A flexibly usable optoelectronic sensor device for detecting an object, comprising a receiving device for receiving light backscattered after the scattering of an emitted light beam at the object, wherein the receiving device has an array of at least two receiving elements for detecting radiation and a receiving optical unit for imaging the received radiation on the array; the array is divisible and/or divided into at least two array regions, wherein the at least two array regions correspond in each case to scatterings at objects at different distances from the monitoring region and/or different brightnesses of the received radiation, and the receiving elements respectively arranged in different array regions are settable and/or set to detect with mutually different light sensitivities.
