Low cost Infra Red Transmitter & Receiver

Infra Red Transmitter is a sender module data via infrared waves that come with a carrier wave generator with a frequency of 38 kHz. This module can be used as a transmitter for wireless transmission of data in applications such as robotics, security systems, datalogger, etc..


specifications:

  • Working voltage: +5 VDC.
  • Carrier frequency of 38 kHz (can be matched using a variable resistor).
  • Wavelength: 940 nm (peak).
  • Beam angle: +17 degree.
  • The maximum distance of 16 m (tested at an angle of 0 degrees) and 35m (according to the datasheet).
  • Has an input voltage levels are compatible with TTL, CMOS, and RS-232.
  • There are 2 modes of output: non-inverting and inverting.


Infra Red Receiver is a receiver module data via infrared waves with a frequency of 38 kHz carrier. This module can be used as a receiver for the wireless transmission of data in applications such as robotics, security systems, datalogger, absenteeism, etc..


specifications:

Working voltage: +5 VDC.
38 kHz carrier frequency receiver.
Relative sensitivity peak occurs at a wavelength of 940 nm.
Acceptance angle: +45 degree.
Has 2 outputs (inverting and non-inverting) voltage levels are compatible with TTL, CMOS, and RS-232.
Dimensions: 3.4 cm (P) x 2.5 cm (L) x 1.4 cm
