temperature-stream

Temperature from a Raspberry Pi GPIO as a stream.

Supports DS18B20 sensors.

Usage

const path = require("path")
const fs = require("fs")

const tsr = require("temperature-stream")

const rootDir = "/sys/bus/w1/devices/"

const files = fs.readdirSync(rootDir)
const dir = files.filter((el) => {
  return /^28/.test(el)
})[0]

fs.createReadStream(`/sys/bus/w1/devices/${dir}/w1_slave`)
  .pipe(tsr())
  .pipe(process.stdout)

Adding a semicolon to the end of the resulting data:

var fs = require("fs")
var tsr = require("temperature-stream")

var target = fs.createWriteStream(tempdir + "/temp.txt")
fs.createReadStream("/sys/bus/w1/devices/10-000802824e58/w1-slave")
    .pipe(tsr(";"))
    .pipe(target) // 22750;
