Development and demo platform for Silicon Labs' sensors

Silicon Labs' Sensor-Puck development tool provides a convenient 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 communicate sensor data to iOS or Android smartphones with the downloadable Sensor-Puck app. Users can place a fingertip 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.
