How to measure temperature very accurately with an Arduino

FAC1FAZIO6E5XYH.MEDIUM

This project shows how to measure temperature data from a TSYS01 Temperature Sensor board using Arduino:

While studying in university we were challenged as part of a course work into designing a box with very accurate temperature control. If the project were to succeed, multiple boxes were to be built and used in a research project studying the effect of surface material on the perceived temperature of flooring and other building materials.

LED Weather Forecast using Raspberry Pi

FJFLPYYIN943NGB.MEDIUM

AughtNaughtZero @ instructables.com posted his latest project, a LED matrix visualizing data from a weather website such as temperature, pressure, humidity, wind speed etc.

This project utilizes a 6 x 16 matrix of RGB LEDs to visualize a weather forecast pulled from the Weather Underground API. A Raspberry Pi runs a python program designed to fetch weather forecast data from the API at regular intervals, parse the data into temperature, pressure, humidity, wind speed, chance of precipitation, and weather condition arrays, and then colorize and display that data across the LED matrix.

Temperature Display with NeoPixel Ring Color

3637311436166764209

This is an OLED temperature display based on ATmega328p along with a NeoPixel led ring to display different colors depending on temperature.

This is a small temperature display using a OLED with a NeoPixel Ring around it using MQTT on a ESP8266 and sending data to the on board ATmega328p. It will cycle on a timer though environmental data from other nodes in the house. The LEDs represents the temperature based on color to give an idea of the temperature in the home or apartment I also added a PIR to turn off the LEDs when no one is around since this is designed to run off a LiPo battery. The core is running DomotiGA (Home automation core) and Mosquitto (MQTT broker). Part of this project is exploring the ESP8266 and learning MQTT.

Using BMP180 for temperature, pressure and altitude measurements

BMP180_11

Raj from Embedded Lab has posted a comprehensive tutorial on how to use BMP180 for temperature, pressure, and altitude measurements.

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings.

Temperature controlled fan

20160409_FanController_020-600

Lukas Fassler from Soldernerd has written up documentation on his DIY fan controller project:

I’m currently mainly working on my new anemometer design but once in a while I get distracted. For example when my Keysight E3645A lab power supply was making so much noise that I could hardly concentrate. That’s when the idea of this fan controller was born.

‘Circuit Cobbling’ the Riffle Data Logger

medium_completed_board

John Keefe has designed an open source data logger that is able to monitor conductivity, temperature and turbidity of water in lakes and fits inside a plastic bottle.

The board is designed to monitor the conductivity (and, possibly, contamination) of water in lakes and streams, with the wonderful feature that it fits through the mouth of a regular water bottle. It’s called Riffle and it is the brainchild of Don Blair, who’s working with Public Lab and the MIT Center for Civic Media. This week I had the honor of working with Don at MIT.

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.

Wifi Home Thermostat

thermostat

asheville makers @ instructables.com has posted a Wifi enabled thermostat that can be programmed via a touch screen display or via the internet.

This Instructable explains about how I built WiFi enabled thermostats for my home. The thermostats are programmable with 6 different time periods during the day, although increasing that to any arbitrary number would be fairly trivial.

The world’s tiniest temperature sensor is powered by radio waves

Researchers at the Eindhoven University of Technology in the Netherlands have created what they call the tiniest temperature sensor that is powered by the same wireless network it uses to communicate data. The sensor measures 2 square millimeters and needs no physical connection to send data. The current version of the sensor has a range of 2.5 centimeters but this is something to be improved in future versions.

The sensor contains an antenna that captures the energy from the router. The sensor stores that energy and, once there is enough, the sensor switches on, measures the temperature and sends a signal to the router. This signal has a slightly distinctive frequency, depending on the temperature measured. The router can deduce the temperature from this distinctive frequency.
