5mm Model 5537 is available from Microohm. Compare the offers above to find the best price.
How do I read it with a microcontroller?
Build a voltage divider with the LDR and a fixed resistor, then read the midpoint on an ADC pin. The fixed resistor value sets the sensitivity range, so choose it according to the light levels you need to detect.
Is it suitable for measuring light accurately?
No. LDRs respond slowly and non-linearly to light, so they are better for detecting changes or threshold levels than for precise light measurement.
