Gravity: Analog Ambient Light Sensor For Arduino

DFRobot presents a brand - new Analog Ambient Light Sensor designed for Arduino and Raspberry Pi. With its innovative design, it offers unparalleled convenience. This sensor can precisely detect light density and send an analog voltage signal back to the Arduino controller. You can set a voltage threshold to trigger other components in your Arduino project. We've employed the environmental PT550 light sensor, which is far more light - sensitive than ordinary sensors. We're committed to enhancing your user experience. This Arduino light sensor is extremely sensitive and can capture the slightest light changes! To simplify its use, we've integrated a Gravity Interface for plug - and - play functionality. The IO sensor shield is a perfect match for connecting this sensor to your Arduino. It operates at 3.3V, making it compatible with Raspberry Pi, Intel Edison, Joule, and Curie. SPECIFICATION: Supply Voltage ranges from 3.3V to 5V, Illumination range is from 1 Lux to 6000 Lux, Responsive time is 15us, Interface is Analog, and Size is 22x30mm (0.87'x1.18'). DOCUMENTS: Wiki (DFRobot Ambient Light Sensor), Schematic, PT550 Datasheet. SHIPPING LIST: One Analog Ambient Light Sensor and one Analog cable. IMPROVEMENT LIST: Wide voltage range (3.3V - 5V), Standard assembling structure with two 3mm holes at a 5cm (1.97') interval, Easily recognizable sensor interfaces ('A' for analog and 'D' for digital), Icons for simple sensor function illustration, High - quality connector, Immersion gold surface.

Using this light sensor is a breeze. First, connect it to your Arduino or Raspberry Pi using the provided analog cable and the Gravity Interface for plug - and - play. If you're using an Arduino, the IO sensor shield is a great match. Set the voltage threshold according to your project needs to trigger other components. When it comes to placement, keep in mind that the PT550 light sensor is highly sensitive, so place it where it can accurately detect the light you want to measure. For maintenance, avoid exposing the sensor to extreme temperatures or humidity. Clean it gently with a soft, dry cloth if it gets dirty. Always make sure the power supply is within the 3.3V - 5V range to keep it working properly.
