The present disclosure describes proximity sensor modules that include a time-of-flight (TOF) sensor. The module can include a plurality of chambers corresponding, respectively, to a light emission channel and a light detection channel. The channels can be optically separated from one another such that light from a light emitter element in the light emission chamber does not impinge directly on light sensitive elements of the TOF sensor in the light detection chamber. To achieve a module with a relatively small footprint, some parts of the TOF sensor can be located within the light emission chamber. 1. A proximity sensor module comprising:a light emitter element to generate light, at least some of which is directed out of the module; anda time-of-flight sensor including spatially distributed light sensitive elements and including circuitry to read and process signals from the light sensitive elements; andthe module having a plurality of chambers, wherein the light emitter and a first group of the light sensitive elements are in a first one of the chambers, and wherein a second group of the light sensitive elements is in a second one of the chambers,wherein the first and second chambers are optically separated from one another such that light from the light emitter does not impinge directly from the light emitter onto the second group of light sensitive elements in the second chamber.2. The proximity sensor module of including an interior wall to separate the first and second chambers claim 1 , wherein the interior wall has a bridge portion extending over a surface of the time-of-flight sensor.3. The proximity sensor module of wherein the second group of light sensitive elements includes detection pixels arranged to provide signals for determining a proximity of an object outside the module.4. The proximity sensor module of wherein the first group of light sensitive elements includes reference pixels arranged to provide signals for compensating for drift or to ...
