fire detector

[kta22]

Hi people. Who can help me with a good fire-flame robotic sensor schematic ?I want to use this on my hexapod robot.
thanks

There are quite some different kind of fires and flames so what do you want to detect

have a google on flame detector as you have 2 different types

also heat sensors, smoke sensors and rate of rise sensors can be valauble for your project

be aware that if you have comercial ideas the devices have to be tested and certified before you can use them.

Give us more details on what exactly the sensor would be doing. Does it need to see a fire in the distance? Does it need to know if it is in a fire? Or would a smoke detection setup do the job?

The first thing I thought of was hooking up a smoke detector and temperature sensor to the robot. If either of those are present there is probably fire nearby.

You could also use infrared cameras, but the type of IR camera you would need is most likely prohibitively expensive.

hey i wouyld b glad if u could give me IC names of smoke sensros..

Hi,

Instead of using any particular IC, I would use the cheap electonic consisting of high brightness LED and a LDR place exactly face to face.

When their would be no interrruption between the LED and LDR, complete light falls on the LDR decreasing the resistance of the LDR.

When their would be any interruption (smoke) in the path this would led to less energy fall on LDR raising its resistance.

So you could detect the voltage change due to change in resistance.

here is my fire fighting robot

this is how we test robot

this is my robot at the competition.

we built two robots and both won first and second places.

NOTE: environment wasn't dark as it seems.cameraman was a fool who couldn't operate his own camera properly.i have to filter this video several times to bring it to viewable condition
