    Overview

    The SENSOR-PUCK provides a convenient development and demo platform for Silicon Labs’ Si114x Optical Sensors and Si701x/2x Relative Humidity and Temperature Sensors. The coin-cell battery operated SENSOR-PUCK is controlled by an EFM32™ energy friendly MCU. A Bluetooth Low Energy (BLE) module is used to broadcast sensor data to iOS or Android smartphones with the downloadable SENSOR-PUCK app. Place your finger tip over the Si1147 sensor to measure heart rate. Environmental sensing of UV Index, ambient light, relative humidity, and temperature is also provided. For power management, the board features a Touchstone TS3310 boost DC/DC converter.
