- Standard assembling structure (two 3mm holes with multiple of 5cm(1.97″) as interval)
- High quality connector
- Immersion gold surface
- Supply Voltage: 3.3V to 5V
- Illumination range : 1 Lux to 6000 Lux
- Responsive time : 15us
- Interface: Analog
How does it work?
A photodiode generates a current when light hits the body of the diode. It can be thought of as the opposite of an LED where light is generated when a current is present. Sometimes it is also called a photo-detector, a light detector, or a photo-sensor.
