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 with the
RCX I'd be grateful if they could e-mail me about it.
I think it could sense the ultra-voilet or infra-red light coming off the
flame. It would have to be very responsive and fast at reacting. Also, it
would only have to be able to see the flame from a foot away max. Once again
if anyone has heard of something that could do this, I'd be grateful if they
could contact me ASAP.

| 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)
