Abstract
A proximity sensor having improved environmental compensation performance and an environmental compensation method in the proximity sensor are disclosed. The environmental compensation method and the proximity sensor advantageously reduce processing time, algorithm operation time, and power consumption by previously setting sensing values before sensing of sensors unlike a typical method in which compensation is carried out by multiplying factors obtained through software. Further, the environmental compensation method and the proximity sensor have an advantage of accurate compensation not only for linearly varying environmental factors but also non-linearly varying environmental factors.
