STEVAL-IDS002V1
Autonomous wireless multi-sensor node powered by PV cells and
based on SPV1050 (SPIDEr™)
Data brief
Description
The STEVAL-IDS002V1 device is a complete fully
configurable energy reference design wireless
sensor node powered by a photovoltaic module
soldered on the top. It is composed by a fully
integrated transmitter board which contains a
temperature sensor, an air pressure sensor and a
3-axis accelerometer MEMS sensor powered by
the SPV1050 device. Moreover a microcontroller
and an RF Sub-Giga transmitter all by ST are on
board. The system has a receiver companion
powered through a USB cable by the PC. For
further details on the SPV1050 device please
refer to the related datasheet. The reference
design kit is supported by a software user-friendly
GUI able to show PV module and battery
electrical characteristics, conversion efficiency,
MPPT accuracy and sensors readings.
The transmitter module is based on an
STM32L151 low power microcontroller which
controls sensors configuration and data
communication. A digital temperature sensor
(STTS751), a pressure sensor (LPS331AP) and a
3-axis accelerometer (LIS3DH) are connected to
the microcontroller through the I2C bus.
Features
• Autonomous wireless sensor node based on
ULP energy harvester and battery charger
SPV1050
• Typical use case with 3-axis accelerometer,
temperature sensor and air pressure sensor on
board
• PV module soldered on top
• Lithium coin-cell battery
• User-friendly software GUI for system
configuration
• It can be used with power monitoring board for
efficiency and all fundamental electrical
parameters measurement
• RF receiver board powered by USB
• All ST component offer
