GENERIC-SENSORS-LITE

INTRODUCTION:

Lightweight implementation of W3C spec, targeting constrained devices.

Several JavaScript runtimes are supported (node.js, IoT.js using JerryScript)

USAGE:

Following sensors can be plugged on pins of your favorite single board computer:

• BH1650: for measuring illuminance (i2c=0x23)
• BMPx80: for measuring temperature, or any compatible sensor (ie: BMP180, i2c=0x77)

SETUP:

Privileged access to hardware resources is also required too (setup or use sudo).

For instance on Raspbian:

sudo raspi-config # Enable I2C
ls -l /dev/i2c* || sudo reboot
sudo apt-get install i2c-tools
/usr/sbin/i2cdetect -y 1

USING NODE.JS:

git clone --recursive https://github.com/rzr/generic-sensors-lite
cd generic-sensors-lite
npm install
npm test
(...)
log: temperature: 28.1
log: ambientlight: 51
log: temperature: 28.1
log: temperature: 28.1
log: ambientlight: 51
(...)

USING IOT.JS

For constrained environments:

make runtime=iotjs run
# (...)
# iotjs example/index.js 
# log: temperature: 31.8
# log: ambientlight: 16.666666666666668
# (...)

Note: It has been verified on GNU/Linux not TizenRT yet (TODO).

DEMO:

An extra example is provided to show integration in Mozilla's Thing project. Sensors are powered by webthing-iotjs and monitored on dashboard as progressive web app (PWA).

Usage:

make runtime=iotjs run
make -C example/webthing runtime=iotjs run
# (...)
# log: AmbientLight: AmbientLight: change: 28.333333333333336
# log: Temperature: Temperature: change: 33
# (...)

Respectively node could be supported too, just adapt to webthing-node API instead of webthing-iotjs (TODO):

make -C example/webthing runtime=node run
# (...)
