SILICON LABS “Thunderboard”:
Read sensor data with energy-efficient BLE 5.2 technology
The Thunderboard EFR32BG22 from SILICON LABS has plenty of sensor power.
Here you can easily and quickly evaluate sensors in connection with current Bluetooth 5.2 technology. Four sensors are already integrated on the compact 30 x 45 mm board for testing:
- Si7021 sensor for relative humidity and temperature
- Si1133 UV index and ambient light sensor
- Si7210 Hall effect sensor
- TDK InvenSense ICM-20648 6-axis inertial sensor
The starter kit based on the Wireless System-on-Chip (SoC) EFR32BG22 Blue Gecko of the manufacturer [Link to Newsletter BG22 Equipped with 76.8 MHz clock frequency, 512 kB Flash and 32 kB RAM, the board consumes very little power. It is an ideal platform for energy-saving IoT and environmental projects.
The Thunderboard in its latest generation is an optimised development platform for your Bluetooth sensor solution. It is equipped with environmental or ambient sensors from SILICON LABS. These include the Si7021, which can be used to measure the temperature and relative humidity with high precision.
The Si1133 detects the UV index and ambient light. This enables control of a sun protection blind in accordance with defined criteria, for example. The ambient light sensor switches lighting devices on and off according to the measured brightness values.
Convenient control and information via smartphone
The values can be read on the smartphone via Bluetooth. Devices are easy to control via smartphone, as usual. This functionality is made possible by the Bluetooth BLE technology of SILICON LABS Blue Gecko in combination with a certified app.
