Using Arduino Sensors
1

Hello,
I need IR sensor like this:

http://www.ebay.com/itm/IR-Infrared-Reflectance-Sensor-for-Arduino-Sensor-Shield-/140837269107?pt=LH_DefaultDomain_0&hash=item20ca8e2e73

with transmitter and emitter build in one and sensing distance minimum 1m.
Can anyone offer low-cost options?
Thanks.

do you have any tutorial how to build it or schematic?

4

google it diy ir sensor there about 750,000 examples

Try: Sharp GP2Y0A02YK0F Infrared Proximity Sensor detect 20-150cm Distance Sensor

verify using datasheet.

A search on digikey or mouser may also help:

Did you consider an Ultrasound or PIR sensor?
