TCS34725 RGB Colour Sensor Module with IR Filter & 4150K LED I²C

🌈 TCS34725 RGB Colour Sensor Module with IR Filter & 4150K LED | I²C | AuscomTech

The TCS34725 RGB Colour Sensor Module is a high-accuracy digital colour sensing board designed for precise red, green, blue (RGB) and clear light measurement in embedded and microcontroller projects.
Based on the AMS TCS34725 colour sensor IC, this module integrates an infrared (IR) blocking filter and an onboard neutral-white illumination LED (~4150K) to deliver consistent, repeatable colour readings even under changing ambient light conditions.

With a wide dynamic range, high sensitivity, and simple I²C interface, the TCS34725 is ideal for colour detection, light measurement, calibration systems, robotics, and IoT applications.

⭐ Key Features

Australian Stock – Fast Dispatch

All items are held in stock right here in Queensland, Australia. We do not use overseas drop-shipping or third-party dispatch — every order is packed and shipped directly from our Tingalpa facility.

Most orders are dispatched same business day if placed before our cut-off times, or next business day if purchased after hours, on weekends, or public holidays. Unlike some sellers who only pack orders every few days, we dispatch daily (Mon–Fri) to ensure you receive your order as quickly as possible.

We’re also constantly expanding our range and product offering. If you can’t find a specific item in our listings, please reach out to us — we can often source or order it in through our supplier network and add it to our store for you.

Product Variations

With most electronics, manufacturers make design changes that can occur as frequently as each production batch. This means components used, PCB colours, and even pin positions or connections may differ slightly from the images shown.

The images in our listings are for reference only, and all products supplied meet or exceed the stated specifications.

If you have something specific that you require — such as a particular layout, chip version, or pin configuration — please confirm with us prior to ordering.

 

Payment

All payments are handled securely through eBay Managed Payments. We don’t accept payment on pickup — please complete checkout on eBay before collection.

  • Credit & debit cards (Visa, Mastercard, American Express)
  • PayPal / PayPal Credit
  • Apple Pay & Google Pay (supported devices)
  • Afterpay (where available)
  • eBay Gift Cards & vouchers

Once payment is received, eBay notifies us automatically and your order is queued for dispatch.

Service & Warranty

We’re committed to great service and genuine local support. If you have any questions before or after purchase, please contact us via eBay Messages.

All products include a 12-month warranty (unless otherwise stated) covering manufacturing faults and component defects only. Not covered: misuse, incorrect wiring, reverse polarity, over-voltage, modification, physical damage, exposure to moisture, or other improper handling.

If you experience a problem

  • Contact us first before opening a return or case — most issues are resolved quickly with simple troubleshooting.
  • We may request details or photos to identify whether it’s a warranty fault or a setup issue.
  • Items returned that test as “no fault found” or are damaged through misuse may be returned to the buyer at their cost.

Returns

Hassle-free 30-day returns. If you change your mind or need to send something back, we’ve got you covered. Items must be unused and in original condition with all accessories.

How to return

  • Fast & Free (Untracked letter): Use the original envelope. Neatly cross out your name/address, write “RETURN TO SENDER” on the front, and drop it in any red Australia Post street box. Then send us a quick eBay message with your order number so we can watch for it.
  • Tracked parcels (Standard / Express): We’ll issue a pre-paid return label (Australia Post). Print & lodge, or use the provided QR code at the counter if available.

Faulty or DOA?

Please contact us first. We’ll troubleshoot quickly and, where a warranty fault is confirmed, we’ll arrange a pre-paid return or direct replacement under our 12-month warranty.
