Abstract:

An occupancy sensor (S) includes: - a sensing probe (101) to detect occupancy (P) of a space monitored by the sensor (S) and produce a corresponding sensing signal, - a comparator (104) including a voltage divider (RA, RB, R1, R2, R3, RC) defining a comparison value (A, B) against which the sensing signal is compared to detect occupancy, and - a voltage sensing means (105) to sense a feed voltage (V battery ) applied to the sensor (S), wherein changes in the feed voltage (V battery ) to the sensor induce a change in the comparison value (A, B). The voltage divider (RA, RB, R1, R2, R3, RC) includes one or more resistors (R1, R2, R3) selectively switcheable (Q1, Q2, Q3) to counter changes induced in said comparison value (A, B) by changes in the feed voltage (Vbattery) • For instance, the voltage divider (RA, RB, R1, R2, R3, RC) may define a comparison window for the sensing signal with a width between an upper threshold (A) and a lower threshold (B), and may include one or more resistors (R1, R2, R3) selectively switcheable (Q1, Q2, Q3) to counter changes in the width of the comparison window (A, B) induced by changes in the feed voltage ( V battery ) •

Abstract(Chinese):

占用传感器（S）包括： - 感测探头（101），用于检测由所述传感器（S）监视的空间的占用（P）并产生相应的感测信号; - 比较器（104），包括分压器（RB，R1，R2，R3，RC），其定义与感测信号进行比较的比较值（A，B）以检测占用;以及 - 电压感测装置（105），用于感测施加到传感器（S），其中与传感器的馈电电压（Vbattery）的变化引起比较值（A，B）的变化。分压器（RA，RB，R1，R2，R3，RC）包括可选择地切换（Q1，Q2，Q3）的一个或多个电阻器（R1，R2，R3）以对抗在所述比较值（A，B）通过馈电电压（Vbattery）°的变化例如，分压器（RA，RB，R1，R2，R3，RC）可以定义感测信号的比较窗口，其宽度在上阈值（A）和下限阈值（B），并且可以包括可选择性地切换（Q1，Q2，Q3）的一个或多个电阻器（R1，R2，R3）以对抗由馈电变化引起的比较窗口（A，B）的宽度变化电压（Vbattery）°
