I am trying to build a sensor to attach to the RCX that can sense a candle flame. I'll be attaching it to a robot that will use it to look for a candle, go to it and extinguish it. If any one has heard of such a sensor that's able to be interfaced (...) (22 years ago, 22-Dec-02, to lugnet.robotics)

Just a quick thought, I was thinking that using both the light and temperature sensors might be the way to go. Let the robot search or seek the brightness of the flame with the light sensor. Then if the value is true, measure the heat with the temp (...) (22 years ago, 22-Dec-02, to lugnet.robotics)

(...) Lego actually make an 'official' temperature sensor. I guess that in combination with the light sensor, you'd be able to detect a candle flame. The biggest problem may be how to get the temp sensor close enough to the flame to unambiguously (...) (22 years ago, 23-Dec-02, to lugnet.robotics)

I know that the terms of use for lugnet prohibits advertising, but I assume it permits anti-advertising :) The item identified in this post will not act as a flame sensor. It is a proximity sensor which works by emitting its own IR illumination (...) (22 years ago, 23-Dec-02, to lugnet.robotics)
