Using this optical remote switch, you can switch on/off any electrical or electronic load. Like any remote control system, it has a mini transmitter unit (Fig. 1) and a receiver unit (Fig. 2) to ...

First of all, let us observe its circuit diagram to understand it clearly. This circuit is built around a 3-pin IR IC receiver TSOP 1738 that can detect 38 kHz burst frequency generated by a TV remote ...

The circuit is an electronic switch. You can control the whole functionality, change fan speed, turn on or off the lights etc. from your couch or bed using IR remote, Here, I programmed it for 3 types ...

Remote control distance: 30 m; Remote control battery: 23-A/12-V type; What’s Inside. Pulling the master unit apart, I find nothing more than an ordinary printed circuit board: an extremely simple ...

Remote operated switch circuit. IR receiver module TSOP 1738 (IRX1) is used to sense the pulsed 38kHz IR rays from the TV remote handset. The IR receiver module has a PIN photodiode and a preamplifier ...
