USB Library for the Ambient Weather WS-3000

Pull the current temperature and humidity levels for up to 8 remote sensors. Designed for Node.js.

Usage

npm install EpicVoyage/ambientweather-ws3000

async function main() {
  let ws3000 = require('ambientweather-ws3000');
  let sensors = await ws3000.query();
  for (let x = 1; x <= 8; x++) {
    if (sensors[x].active) {
      console.info('Sensor', x + 1, 'Temperature:', sensors[x].temperature + '°C, Humidity:', sensors[x].humidity + '%');
    }
  }
}

main();

Debugging

To enable console debug messages, pass true to query():

let ws3000 = require('ambientweather-ws3000');
let sensors = await ws3000.query(true);

This turns on debug messages for libusb and prints all data sent or received from the WS-3000.

Installation on Raspbian (Raspberry Pi)

You will need the build-essential, git, libusb-dev and libudev-dev packages.

sudo apt-get install build-essential git libusb-dev libudev-dev nodejs npm

To connect to the USB port as the pi user, create /etc/udev/rules.d/50-stmicro.rules with these contents:

ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5750", SUBSYSTEMS=="usb", ACTION=="add", MODE="0666", GROUP="plugdev"

Raspbian Stretch

The node-usb driver currently requires NodeJS v10 which is unavailable on Raspbian Stretch.

$ cat /etc/debian_version 9.13 $ node -v v8.11.1

You will need to upgrade to Raspbian Buster.

$ cat /etc/debian_version 10.9 $ node -v v10.24.0
