Hi everyone,
Imagine you've got a proximity sensor, say a
capacitive, DC, 3-wired one which should sense
a passing object in the range 10/20mm. It has
voltage drop at max load <3.5V and max rated load
250mA. The object is passing approximately at a
rate of 60 times a minute that is 1Hz, largely
under the sensor performance.
The sensor should than be connected to the
joystick port of a PC so that when it switches,
it simulates the fire button.
What kind of circuitry between the sensor and the
PC joystick port should be added to make it work
mantaining the TTL levels, supposing that the
sensor is supplied with 24VDC?
Is there any better solution than the joystick port to interface PC and proximity sensor
(parallel port not available)?
Thanks a lot.
Stefano
