CC2541 SensorTag Development Kit



The first generation CC2541 SensorTag is no longer available. For new IoT designs, the next generation CC2650 SensorTag is now available as a full development platform for sensing and cloud connectivity applications. To develop on the CC2541, please use the CC2541 Mini Development kit.

The CC2541 SensorTag is the first Bluetooth Smart development kit focused on wireless sensor applications and it is the only development kit targeted for smart phone app developers. The SensorTag can be used as reference design and development platform for a variety of smart phone accessories.

TI is making Bluetooth low energy app development easier and faster with the CC2541 based SensorTag, which has all the commonly used sensors on a single board for quick evaluation and demonstration. The SensorTag works with TI’s TPS62730 (step down converter), and includes TI’s TMP006 IR MEMS temperature sensor, humidity sensor, pressure sensor, accelerometer, gyroscope and magnetometer. The versatility of the SensorTag means limitless app possibilities including those for health and fitness, medical, educational tools, toys, remote controls, mobile phone accessories, proximity and indoor locationing.

The CC2541 SensorTag kit shortens the design time for Bluetooth low energy app development from months to hours with no embedded software design knowledge required. The SensorTag is preprogrammed with the FW needed to get started with smart phone app development and TI has a SensorTag App on the App Store providing developers easy access to the tools and software examples they need.

For more information and links to apps downloads please refer to technical information and user guides please refer to the SensorTag wiki page.

SensorTag now supports iBeacon™ technology

The SensorTag now supports iBeacon technology, allowing you to quickly and easily evaluate iBeacon for "indoor GPS" applications. iBeacon can be used to customize apps on a smartphone or tablet, based on location: a functionality that is being used by many retail shops, museums and restaurants to display relevant information to users. iBeacon technology can be integrated into mobile appcessories, asset trackers, home automation systems, alarm and security systems, point of sale devices, automobiles, industrial applications and a wide variety of consumer electronics and appliances. For more information on how to use the Sensortag with iBeacon, watch the video in the video section below or visit the SensorTag Wiki.

The new location app with iBeacon technology is available to download on the App Store for iPhone, iPad and iPod touch. SensorTags can be upgraded to be compatible with the iBeacon technology using the latest SensorTag App. To upgrade your SensorTag to be compatible with iBeacon technology, sign up to become an iBeacon licensee with Apple, then request access to the software by visiting the SensorTag software page.
