// frequently asked

Q: Which sensor for ambient light measurement?I2C lux sensors are most accurate for room-light and display-backlight control. Analog photoresistors are simpler and cheaper for trigger/threshold use.

Q: Can I detect colors of small objects?RGB color sensors work for sorting beads, paint chips, or labels within a few cm. For finer detail, use a camera module instead.

Q: Will this ship from Manila?Yes — same-day 4 PM cutoff weekdays.

Q: What about UV sensors for outdoor weather stations?UV sensors output analog voltage proportional to UV index. Mount under a UV-transparent enclosure (most plastics block UV) for accurate readings.

Q: What's your return policy?7-day DOA window. Replacement or refund.

Q: Do you have wiring examples?Yes — forum.circuit.rocks has sample code for common sensors. Adafruit and Sparkfun product pages also publish wiring diagrams.
