An environment light sensor, also known as an eco-friendly photoresistor, is a device used to detect ambient light levels. It replaces traditional CdS photoresistors and complies with RoHS directives (lead-free and cadmium-free). This sensor is encapsulated with a specially designed light-filtering epoxy resin, providing spectral response characteristics similar to the human eye. It offers linear output with varying light intensity, certain temperature stability, low dark current, and low operating illuminance.
Key Features:
- RoHS Compliance: Lead-free and cadmium-free.
- Encapsulation: Special light-filtering epoxy resin.
- Spectral Response: Similar to the human eye.
- Output: Linear with changes in illuminance.
- Stability: Certain temperature stability.
- Current: Low dark current.
- Operating Illuminance: Low.
Applications:
- Light control circuits: For controlling and adjusting lights and background illumination.
- Consumer electronics: Televisions, PDAs, cameras, LCD/LED displays, and mobile phones.
- Toys and lighting control: Ensuring optimal lighting conditions.
The environment light sensor is highly sensitive to ambient light, making it ideal for detecting the brightness of surrounding light levels.
