Kimat – LDR Module
Overview
The Kimat – LDR module is a simplified light sensor
module with analog output voltage. It uses a light
dependent resistor as sensing element. A user
adjustable potentiometer is provided for sensitivity
adjustment and possibly for simulation of a digital
output. The module includes a power indicator LED and
breadboard- friendly pin headers. The Kimat – LDR is
part of Layad Circuits’ Kimat series of rapid prototyping
products.
Application:
The Kimat-LDR module converts light falling on its light
sensitive element into a voltage that varies somewhere
between ground and Vcc. This is meant to be hooked up
to an ADC input of a microcontroller or a dedicated ADC
circuit. The output is uncalibrated and non-linear, hence
testing with actual lighting conditions is recommended.
This humble module has several applications. It may be
used as an ambient light sensor or when coupled with
directional light source such as lasers, may be used as
beam-cut sensor for object/people detection or even as
a speed meter.
