node-red-node-sensortag
|
|
=======================
|
|
|
|
This node adds support to Node-RED to read from the Texas Instruments SensorTag.
|
|
|
|
Pre-requisites
|
|
--------------
|
|
|
|
You will need a suitable Bluetooth Low Energy (BLE) stack and drivers for your hardware
|
|
- for example Bluez 5.2.x or better.
|
|
|
|
#### Raspberry Pi
|
|
|
|
Install Bluetooth drivers and bluez stack, and set executable by non-root user
|
|
|
|
sudo apt-get install libbluetooth-dev libudev-dev pi-bluetooth
|
|
sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)
|
|
|
|
|
|
Install
|
|
-------
|
|
|
|
Run the following command in your Node-RED user directory - typically `~/.node-red`
|
|
|
|
npm i node-red-node-sensortag
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
The SensorTag is a Bluetooth LE device hosting the following sensors:
|
|
|
|
* Humidity and Temperature
|
|
* Ambient & IR Temperatures
|
|
* Barometric Pressure
|
|
* 3 axis Accelerometer
|
|
* 3 axis Gyroscope
|
|
* 3 axis Magnetometer
|
|
* 2 push Buttons
|
|
* 1 Luxometer (CC2650 version only)
|
|
|
|
The config node allows the user to enable/disable any of the sensors listed above. The readings from
|
|
these sensors will be sent as a JSON object payload with the sensor name appended to the topic provided:
|
|
|
|
* Humidity - { topic: [topic_prefix]/humidity , payload: { temp: 21.2, humidity: 88} }
|
|
* Temperature - { topic: [topic_prefix]/temperature, payload: { ambient: 21.2, object: 33.0 } }
|
|
* Barometric Pressure - { topic: [topic_prefix]/pressure, payload: { pres: 1000 } }
|
|
* Accelerometer - { topic: [topic_prefix]/accelerometer , payload: { x:0.0, y:9.8, z:0.0 } }
|
|
* Magnetometer - { topic: [topic_prefix]/magnetometer , payload: { x:0.0, y:0.0, z:0.0 } }
|
|
* Gyroscope - { topic: [topic_prefix]/gyroscope , payload: { x:0.0, y:0.0, z:0.0 } }
|
|
* Luxometer - { topic: [topic_prefix]/luxometer , payload: { lux: 212 } }
|
|
* Buttons - { topic: [topic_prefix]/keys , payload: { left: true, right: false} }
|
|
|
|
**Note**: This sensorTag library only supports using 1 SensorTag at a time.
