How to use the STEVAL-BLUEPIRV1 evaluation board for Bluetooth ® Low
Energy wireless motion detector based on a PIR sensor
Introduction
The STEVAL-BLUEPIRV1 evaluation board is an application example design of a wireless motion detector based on a passive infrared (PIR) sensor and featuring Bluetooth ® Low Energy wireless connectivity.
The passive infrared sensors are the most used sensors for motion detection, thanks to their low-power consumption and price.
The STEVAL-BLUEPIRV1 evaluation board uses IRA-S210ST01 by Murata. The detection range of the IML-0688
Fresnel lens is up to 5 m.
The on-board low-power TSU102 CMOS op-amp and TS883 comparator perform the analog signal conditioning with a power consumption in a sub-µA range.
The embedded BlueNRG-M2SA FCC and IC certified radio module (FCC ID: S9N-BNRGM2S and IC: 8976C-
BNRGM2SA), which integrates an application microcontroller based on an Arm
®
Cortex
®
-M0 core, features the
Bluetooth ® Low Energy connectivity.
The whole design has been built by focusing on low-power consumption. Even though powered via a CR2032 coin-cell battery, the board expected lifetime is around a year.

Overview
Overview
•
•
•
•
•
The STEVAL-BLUEPIRV1 evaluation board comes ready-to-use and working out-of-the-box. It provides all the functionality expected from a wireless motion detector.
Some LEDs show the Bluetooth ® Low Energy status and motion detection. Then, using the STBLESensor app, you can visualize the battery status and signal strength as well as the motion indication.
The Bluetooth ® Low Energy module is separable to allow the designer to use the analog part only.
The supply and output reading are available on a separate header and all the analog signals are placed on a testing point.
The STEVAL-BLUEPIRV1 features:
• BlueNRG-M2SA module for Bluetooth ® Low Energy communication
Connectivity with the STBLESensor app
Analog signal conditioning based on the TSU102 operational amplifier
Window comparator based on the TS883 open-drain comparator
Power management based on the STLQ020 ultra-low quiescent LDO
Powered by a single CR2032 coin cell battery

Getting started
2 Getting started
To use the STEVAL-BLUEPIRV1 , you just need to insert the battery and download the STBLESensor app on your smartphone.
2.1
Battery
The STEVAL-BLUEPIRV1 is powered through a CR2032 coin cell battery.
Insert the battery into the holder placed at the board bottom.
Important: Use CR2032 lithium 3 V batteries only. Insert the battery with the positive (+) terminal facing out.
Caution: Risk of fire or explosion if the battery is replaced by an incorrect type or if the battery polarity is inverted. Use only IEC 62133 certified CR2032 batteries.
Figure 4. STEVAL-BLUEPIRV1 battery insertion
2.2
Indication LEDs
There are two indication LEDs available on the board. The orange LED indicates the movement whereas the blue
LED indicates the connection over Bluetooth ® Low Energy.
The orange LED lights up right after the battery is inserted. It takes around 10 seconds to stabilize the analog circuitry and perform the proper movement indication. The orange LED is switched off shortly after the movement stops.
The blue LED periodically blinks only when the Bluetooth ® Low Energy connection is set up.

Low Energy device using the BlueST
The app shows various panels with the application data. It is available at Google Play and App Store.

When the device scanning is performed with the STEVAL-BLUEPIRV1 active in the smartphone range, the board should appear in the list as BluePIR.
Figure 6. Device list

By clicking on BluePIR, the smartphone connects to the STEVAL-BLUEPIRV1 . The user interface with board information then appears.
There are two panels available when successfully connected to STEVAL-BLUEPIRV1 .

Firmware
Firmware
•
•
The evaluation board comes flashed with a firmware based on the STSW-BLUENRG1-DK . This software package contains several project examples, such as the BLE_SensorDemo_BlueMSapp with few modifications:
• low-power mode selected to achieve sub µA power consumption when idle
Bluetooth ® Low Energy messages modified to show only the LED panel in the STBLEsensor app
ADC to measure the battery voltage
You can modify the firmware according to your needs. Then, load it into the BlueNRG-M2SA module via the SWD available on the board and use the STSW-BNRG1STLINK software package.
The Bluetooth ® Low Energy module is used in low-power mode and the SWD peripheral is disabled. The
STSW-BNRG1STLINK is able to connect only after the device reset.
