Sharp IR Distance Sensor

[dguimaraes]

Hi,
I'm using Sharp Distance Sensor (20-150cm) with IR Distance Adapter.
If I declare the sensor type:

PhidgetVoltageRatioInput_setSensorType(voltageRatioInput0, SENSOR_TYPE_1101_SHARP_2Y0A02);

After this I never receive reads... I only can use this setup receiving values from voltageRatio value... how can i receive data in distance like mm

thanks

If you open it in voltage ratio mode, what range of values are you getting?

The formula for converting voltage ratio to distance is:

Distance (cm) = 9.462 \ (VoltageRatio - 0.01692)

This formula is only valid for VoltageRatio between 0.08 and 0.49.
