New SensorTag 2 from TI, description and close up photos.

New SensorTag 2 from TI is really great Bluetooth 4LE Devkit boasting  10 Sensors and low power MCU

Today I got new toy from TI, it is CC2650STK SensorTag2 DevKit from Texas Instrument.

I was looking long for a device whcih is BLE4 powered and has sensors on it, I was playing with some chinese made SensorTag 1 clones, which were really lacking any documentation. And when I saw new DevKit from TI i was really happy to order 2 of them!

Here what SensorTag 2 is:

  • More sensors!
    • Adds support for more low power sensors
    • 10 sensors including support for light, digital microphone, magnetic sensor, humidity, pressure, accelerometer, gyroscope, magnetometer, object temperature, and ambient temperature
  • Lower power
    • Longer battery life from your coin cell and enabler of battery less applications
  • High performance ARM Cortex M3 (CC2650)
  • Cloud connectivity
    • Access and control your SensorTag from anywhere
    • Seamless integration with mobile apps
  • DevPacks allows you to expand the SensorTag to fit your designs
    • Interchangeable between all SensorTag types
  • Complete development system
    • Expandable with $15 debug DevPack
    • Code Composer Studio compiler license included
  • Extreme flexibility for IoT applications
    • Enable ZigBee or 6LoWPAN through a firmware upgrade

    First really good blog !
    I have a few questions about the sensor tag CC2650STK and how to use it 🙂

    Is it possible to get the sensor’s data and treat those data by creating our own Android application and not by using the default app ?

    Thank you very much for your answer !

      Thank you for nice words, yes it is totally possible because Sensortag2 sends data via standard Bluetooth 4LE profiles. so you can use them in your application and do whatever you want with the data.

    I hope you can help me with this. The first question is are you available to develop an app for me utilizing the motion sensor only? I can explain you the details and it should not take you long at all because the concept is pretty simple. But I need your help with this. I have been emailing others without success in responding partially because I am not going thru the usual channels as I prefer to pay your fee directly to you. Can you help? If yes, I will email you back with the details and we go from there. My name is Jose, I am in the state of Texas. I am in the health care field and my email contact me please.

    Heìi, I have some question. Is it possible to recording the motion data from the sensor and if it is possible, how can I do it?

      Possible, but I don’t think there is any app out of the box for this.
