Features of 5528 Photocell Photoresistor Sensor - 150V, 5mm0:

• Sensor Type: The 5528 is a photoresistor, which is a type of semiconductor that changes its resistance based on the amount of incident light. It is a passive component, meaning it does not require an external power supply.
• Operating Voltage: These sensors can handle voltages of up to 150V DC, making them compatible with a wide range of electronic circuits and applications.
• Sensor Diameter: The photoresistor's diameter is 5mm, making it small and suitable for various mounting configurations.
• Resistance in Darkness: In the absence of light or under low-light conditions, the resistance of the sensor is typically several megaohms, providing high impedance.
• Resistance in Bright Light: When exposed to bright light, the resistance of the photoresistor decreases significantly, typically dropping to several hundred ohms, resulting in low impedance.
• Response Time: The response time of the sensor, which indicates how quickly it reacts to changes in light intensity, varies by model but is generally in the range of milliseconds.
• Photoresistor sensors like the 5528 are commonly used in applications where light sensing is required, including:
• Light Sensing: Used in automatic lighting systems to detect ambient light levels and adjust illumination accordingly.
• Security Systems: Employed in security systems to detect intruders or motion by sensing changes in ambient light.
• Photography: Used in cameras for light metering and adjusting exposure settings.
• Energy Conservation: Integrated into devices to optimize energy usage by controlling lighting and displays based on ambient light.
