Infra-Red Temperature sensors
Archiver
Posts: 46,084
I am developing race car telemetry systems, and am being pestered
by a potential customer to give him the facility to monitor tyre
temperatures whilst his race cars are on the circuit.
We would like to monitor all 4 tyres, and the inner, middle and outer edges
of each tyre.
Infra red sensors I presume are my only viable non-contacting option, but
here in the UK the cheapest
I can get them is about ?150 each - or ?70 if I dismantle some cheap
handheld temp guns!
Anyone know of a source of good quality sensors at a much lower cost than
this?
?840 for the sensors (I'll need 12) makes it a non-starter.
Also, are they fairly straightforward to read from - eg variable duty cycle
pulses or something?
Thanks for any help
