This is an IR beam breaking alarm ideal to use in entry or passages. It is based on the working of the popular IR sensor Module TSOP1738 which senses 38 kHz Infrared pulses from the IR LED of the ...

Simply playing these back out of the Raspberry Pi’s audio out and into the switch’s IR input through a tiny transistor circuit does the trick. Now they have a networked five-way HDMI switch ...

Here is the circuit of an ultra sensitive IR receiver that can be used to switch on various AC devices through an IR transmitter. It uses the Photo transistor L14F1 to detect IR signals from the ...

RFDN03C (DNC Mixer) is IR SSB Mixer used in transceiver application. The process used to design DNC Mixer is 0.1um GaAs pHEMT. This Mixer employs two ...

One thing is clear: mid-IR applications ... integrated circuit device), could in principle fabricate a mid-IR contact sensor with an on-chip integrated radiofrequency wireless transceiver for ...
