Let’s get started with Bluetooth environmental sensing!

Ble2-300x281.png


The Basic Kit is a small, coin cell powered development kit that includes a 4-Sensors leaf with temperature, humidity, illuminance and acceleration sensors, an AVR MCU leaf and a Bluetooth LE leaf.

It’s easy to send sensor information to a smartphone or computer via Bluetooth and to control the LEDs in the Basic Kit.

The Basic Kit has this program written into it that you can use right out of the box.

On the smartphone or computer side, an app called “Web Bluetooth” can be used to connect to the Basic Kit on any platform, with no installation required.
