Gravity: Analog Ambient Light Sensor for Arduino (1~6000 Lux)

Here comes DFRobot's new Analog Ambient Light Sensor for Arduino or Raspberry Pi. Brand new design and much more convenient to use. This sensor help you to detect the light density and reflect the analog voltage signal back to Arduino controller. You can set the threshold of voltage level to trig other unit on Arduino project. 

We also use the enviromental PT550 light sensor and it is more sensitive to light than normal one. Place check following improvement we made. We always devote to bring better user experience.

To ease the difficult of using this light sensor,  a Gravity Interface is adapted to allow plug&play. The IO sensor shield is the best match for this sound senor connecting to your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry Pi, intel edison, joule and curie. 

1. Supply Voltage: 3.3V to 5V

2. Illumination range : 1 Lux to 6000 Lux

3. Responsive time : 15us

4. Interface: Analog

5. Size:22x30mm(0.87"x1.18")

Project 1. DFRobot AutoEco System takes care of your garden.
By following this project it will help to grow a vegetable garden, and automate some other processes in our house along the way.

Project 2. Micro:bit Surprise box
In this project it shows how the box interacts with flahsing hearts.

Project 3. Hyduino - Automated Hydroponics with an Arduino

hydroponics is growing plants without the use of a traditional dirt medium by using a nutrient rich water solution. This is especially great for those people that that have limited areas in their backyard to grow in.

Project 4: Environmental Monitoring System Based on OBLOQ-IoT Module
This product is mainly applied in electronic laboratory to monitor and control indicators such as temperature, humidity, light and dust, and timely upload them to the cloud data space to achieve remote monitoring and control of dehumidifier, air purifier, exhaust fan and dimmable light, etc. in the laboratory.     

Project 5: micro:bit Laser Target

The ambient light sensor sensor detects the intensity of the laser pointer. If it is greater than 400, it will sound the buzzer and the servo will make the target fall and up. Game over when it reaches 10. Press A to reset score to 0.

1. Wide voltage range from 3.3V to 5V

2. Standard assembling structure (two 3mm holes with multiple of 5cm(1.97") as interval)

3. Easily recognitive interfaces of sensors ("A" for analog and "D" for digital)

4. Icons to simplely illustrate sensor function 

5. High quality connector

6. Immersion gold surface
