EV-STRUCTURAL-ARDZ Sensor for Structural Monitoring
Overview
The EV-STRUCTURAL-ARDZ is a vibration sensor that uses the ADXL343 digital output MEMS accelerometer chip and the ADIS16203 programmable 360° inclinometer. Aside from providing vibration data, this board also features the MAX30210 digital temperature sensor which gives the option to shut down sensitive machines and equipment for smart motor sensing applications. This vibration sensor can also detect if the horizontal position of the sensor changes, which points towards a collapse of the structure where the sensor was deployed.
Features
| Temperature Sensor |
|---|
| ±0.1°C accuracy from +20°C to +50°C |
| ±0.15°C accuracy from -20°C to +85°C |
| High and low temperature alarms |
| Accelerometer |
| Built-in motion detection features make tap, double-tap, activity, inactivity, and free-fall detection trivial |
| Multipurpose accelerometer with 10- to 13-bit resolution for use in a wide variety of applications |
| Inclinometer |
| Digital self-test function |
| Configurable alarm function |
| ±180 output format option |
Applications
- Smart motor sensor
- Tilt sensing, inclinometers
- Platform control, stabilization, and leveling
- Motion/position measurement
- Monitor/alarm devices (security, medical, safety)

Components and Connections
Digital Interface (Arduino)
The Arduino interface is a standardized digital interface for various digital communication protocols such as SPI, I2C, and UART. These interface types were standardized by Arduino, which is hardware and software company. Complete details on the PMOD specification can be found here.
The pin map for the Arduino pins is described in the table and its schematic diagram below.
Sensor Device
The board comes with the ADXL343 3-Axis MEMS Accelerometers, ADIS16203 Programmable 360° Inclinometer, and MAX30210 ±0.1°C Accurate, 16-Bit Digital I2C Temperature Sensor.
Applications
The EV-STRUCTURAL-ARDZ can be used with the MAX32670-SX-ARDZ Base Board, which is a long-range wireless radio development platform based on MAX32670 ultralow power ARM Cortex-M4 microcontroller and SX1261 RF transceiver.
Using these platforms together enables users to design solutions based on low-power, long range proprietary radio communication technique.

System Setup
PHASE 1: Hardware Setup
Note that this setup only applies for MAX32670-SX-ARDZ Base Board. Users may use a different base board or microcontroller, however the firmware built for this demo application cannot be used as this is specifically designed for the MAX32670-SX-ARDZ.
Equipment Needed
- One (1) MAX32670-SX-ARDZ Base Board
- One (1) EV-STRUCTURAL-ARDZ Sensor Node
- One (1) MAX32625PICO Rapid Development Platform with 10-pin ribbon cable
- with firmware image: MAX32625PICO Firmware Image for MAX32670
- One (1) CR123A Battery or any equivalent external DC power supply (+3 V to +4.7 V)
- Note that this is not included in the kit
- One (1) Micro USB to USB cable
- Host PC (Windows 10 or later)
- Insert one CR123A battery (3 V to 4.7 V) into the battery holder (BT1 connector) of the MAX32670-SX-ARDZ Base Board.
Make sure to check for the battery polarity in the BT1 connector, refer to the figure below. The DS3 LED will light up indicating that you have inserted the battery correctly and that power is provided in the base board.
- Connect the EV-STRUCTURAL-ARDZ Sensor Node to the MAX32670-SX-ARDZ Base Board by aligning the corresponding Arduino headers on each board.
- Connect the MAX32625PICO programming adapter to the MAX32670-SX-ARDZ Base Board through the 10-pin ribbon cable.
Make sure that the MAX32625PICO programming adapter has been flashed with the correct image before connecting it to the MAX32670-SX-ARDZ Base Board. If you do not know how to load the image, click on the instructions below:
- Connect the MAX32625PICO programming adapter to the Host PC using the micro USB to USB cable.
Once you have completed this setup, proceed to PHASE 2 found in ADI Long Range Wireless Radio Software User Guide.
