Input voltage and Quiescent current To make the quiescent current lower, Q1 can not be triode, but MOS transistor. Also need to adjust the R1 according to the input voltage, the current of R1 is less than 100uA: Input voltage R1 3.3V 3K 4V 10K 5V 20K 6V 30K 9V 68K 12V 15V 100K 120K If use Triode, R2 (current limit resistor) must be added. 2. Sensitivity adjustment A voltage applied to the SENS input sets the threshold used to detect a PIR Signal between the PIRIN and NPIPIN inputs.VSS selects the minimum threshold voltage.Any voltage above VDD/4 will select the maximum threshold,which is the least sensitive setting for PIR signal detection. -----------------------------------------------------------------------------------------------------www.nysenba.com------------------------------------ 3. Light adjustment If VDD=3V, and voltage rises from low to high, when it is higher than 0.4DD(1.2V),Vout enables. Voltage decreases from high to low, when lower than 0.2VDD(0.6V),Vout disables. -----------------------------------------------------------------------------------------------------www.nysenba.com------------------------------------ 4.

A) in rapid environmental changes B) in strong shock or vibration C) in a place where there are obstructing material (eg. glass) through which IR cannot pass within detection area. D) exposed to direct sun light E) exposed to direct wind from a heater or air condition NANYANG SENBA OPTICAL AND ELECTRONIC CO. LTD.
