Description: A Light Dependent Resistor (Abbreviated LDR) or Photoresistor is a passive electronic component that changes its resistance in response to varying light intensities. It exhibits photoconductivity, meaning its resistance decreases as the light intensity increases. Photo-conductive Material in this LDR:Cadmium Sulphide (CdS): sensitive to visible light, used in many applications LDRs are used in various applications, including:Light detection and indicationLight intensity measurement (with limitations due to temperature and time latency effects)Flame detectionProximity sensingAutomation and control systemsThe key thing to note about LDR's are that the amount of light entering them is inversely proportional to the Resistance of the sensor. Specs:Type: GL5539 Max. power consumption (@ standard temp. 25 degrees Celsius): 100 mWEnvironmental temp.: -30 ~ 70 degrees CelsiusSpectrum peak value: 540 nmLight Resistance (@ 10 Lux): about 5 - 200 KΩ (lower and upper value's are theoretical)Dark Resistance: 0.5 - 10 MΩ Response Time: Decrease (-) or Increase (+) of 30 milliseconds Best Practices: Avoid high temperature and humidity for storing.Soldering should be completed in the shortest possible time.It is recommended that the soldering should keep 4 mm away from ceramic substrate (The base material underneath the sensor). Item is in qty of 20 photoresistors. Will ship same or next day via USPS Ground shipping. Feel free to reach out for questions.
