Infrared Alarm: This circuits consist of two parts, the first part will
transmit a signal, and the second part will detect that signal and trigger a relay.To
adjust the circuit, hold down S1 while pointing LED1 at the receiver. Adjust R6 until
you hear the relay. You can increase range by using a high output LED for LED1. Bright
light will stop the receiver from responding to the transmitter. (added 3/03) |

Infrared Head Phones: Using this low-cost project one can reproduce audio
from TV without disturbing others. It does not use any wire connection between TV and
headphones. In place of a pair of wires, it uses invisible infrared light to transmit
audio signals from TV to headphones. Without using any lens, a range of up to 6 metres
is possible. Range can be extended ..... (added 4/02) |

IR distance ranger covers 1 to 20 cm: 04/11/02 EDN Design Ideas /
(added 1/05) Commercially available IR distance rangers typically handle a 3to
30-in. detection distance. Many times, it is necessary to determine smaller distances.
The circuit in Figure 1 is useful for measuring small distances to reflective
surfaces. Its measurement range is from less than 1 cm to approximately 20 cm for a
flat, white surface. ... |

IR Heart Pulse Monitor : Reverse engineered circuit diagram of a pulse
sensor circuit board out of a treadmill. Notice that the output is level shifted for
use by CMOS logic running on 4.5V regulated down from the 6V battery. The CMOS logic
also controlls the power to the analog circuitry and infrared LED. I do not gaurantee
the accuracy or safety of any information herein.

IR Modulation Detector: A circuit to extract and measure the modulated
carrier of an Infra Red remote control. Note that the circuit does not physically
separate control pulses from modulation, but amplifies the completereceived signal
allowing the waveform to be displayed ideally on an oscilloscope or a frequency
counter. Modulation frequencies between 1kHz and several MHz may be measured.
