  Thank you! I'll provide a DHT22

  @MaBe thanks for the support.

  But, i want to know if the sensor has more resolution. With toFixed(2) appears .00 and i need por precision to study my data. The question is: DHT11 has this resolution? There are some code that i have to add? Thanks

  I'm using a temperature / humidity sensor (DHT11) like this:

  var dht = require ("DHT11"). connect (C11);
  dht.read (function (a) {console.log ("Temp is" + a.temp.toString () + "and RH is" + a.rh.toString ());});

  However, I wanted a resolution of at least two decimal places. But I only get the whole number ... How should I proceed?

  I am reading a humidity sensor with the espruino and would like to know if it is possible to save this data in excel.

  Thanks to the support, this humidity sensor was developed in my teacher's lab, it is a capacitive circuit board with a conditioning circuit that contains an IC 555. It has a 5V power cable, a ground and an out, whose the values ​​are given in frequency.
  I got satisfactory results with the oscilloscope but the desire to get this data with the espruino.

  I need to read a humidity sensor whose output is given in Hz, but the values ​​are higher than 10KHz and below 20KHz, I would like to know the most appropriate way to do this value measurement with a STM32F4 discovery. All I want is to print the frequency on the IDE console or a hypertherminal.
