1. Introduction
The sensor puck demonstrates Silicon Laboratories optical sensor (Si1147-M01) RH and temperature sensor
(Si7021) and low power MCU (EFM32G210 "Gecko"). The data is broadcast using a Bluetooth Low Energy (BLE)
module and can be displayed on a mobile device (Apple iOS or Android) that supports the BLE protocol.
By using broadcast mode, a connection does not have to be established, making it possible to display the data
from several modules at the same time.
2. Evaluation Kit Description
Figure 1. Silicon Labs Sensor Puck
The evaluation kit consists of a sensor puck with a battery and the on/off switch in the off position. Install the battery
if it is not installed. The + terminal of the battery faces away from the board towards the + terminal of the battery
holder. Remove the pull tab separating the battery from the battery holder if needed. When the switch is turned on,
the puck will automatically start taking and broadcasting data. For the puck itself, there is no installation required.
