Sensor EXP Evaluation Board USER’SGUIDE

1. Introduction

This Sensor-EXP-EVB is a hardware plugin card for the EFM32 starter kits (STKs). It contains the Si7013 humidity

and temperature sensor as well as the Si1147 UV and proximity sensor. A weather station software demo is

available to download to the Zero or Tiny Gecko STK through simplicity studio. When downloaded to the

EFM32ZG-STK3200 Zero Gecko STK or the EFM32TG-STK3300 Tiny Gecko STK, the demo displays humidity,

temperature, and UV index and performs gesture detection. Right or left gestures move the display type and, on

the temperature screen, up or down gestures move the display between °C or °F.

1.1. Features

Si7013 Humidity and Temperature sensor

Si1147 proximity sensor

3 IR LEDs for gesture detection

20-pin expansion header

Battery operation with long battery life

1.2. Getting Started

The first step to get started with your new Sensor-EXP-EVB is to go to www.silabs.com/simplicity-studio.

The simplicity studio software package contains all the tools, drivers, software examples and documentation

needed to use the Sensor-EXP-EVB.

You will need to connect the Sensor-EXP-EVB to the EFM32ZG-STK3200 Zero Gecko STK or the EFM32TG-

STK3300 Tiny Gecko STK. The demo code can be loaded using the USB cable and J-Link debug interface.

2. Weather Station Demo

2.1. Loading the Demo

Connect the USB cable to the STK and launch Simplicity Studio. Click on “Detect connected device” then click on

the Demos button (top right) and select the Sensor-EXP weather station demo from the list. Make sure the Bat/Dbg

switch on the STK is set to DBG and click Start to download the demo. The following figures show the Zero Gecko

STK screens.

2.2. Using the Demo

After download, the USB cable can be disconnected and the demo will run from battery power by switching the

Bat/Dbg switch to battery.

The demonstration will first show a start screen with some basic instructions. In order to conserve power the

demonstration code wakes up every few seconds and looks for a proximity event before looking for gestures. To

initiate a proximity event, hold your hand (with fingers closed) over the Sensor-EXP-EVB. Once the proximity event

has been detected, gesture detection is enabled. The gesture control state is fairly high-power compared to the idle

state, so the code will automatically terminate gesture detection after one minute of inactivity. Swiping your hand

across the Sensor-EXP-EVB in left and right motions will change the display as shown in Figure 5.

Figure 5. Displays

While on the temperature display, an up or down swipe motion will change the units to °C or °F.

5. Connectors

On the left hand side of the board there is a right-angle 20-pin expansion header is to allow connection to the

EFM32 STK board. This connector is not currently compatible with Wonder, Giant, or Leopard Gecko STKs.

However, with hardware modifications, the sensor-EXP-EVB can be used with these STKs as well. On the right

hand side of the board there is another connector to allow connection to another plugin card. J6 is a flat ribbon

cable connector to connect other devices such as additional sensors to the I2C bus.

6. Schematics, Assembly Drawings and BOM

The schematics, assembly drawings and bill of materials (BOM) for the Sensor-EXP-EVB are available through

simplicity studio when the EXP documentation package has been installed.
