Hi ,
Thanks a Lot, indeed it was a great help , It has imporved my thought Process.

Goals are :
1. Zero Speed Measurement
2. Accuracy 1% of the Velcoity Travelled
3. Fucntions in extreme environmental conditions
4. Cost-Effective [ <500$ ,but subjected to change if necessary]
[note : Vehicle is extensively used on Lawns ]

The Activity we are currently involved is to choose a sensors that would best suite our purspose.


I did check out some optical sensors , they seem to be pretty costly [ Corrsys-Datron]
Any manufacturers where I can get Optic Sensors.

I would also like to know manufactures for Hall Speed Sensors and Radar Speed Sensors too .[ during the Study phase of the sensors I could a list a few but it would be great , If I could add on to my list ]

1. During the process of Studying about the Speed Sensors I could find
Gear Tooth Speed Sensor , Transmission Speed Sensors. can these sensors be used to find the Wheel Speed / Vehicle speed
2. Is there any difference between Gear Tooth Speed Sensors and Wheel Speed Sensors .Will the Gear Tooth Speed sensors be helpful to Find the Speed of the Vehicle.



Thanks & Regards
