· 0. However, using your IR light source, you should be able to adjust your IR sensor to distinguish between a glossy white tape, and a flat black (for minimal reflection) tape. Not necessarily. White and black, meaning high and low reflectance, in the visible range does not guarantee high and low reflectance in IR.
· The black wire is the output (load) wire of the sensor. 3wire DC sensors can have a PNP (sourcing) or NPN (sinking) output. Just make sure the correct sensor part number is selected for the correct transistor circuit. So there you have it! As you can see wiring a 3wire sensor is not too difficult. PNP N/O PNP N/C NPN N/O NPN N/C
· Brief about IR Sensor Module. The IR sensor module consists mainly of the IR Transmitter and Receiver, Opamp, Variable Resistor (Trimmer pot), output LED along with few resistors. IR LED Transmitter. IR LED emits light, in the range of Infrared frequency. IR light is invisible to us as its wavelength (700nm – 1mm) is much higher than the ...
· The infrared sensor, also known as IR sensor, is a device that detects reflected light and emits infrared light. It can therefore differentiate between black and white or dark and light. There are many types of infrared sensor, such as the ones found in TV remote controls, object detection or even for measuring a person´s heart rate.

Infrared transmitting (IRT) sheet was specifically formulated for projects requiring ultraviolet (UV) and visible light blockage while allowing infrared (IR) transmission starting about 750nm. The physical properties of this product are the same as standard extruded sheet and thus the same fabrication techniques apply.
· An infrared sensor is an electronic device, that emits in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the types of sensors measures only infrared radiation, rather than emitting it that is called as a passive IR sensor.
Black Globe Temperature Sensor (BG40 Series) Features • Microprocessor accuracy • Frequency output • Robust signal (up to 250m cable no loss) • Sensors fully interchangeable with no software adjustment • Semiconductor sensing element • Waterproof, aluminium sheathed tip • Robust housing • Standard 6” Copper globe
Night Vision (Builtin IR Illuminators): Many dome cameras come equipped with infrared (IR) illuminators and a progressive CMOS sensor. This combination enables unparalleled lowlight camera performance for up to ranges of 30 meters or more, for both indoor and outdoor use. Types of Dome Cameras:
· Remote sensing instruments are of two primary types: Active sensors, provide their own source of energy to illuminate the objects they observe. An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or ...
