Hacking home weather station transmitter

IMG_2378

Bob hacked a home weather station transmitter and made a home thermometer from it. He writes:

Recently I’ve found this piece of electronic on the dumpster, it was looking interesting – compact case with battery holder, LCD display, temperature and humidity sensor. It has also radio transmitter, but I’m not interested in it since I don’t have the receiver station. I decided to bring it back to life.

Nixie thermometer

nixie-60

Luca Dentella has build a Nixie thermometer to measure the temperature of the liquid cooling system, file are available on Github.

I decided to log the design and the development of the project in ten blog posts. They show my “divide et impera” approach: I divided the whole project in small tasks (drive a nixie with Arduino, read the temperature from a thermistor, use an rgb led module, prepare the first prototype on a perfboard, design the pcb, assembly the final product), all described on my blog with examples and videos.

Quick Arduino Hygrometer with OLED display

F8FMZUCIKA08IN2.LARGE

jazzycamel @ instructables.com has published an Arduino based Hydrometer with OLED display. It uses an Arduino Leonardo Pro Micro, an Adafruit SSD1306 OLED display and DHT11 digital temperature and humidity sensor.

We have been having some condensation and mould issues in our apartment recently due to, I think, the humidity levels. Our property is relatively newly built and, as such, has very good insulation properties (double glazed windows etc.).

Arduino OLED Thermometer And Hygrometer With DHT11

F3KNHZSIFO75QNW.MEDIUM

KonstantinDimitrov @ instructables.com has build a Arduino based OLED Thermometer and Hydrometer using DHT11 sensor.

Hello, everyone ! Today I am going to show you how to make Arduino OLED thermometer and hygrometer* with DHT11.

The OLED we will use today is .96″ inch in size, features 128×64 pixels and uses the SPI Bus.

We will use the u8glib library to communicate with our display. This library has many available parameters(download it and unzip it at /Program Files(x86)/Arduino/Libraries).

Contactless Infrared Thermometer (Pyrometer) using MLX90614 and MSP430

photo3

mcs.uwsuper.edu has build a contactless thermometer based on MLX90614 sensor and MSP430 mcu.

The device is designed for contactless measuring and monitoring temperature of objects. It is built on Melexis MLX90614 sensor and can measure temperatures in the range from -70°C to +380°C with 0.5°C accuracy and 0.01°C resolution. The period of measurements can be set in the menu from 1 sec to 1 min in 10 sec increments. It is also possible to record the temp measurements and upload them to a computer via the serial interface through X1 and an external level converter.

4 Digit Thermometer using DS18B20 and PIC16F628A

led_thermo

moty22.co.uk has a PIC16F628A based thermometer using DS18B20 digital sensor.

Counter based on PIC16F628A . Included C code and circuit diagram. Displays -55 to 125 centigrade. The temperature is read every 15 seconds, can be changed in the code. The math is using integers to calculate the degrees and the tenths of degrees are calculated separately.
The 7 segment LED is common cathode, 4 separate digits can be used with segments a to g linked.

PC Thermometer Using D-sub Connector

One of the element in medical is the temperature, it prevents the buildup of humidity in the operating room, prevents the doctor and nurse from sweating while operating and refrigeration of medicines. In medical applications, reliability of the components is critical. The TE Connectivity D-sub connector has been accepted by the electronic industries for their rugged design and ease of application.

The circuit is a simple PC thermometer using the 5747840-6, a male D-sub connector of TE connectivity as a way of communication to the computer. The LM2936Z is a 5V regulator that provides input voltage to U1 and U2. The DS1621 (U1) is a digital thermometer and thermostat sensor, which indicates temperature for the device. The other DS1621 (U2) is optional for outside temperature monitor or a second reference source to be monitored. Software is used in the PC so that the temperature can be monitored in the PC’s screen.

The PC thermometer is applicable in situations where the room’s temperature is being monitored at a distance like in the operating room, blood bank, and other hospital applications.

Bluz powered probe thermometer to stream temperature data to your smartphone. Never dry out your steaks or chicken again! By Eric Ely:

With summer arriving, and the fear of dried out chicken looming, we wanted a more high tech way to track the temperature of items we are grilling outside. There are wireless probe thermometers, but they require carrying around a separate readout. We wanted a way to read the termperature from our smartphone, so we took the just the thermometer and hooked it to bluz!

Hello, everyone !!! Today I’m going to show you how to make Arduino thermometer with DS18B20 digital temperature sensor, builded on breadboard and connected together with jumpers.

Info about the sensor – DS18B20 is 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it – allows for a huge number of sensors to be used on one data bus.

89S52 Thermistor Thermometer: LCD version

thermo

by Wichit Sirichote:

This is the 2nd version of Thermistor Thermometer Project done by another group of my student. The 1st version having 4-digit 7-segment LED shows the use of simple display device. For applications that needs text display, this LCD version is more suitable and easy to adapt for many kinds of measuring devices.
