A device and method for detecting scattered light signals is specified. A light source (10) shines light onto a scattered light zone (15), in which particles can be found. With the aim of reducing costs and improving detection accuracy, the device (100) has a plurality of optical sensors (21, 22, 23, 24, 25, 26, 27, 28, 29, 30) for detecting scattered light and an analyser device for analysing the signals detected by the optical sensors, wherein the sensors (21, 22, 23, 24, 25, 26, 27, 28, 29, 30) are each arranged at a sensor angle (W1, W2, W3, W4, W5, W6, W7, W8, W9, W10) relative to an incident axis (11) of the incident light to detect scattered light from the scattered light zone, wherein one of the plurality of optical sensors (21, 22, 23, 24, 25, 26, 27, 28, 29, 30) is a reference sensor, and wherein the analyser device is designed to relate waveforms from the remaining optical sensors to the waveform of the reference sensor, wherein the waveforms of the optical sensors (21, 22, 23, 24, 25, 26, 27, 28, 29, 30) are used to classify any particles found in the scattered light zone (15).
