PIR Motion Sensor PaPIRs How to Use

Technical information concerning all sensors (EKM and AMN)

Block diagram output circuit

1) Digital output with integrated amplifier and comparator

2) Analog output with integrated amplifier

Wiring diagram

1) Digital output

2) Analog output

Notes:	Digital output types: The output signal for the digital output type is from inside FET drain, therefore pull-down resistors are necessary. Please select an output resistor (pull-down concept) in accordance with V_OUT so that the output current is maximum 100μA. If the output current is more than 100μA, this may cause false alarms. If the microcomputer has a pull-down function, there is no need for a resistor as long as the output current does not exceed 100μA. Analog output types (EKMC26 series): In either case, a microcomputer or a resistor needs to be chosen in accordance to V_OUT, so that the output current is maximum 200μA.
