The SensorTag kit connects six (6) sensors to TI’s CC2541 Wireless MCU that features Bluetooth Low-Energy (BLE) connectivity. The sensors are temperature, humidity, pressure, accelerometer, gyroscope and magnetometer. It seems to me that connecting some of these to a BeagleBone Black could be pretty handy for collecting environmental data, so I decided to try it out. (disclosure: I work on BeagleBone Black and for TI, so I figure my employers wouldn’t mind me doing this on company time either.)
It turns out grabbing data from the SensorTag using a Bluetooth dongle and Node.JS on BeagleBone Black was rather easy. Working with the MQTT tools still remains a bit of a challenge for me.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
