The Pololu QTRX-HD-13RC Reflectance Sensor Array: 13-Channel, 4mm Pitch, RC Output, Low Current is an advanced sensor array designed for precise detection of reflectance changes, such as those encountered in line detection applications. This array consists of infrared LED and phototransistor pairs, which are capable of detecting high-reflectance objects at distances up to approximately 40 mm. The device operates efficiently within a voltage range of 2.9 V to 5 V, and it features dimmable brightness control that functions independently of the supply voltage. Additionally, it offers separate control for odd and even emitters, enhancing its versatility in various applications.
The sensor array is equipped with high-performance, low-current QTRX sensors that include lenses, optimizing its performance while maintaining low power consumption. The output is compatible with digital I/O signals, which can be read in parallel as timed high pulses, facilitating integration with various systems. The optimal sensing distance for this array is around 10 mm, making it suitable for applications requiring close-range detection. The compact design, weighing only 3.1 grams, ensures that it can be easily incorporated into a wide range of projects without adding significant weight or bulk.
If you are not satisfied for whatever reason with a Product you bought on the Site, it is possible to return it for refund within 30 days from the date you received it unless otherwise indicated in the Product listing.

The Product must then be returned in its original packaging (in perfect condition for resale) with its receipt and your (‘’RA’’) number. Reimbursement will be denied for any Products which do not conform to the above mentioned conditions.
Build-it-yourself Robot Parts are not refundable once assembled. Robots & Kits requiring assembly or soldering are also not refundable once assembled, soldered or modified in any way. All sales of robotic software and apps are final and cannot be refunded or exchanged. Returns are not accepted on special orders and clearance items except when they are found defective, in which case the Product may be repaired or replaced at the Vendor’s discretion. 20% Restocking fees may apply if you are returning a large quantity of the same Product that was ordered specifically for you from the manufacturer.
Please note that all items will be reimbursed within 7 to 14 days of receiving the Product (shipping fees excluded). You must also cover the cost of returning the Product. Shipping fees will only be refunded if the return is a result of a shipping error on our part. Cleaning fees of USD 100 may also be charged if a domestic robot is returned and has not been properly cleaned.
