How to use the wireless multi sensor development kit with customizable app for
IoT and wearable sensor applications
Introduction
The
STEVAL-MKSBOX1V1
(SensorTile.box) is a ready-to-use box kit with wireless IoT sensor platform designed to help you
build apps that use motion and environmental sensors, regardless of your level of expertise.
The hardware node is a board that fits into a small plastic case (IP54) with a rechargeable battery. You can connect with your
smartphone to the board via Bluetooth by using the
ST BLE Sensor
app (available both on Google Play and Apple Store) and
immediately build your own apps through a special interface that offers beginner and expert level functionality. This multi-sensor
kit therefore allows you to design wireless IoT and wearable sensor applications quickly and easily, without performing any
programming.
SensorTile.box includes a firmware programming and debugging interface that allows professional developers to engage in
more complex firmware customization using the STM32 Open Development Environment (STM32 ODE), which includes a
sensing AI function pack with neural network libraries.
The kit board includes an embedded
SPBTLE-1S
Bluetooth SMART application processor that is compliant with BT
specification v4.2. This transmitter module is FCC (ID:S9NSPBTLE1S) certified and IC (IC:8976-SPBTLE1S) certified.
