Infrared remote control receiver for Media Centers
Some time ago, a media center box was created to replace a DVD player, satellite receiver, VCR, and PlayStation 2 with a single device. A Core 2 Duo processor system successfully replaced all these electronic devices. However, a remote control...
Infrared Remote Control Tester
Using a battery, a phototransistor, and a visible-light LED, this simple circuit functions as a "go/no go" tester for infrared remote control devices. The illumination of the LED indicates that the phototransistor is being modulated by infrared energy.
This circuit operates...
Light Control System (OP295)
Sensing unit consists of infrared emitter OP295 to produce the infrared beam, and two detectors in front of the emitter to detect the infrared beam OP598. Since the main idea in this device is to know person direction; and so,...
ir infrared detector circuit diagram
Men often appreciate the convenience of television remote controls, which can sometimes frustrate their female partners. They tend to switch channels frequently, wanting to ensure they do not miss anything while a specific program is on. With the remote control...
On-off Infrared Remote Control
Most homes today have at least a few infrared remote controls, whether they are for the television, video recorder, stereo, etc. Despite this fact,
Infrared (IR) remote controls are ubiquitous in modern households, serving as convenient devices for operating various...
The passive human body infrared sensor circuit
Passive human body infrared sensor circuits are generally similar in design, although some may have fewer stages. The circuit illustrated is sourced from the NICERA manufacturer and is considered a classic example. The front-end stage consists of a low-frequency signal...
IR remote control dimmer light circuit diagram
This is an infrared emission circuit diagram. The NE555 circuit generates a 40 kHz pulse, which is sent by the infrared emission control SE303 after being amplified by VT. The remote receiver and infrared dimming circuit are composed of the...
On-off Infrared Remote Control
On-off Infrared Remote Control Circuit. Most homes today have at least a few infrared remote controls, whether they are for the television, video recorder, stereo, etc. Despite this, who among us has not cursed the limitations of these devices?
The on-off...
Infrared Switch Circuit
A simple infrared-controlled switch can be operated using a TV remote control. The load can be any AC-powered device connected to the relay. The load activates for three minutes before turning off and can be used to switch on a...
