Saleng Tracker

The Saleng – Tracker module is a compact reflective infrared sensor module designed for detecting the presence or absence of an IR reflective surface (e.g. light or dark line) in front of its optical elements. The module uses the TCRT5000 IR pair while its output is fed to a Schmitt triggered gate producing reliable digital output. It has a Digital Output pin labeled DO and another with an inverted output signal labeled ~DO. DO is high when a reflective surface (e.g. white surface) comes within range and thereby reflecting back the emitter’s IR beam back to the IR receiver on the board. DO is low when no reflective surface (e.g. dark surface) is detected. ~DO’s output is the inverse of DO. The absence of a sensitivity/calibration adjustment potentiometer makes this module easy to use with its digital outputs optimized for dark/light line detection in robotic applications. An Analog Output pin named AO is also available and is tied to the output of the photo diode. This may be useful for distance or obstacle sensing. The tracker module is part of Layad Circuits’ Saleng series of innovation-starter products.

Ultrasonic UART Adapter

Using common ultrasonic sensors such as the popular HC-SR04 with a microcontroller maybe not that complex when used in simple applications. However, many real world projects will come with complexities of its own that makes the integration of ultrasonic sensors challenging. Traditionally, microcontrollers would have to poll on return signals of ultrasonic sensors to be able to calculate distance. This can be an issue in software as this receive sequence and actual transmission may be blocking algorithms. Using timer interrupts also incur processor time overhead and added reading error.
