how to protect ir sensor from sunlight

Can we protect ourselves from infrared light?

· What makes up sunlight? The electromagnetic radiation from the sun that reaches the Earth’s surface can be classed into three broad types: UV: the most dangerous, responsible for sun burns and potentially carcinogenic. About 5 to 10% of the irradiation is of this type. Visible light: the part that our eyes can see. 40% of the energy arrives in this form. IR: felt as heat. It makes up the ...

Influence from sun light for IR sensor. | Micromouse USA

· As a matter of fact, most of the Micromouse use infrared sensor to keep distance with wall when running, and it’s very easy to be affected by environmental light(noise) consequently cause crash. This is obviously something you don’t want to see, and there are some ways to reduce the change from happening such as use pulse controlled IR LED to send a very high current to against ambient light. …

Why IR sensor doesn''t work in sunlight? Quora

In most design problems, you cannot prevent an infrared (IR) sensor from sensing sunlight. For if you try to block sunlight from the sensor, such as with an infrared opaque material or light guide, you are decreasing sensitivity. By blocking the sunlight, you would only decrease the sensing capability of the very device being used to sense the world.

Ambient Light Filter for Infrared (IR) Sensor ...

· Sunlight produces plenty of IR. For any IR detector to work in the presence of sunlight, you have to chop the IR sender at a kHz rate, use a highgain accoupled amplifier at the IR detector, followed by a synchronous ac demodulator to detect the chopping frequency, which is what the TSOP type of IR receiver does. A DC coupled system is doomed...

IR detector under direct sunlight Sensors Arduino Forum

· If you can''t aim well enough with a laser then try a bright red or IR led. Red leds put out enough IR to blind CCD cameras with IR filter in place (shine one on a webcam, what color is the dot on your screen?) and have loads more dispersal than your laser (read: a hell of a lot easier to aim, like a shotgun as opposed to a rifle). Set your detector deep to cut the angle of light coming to it and shade …
