LDR Analogue Linearization Circuit for a Bubble Light Tracking
Authors: , ,
Abstract: Light dependant resistors (LDR) are widely used in robotic world to detect or avoid obstacles or to measure light level in home automation system. Such commercial sensors have a non linear response curve. This paper presents a simple and clever analogue COTS circuit to obtain a linear response. Theoretical design is explained; simulation and measurement results are commented. An example of application is given for a small scale solar tracking system with two LDR sensors.
