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
