ESP32 E-Paper Thermometer with a DS18B20 Sensor

Our friends on educ8s.tv published a new video. Check it out.

In this ESP32 project video, we are going to use an E-Paper display and a DS18B20 temperature sensor to build a low-power thermometer. We are going to use the Arduino IDE to program to ESP32 board. ! It is a very easy project to build. It won’t take us more than 5 minutes so let’s get started!

3 in 1 Temperature Sensor Shield For Arduino Nano

This 3 in 1  shield for Arduino Nano helps to develop various temperature measuring applications. Arduino Nano shield consists of 3 different types of temperature sensors.

  1. MLX90614 non-contact temperature sensor
  2. 10K NTC Analogue Temperature Sensor
  3. Programmable Resolution 1-Wire Digital Thermometer

With this board is easy to make a contactless temperature meter using the earlier published 4 Digit display Nano shield,

Note : Only MLX90614 sensor can be used with display shield , DS18200 and NTC has to be removed as display uses those port pins.

DS18B20 Sensor Based Thermometer with Nokia 5110 LCD display

Hi guys welcome to this tutorial. Today we will be building a simple temperature monitor using the DS18B20 sensor with a Nokia 5110 LCD Display and an Arduino mega.

The DS18B20 digital temperature sensor gives a 9-bit to 12-bit Celsius temperature readings and also has an alarm function with nonvolatile user-programmable upper and lower trigger points. The sensor communicates via the 1-Wire communication protocol and thus by definition requires only one data line (and ground) for communication with a central microprocessor. Among the special features of this sensor, is an operational mode in which it can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply line.

Arduino Analog Thermometer With DS18b20 Module

Sometimes, it is necessary to add a temperature indicator into your projects. Therefore, in this tutorial you will learn how to hack your analog Voltmeter and convert into an analog Thermometer using Arduino and a DS18B20 temperature sensor.

Temperature Controlled Fan With LED Status

This is a simple fan controller with single LED temperature status light using an ATtiny85 microcontroller and DS18B20 temperature sensor. The fan is turned on/off based on temperature sensed and the controller goes in sleep mode when the temperature drop below a predefined threshold.

Simple ATtiny85 fan controller to turn a fan on/off based on temperature. Includes an LED as a temperature indicator. LED is dim at start of fan on temperature and blinks when above a max temperature. Fan is not PWM controlled since I am using a small 5V fan which is quiet running at 100%. The controller is in sleep state while the temperature is below the minimum threshold and wakes up every ~8 seconds to recheck the temperature. When temperature is above minimum threshold, the controller will stay awake checking every second till the temperature falls below the minimum threshold. The code uses ds18b20 library by Davide Gironi.

How to make an analog Thermometer with Arduino a DS18B20 and an analog Voltmeter

In this Arduino Tutorial educ8s.tv is going to modify this analog Voltmeter and convert into an Analog Thermometer using Arduino and a DS18B20 temperature sensor.

Today we are going to learn how to use this analog voltmeter with Arduino and make it show the temperature instead of the voltage. As you can see, in this modified voltmeter, we can see the temperature in degrees Celsius. The temperature is measured by this digital sensor, a DS18B20 and it is then displayed on the voltmeter. I really like analog dials like this one, because they give a vintage look to the projects. Let’s now see how to achieve that result.

Temperature alarm for boiling milk

image2

Domen Ipavec shares his temperature alarm for boiling milk. Temperature alarm uses an Atmel attiny841 microcontroller, DS18B20 high temperature waterproof temperature sensor from adafruit, 2×16 HD44780 LCD and a buzzer to do its job.

Anyone who has ever boiled milk on the stove knows, that it has a nasty habit of overflowing. That is why I created the temperature alarm for boiling milk to be used my mother. It continuously measures the temperature of the milk and sounds an alarm when the temperature is over the preset alarm value.

ESP8266 temperature logger

phimg_20160301_204007-600

A ESP8266 temperature logger project from Facelesstech:

I decided to use the esp-01 module because I only need 2 GPIO pins since I was using the DS18B20 temp sensor and the WS2812 LED. This made the hardware really cheap and easy to reproduce too. I normally use FTDI boards when it comes to the USB to serial on my projects but I couldn’t find a FTDI board with micro USB that didn’t cost the earth. That’s why I went with the CP2102 which I hadn’t used before.
I think what really made me feel good about this project was the fact that I came up with the idea to use a Full sided male USB port for power teamed with a AMS1117 3.3v voltage regulator. This would allow me to just plug this straight into a USB wall wart or a phone charger battery bank.

AAduino – Arduino Wireless in AA form factor

aaduino-comparison

Johan wanted to shrink his Arduino based ISM radio node to fit in an AA battery compartment so AAduino was born.

The AAduino is an wireless Arduino clone the size of an AA battery with Keystone battery terminals rotated 180° to act as positive and negative terminals. It is powered by an ATMega328p and is fitted with an RFM69C companion. There is room for two DS18B20 temperature sensors and an indicator LED.

ESP8266 + DS18B20 to Emoncms


Jhon_Control @ instructables.com has written a tutorial on how to monitor temperature using the ESP8266 and DS18B20 and display the data on Emoncms platform.  Emoncms is an open source web application that enable you to monitor and visualize different environmental data.
