  After the firmware 1q84.tvemasterf35ac96 this code started working with failures, problem only with DHT module.
  In firmware 1v84.tvemaster363580f everything worked well.
  ESP-12q

  var dht = require("DHT22").connect(D4);
  
  var ds18 = require("DS18B20").connect(new OneWire(D5));
  
  I2C1.setup({sda:D12, scl:D14});
  var tsl = require('TSL2561').connect(I2C1);
  tsl.init(tsl.config.address.FLOAT,
           tsl.config.timing._402MS,
           tsl.config.gain._1X);
  
  var a = setInterval(function (){
    dht.read(function (a) { console.log("Temp is      ",a.temp,"  °C and RH is ",a.rh,"%");});
  
    ds18.getTemp(function (temp) { console.log("Temp is      ",temp,"°C");}, true);
  
    tsl.getLuminosity( tsl.config.spectrum.VISIBLE, 
         function (x) { print ("Luminosity is",x,"Lux"); }  
    );
  }, 3000);

  Here's my modified @hygy code. I set Timeout depending on Thermometer Resolution and Max Conversion Time. Tested on DS18B20 and ESP-12q. Can someone check and update code DS18B20.js ?

  /*
  Module for the DS18B20 temperature sensor
  
  var ow = new OneWire(A1);
  var sensor = require("DS18B20").connect(ow);
  sensor.getTemp(function (temp) {    console.log("Temp is "+temp+"°C");  }, true);
  sensor.setRes(9);
  sensor.getTemp(function (temp) {    console.log("Temp is "+temp+"°C");  }, true);
  var sensor2 = require("DS18B20").connect(ow, 1);
  var sensor3 = require("DS18B20").connect(ow, -8358680895374756824);
