There's a curve in your device's datasheet that tells you exactly that: Combined with the line in the Characteristics table that tells you the sensitivity is 0.55 A/W at 850 nm, this gives you the sensitivity at whatever wavelength you are using. WebbThis reflective sensor houses an InGaAs PIN photodiode and LED in a compact package. The LED irradiates infrared light on the target object, and the photodiode signal generated from the reflected light is output digitally through an I2C interface.
