// frequently asked

Q: Which sensor should I pick for a beginner project?Start with a digital 1-Wire or I2C sensor — simpler wiring, no analog calibration needed. Check the product description for typical accuracy and range.

Q: Do these work outdoors?Some yes. Check the product page for IP rating or weatherproof variants. Bare-board sensors need an enclosure for outdoor use.

Q: Will this ship from Manila?Yes — same-day cutoff 4 PM weekdays via J&T or LBC.

Q: Where do I find wiring guides?Most sensors have sample code linked on the product page or on our forum at forum.circuit.rocks. Adafruit and SparkFun also publish detailed datasheets.

Q: What's your return policy?7-day window for DOA. Replacement or refund. Used parts not returnable unless faulty.

Q: Do you offer technical support?Yes — forum, email, or message us. Weekday and weekend support.
