SECTION 1
OVERVIEW
Thank you for choosing the MOD-ZIGBEE-PIR development board from
Olimex! This document provides a User’s Guide for the Olimex MOD-ZIGBEE-
PIR sensor module. As an overview, this chapter gives the scope of this
document and lists the board’s features. The document’s organization is
then detailed.
1.1 Scope
The MOD-ZIGBEE-PIR is a motion detector unit equipped with passive infrared (PIR) sensor
which utilizes open source ZigBee stack, and has the option to be configured to use MiWi
stack. This guide focuses on MOD-ZIGBEE-PIR board.
1.2 Features
MRF24J40 + PIC18F26K20 with open source MiWi and Zigbee stack
PIR sensor motion detector, sends wireless alarm to Zigbee nodes when motion is
detected
RF Transceiver – MRF24J40 IEEE 802.15.4™ Standard compliant 2.4 GHz RF
transceiver
UEXT connector
to all boards with UEXT
mini ICSP connector
On-board antenna
On-board temperature sensor – TCN75A
Option for external power supply through EXT_PWR
EXT/BAT switch
Reset circuit
two user buttons
two status LEDs
RST button
2x1,5V AA battery holders
PCB: FR-4, 1.00 mm (0,039"), solder mask, silkscreen component print
Dimensions: 93 mm x 32 mm (3.66’’x 1.2’’)

1.3 Board highlights
Perfect board for sensor networks with its PIR sensor and built-in temperature sensor.
The bundle PIC18F26K20 + mini ICSP + 2 buttons + 2 LEDs (green and red) + reset button
means that the board can be reprogrammed and used as a development board and allows
modifications.
Two supported free stacks – Microchip’s MiWi or ZigBee.
Three ways of powering the board via batteries, via external power supply, via ICSP
programmer.
The board has UEXT connector for easier communication.
FR-4 is the most used glass-reinforced epoxy laminate for PCBs.
1.4 Similar boards
MOD-ZIGBEE-UEXT is a version of MOD-ZIGBEE-PIR without the motion detection sensor. It
is supplied by a single battery and has a female UEXT connector. MOD-ZIGBEE-UEXT is
thinner than MOD-ZIGBEE-PIR because of the different battery types used for battery
powering of the board.
1.5 Organization
