4. SensorTile
Simple, powerful, extendible
Designed to fit your needs:
• Used as a standalone sensor node to MONITOR, TRACK and REMOTELY CONNECT to a Smartphone App
(Android/iOS)
• Easily plug into new designs to add SENSING and CONNECTIVITY capabilities through a SMART HUB solution
Engineered for makers and developers:
• Standalone mode:
Turn it on, configure it via BLE and start acquiring sensor data remotely on your Smartphone
• Sensor and Connectivity HUB mode:
Plug the SensorTile into new designs and access all features through a convenient command interface (I2C/SPI/UART)
• Programmable development kit:
Leverage on the on-board STM32 processing capability and provided software API to create your new BLE-connectable
sensor node
An all-ST Reference Design

16. Hint
Customizing the ST Wearable Mockup

HTS221
Humidity and
Temperature sensor
• Cradle-mounted humidity and temperature sensor shows
that not all the sensors must be on the Core System
• The simple 2-layer Cradle can be easily redesigned to
accommodate any ST sensor or actuator you may want
to field-test
• There is no need to modify the highly optimized
SensorTile Core System to do that!
Use the cradle as a reference design for other wearable solutions
using the same SensorTile Core System
