Some circuits for Firefighting robots


Following are a number of circuits which I used to make my firefighting robot.  Most are commercially available circuits, but I include any signal/sensing characteristics I found while working with them.


Sharp IR range sensors:    Both the GP2D12 and GP2D15

Hamamatsu UVtron:   Ultraviolet candle flame detector

Eltek pyroelectric sensor:    Heat detector

White line sensors:   

Fan motor:       Motor and drive circuitry

Tone detector:    For Sound Activation mode
