SpecificationsPeak sensitivity wavelength: 860nmCollector dark current (Ee=1mW/cm2): 100nAOperating Temperature: -25ºC ~ +85ºCFigure 10: IR sensorFigure 11: Photo Current vs. Irradiance taken from the Premier Farnell Group sensor data sheet-10- v4.0
Sensors3.3.2. UsageWith this sensor we can know the level of IR light and we can decide if enable the IR cut filter filtering the IR light or disable theIR cut filter allowing the pass to all light.3.3.3. Measurement processThis is a transistor in wich the current of this base varies depending on the intensity of the light received on its photoelectricpart. The current generated in base allow the conduction of current througth collector-emiter. The current produces a voltagein a resistance connected between the emmiter of the phototransistor and ground. The voltage of the resistance can be readthrough the analog-to-digital converter of the microcontroller.The sensor value can be read with the next function:{IR_value = readAnalog(SENS_IR);}3.3.4.
