Introduction
With this goodie ON Semiconductor together with ‘the things.IO’ and Sigfox are demonstrating a real case example on how
easy can the AX-SFEU certified single chip solution SoC (API version) be combined with the an NCS36000 passive
infrared (PIR) detector to develop an IoT product configurable in few clicks to operating on the Sigfox network.
This product is ETSI and Sigfox certified and comes with MyPIR application (IOS, Android) and an one year Sigfox
subscription.

Goodie DESCRIPTION
In order to let the user understand what the Goodie is doing, some visual feedbacks are provided. Thus 3 LEDs are mounted
close to the PIR sensor (under the lens). Each LED has a specific meaning, here briefly summarized:
close to the PIR sensor (under the lens). Each LED has a specific meaning, here briefly summarized:
YELLOW
: PIR movement detection event.
RED
: Sigfox communication in process.
GREEN
: result on Sigfox communication.
A micro switch for turning ON/OFF the goodie is also present to prevent any energy consumption when not needed.
SIGFOX COMMUNICATION AND Goodie SW STRATEGY
Sigfox is a network provider and in order to have access to this infrastructure, a contract has to be signed with them. Thus,
every goodie is already provided with a subscription for one year that enables up to 140 uplink messages per day.
Since the myPIR goodie could be placed anywhere, in case of a very crowded place the limit of 140 messages could be hit
in a very short time. Hence the SW is taking care about this constraint limiting to 6 messages per hour the communication
with the cloud.

FIRST POWER UP
When the myPIR goodie is powered up for the first time by toggling the switch from OFF to ON (bottom side of Figure 1)
the AX-SFEU-API SW will start to initialize both the RF transceiver and the additional IOs while the NCS36000 controller
will start initializing himself. The energy is provided by two AAA battery mounted on the bottom side of the PCB.
The initialization phase is clearly identifiable because the YELLOW led will start toggling at fixed rate for about thirty
seconds (NCS36000 initialization) and after approximately ten seconds from power up, the RED led will blink 3 times for
overall 6 seconds approximately. The microcontroller is sending a Sigfox message over the Sigfox cloud in order to say
