How do I read this LDR with an Arduino?
Build a voltage divider: connect the LDR between 5V and an analog pin, and a fixed resistor between that pin and GND. Use a fixed resistor in the same order of magnitude as the LDR (for example around 47kΩ) and read the pin with analogRead().
Is it suitable for precise light measurement?
No. Photoresistors respond non-linearly and slowly, so they suit light detection and relative brightness control rather than calibrated light measurement.
