LTR-301 Infra Red Receivers
Now available from PMD Way are these compact side-looking infrared receivers.
These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing.
Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.
Use the options menu to select the pack size. You can also select a pack that contains fifty pairs or LTR-301 receivers and LTE-302 transmitters.
