• Drive with logic HIGH at TTL level
• 2-mode operation: continuous drive or frequency drive
• Transmission range is 5 to 10 meters (line of sight)
Use the Inex Infrared LED Board in two different modes:
Continuous Drive: In this mode, the IR-LED will receive a forward bias to drive the infrared rays. Use with the for measuring the infrared light density.
Frequency Drive: Modulate the LED to a 38kHz carrier frequency using an external ciscuit such as a 555 timer IC or microcontroller. Use with the .
*Inex module pin-out: GND, SIG, V+
