“…The alternate current (AC) impedance of the LED receiver can be controlled by the injected light [14]. InGaN-based or InGaAsP-based phototransistors have also been studied [15], [16]. The former is advantageous in low dark current and high responsivity of the white-LED based VLC receivers.…”

An IoT optical sensor based on the series-connected RGB LEDs is designed, which exhibits the light-controllable optical-to-electrical response like a phototransistor. The IoT sensor has the maximal AC and DC responsivities to the violet light mixed by blue and red light. Its responsivity to the blue light is programmable by the impinging red or green light. A theoretical model based on the light-dependent impedance is developed to interpret its novel optoelectronic response. Such IoT sensor can simultaneously serve as the transmitter and the receiver in the IoT optical communication network, thus significantly reduces the system complexity.
