Frequently Asked Questions (FAQ)

  • Q: How do I connect a DS18B20 with Arduino?

    A: I'm going to show you how to use DS18B20 digital temperature sensor with Arduino, so you can measure the temperature of the air, liquids like water and the temperature of the ground. more

  • Q: Where can I find a DS18B20 Arduino library download?

    A: In this protip, I will show you how to build DS18B20 Digital Thermometer with Arduino. more

  • Q: Where can I find the DS18B20 library download?

    A: Arduino Library for Maxim Temperature Integrated Circuits.You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The centre pin is the data line '1-wire'. more

  • Q: Where can I find the DS18B20 NodeMCU library?

    A: This module provides access to the DS18B20 1-Wire digital thermometer. Note that NodeMCU offers both a C module (this one) and a Lua module for this sensor. more

  • Q: How do I use a pull-up resistor for the DS18B20 sensor?

    A: If you were banking on your stockpiles of 4.7K ohm resistors to be the one reliable store of value in these uncertain times, you need to rethink your long-term asset preservation strategy because the decade-long run of stable demand for this part is about to plummet. Yes – it is now possible to connect DS18B20 sensors without any external pull-up resistor at all! more

  • Q: How do I connect a DS18B20 to a Raspberry Pi?

    A: The DS18B20 "1-wire" sensors can be connected in parallel - unlike nearly any other sensor sold! All sensors should share the same pins, but you only need one 4.7K resistor for all of them. more

  • Q: How do I use Python with the DS18B20 sensor?

    A: For the following code to work you need to have at least one DS18B20 temperature sensor with its data line connected to GPIO12. You must also power the sensors and connect a 4.7k Ohm resistor between the data pin and the power pin. more

  • Q: Is there a waterproof DS18B20 sensor?

    A: This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. more

  • Q: Where can I find a DS18B20 wiring schematic?

    A: The digital DS18B20 Sensor provide fairly good accuracy and range of connection. The wire length can be reach up to 100m. The DS18B20 has four main data connection. more

  • Q: Where can I buy DS18B20 waterproof temperature sensors?

    A: This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor. more

  • Q: Where can I find the resistors scheme for the DS18B20 temperature sensor?

    A: For complicated or long wire lines, if it is necessary, there are two variants for compensation as shown on the figure below: First one: To connect parallel resistor 4.7k between +5V and 1W pin of 3pin plug-in (variant 1 of the scheme).Second one:To make RC filter like it's shown at variant 2 of the scheme.You can try with 470pf and 62 or 100 Ohms resistor.You can try variant 1 first, if there's no success - variant 2.You can combine variant 1 and 2 but connect parallel resistor before RC filter. more

  • Q: How do I set up a DS18B20 and ESP8266 connection?

    A: In this tutorial we will show how to build DS18B20 and ESP8266 temperature sensor without Arduino. We will use Arduino IDE and report temperature over WiFi on EasyIoT server. more
