Sensors

For our robotics project we plan to use CN 70 sensors but we need a circuit that increases the voltage taken from the sensor. Is there any addresses we can find such circuit diagrams?
Can you suggest any sites that gives info about different type and brand
sensors?

I am not sure what the CN70 sensor is like, is it a infrared sensor? A google search didn't give me anything. :shock:

There are distance sensors made by SHARP. Like the GP2D120 and a whole bunch more. Check out acroname for more examples

Thanks. We will have a look at it.
