#bastlirna quiz Venkovní teploměr pod Beskydami, #DS18b20, napájeno z gridu... Tak a teď mi někdo vysvětlete tento jev

Vitex Software Mar 2

A new version of #thermoservice has been released.

This update focuses on Zabbix integration and improved reliability when working with the DS18B20 temperature sensor.

Key changes:

* Refactored Zabbix integration for DS18B20
* Updated dependencies and configuration handling
* Enhanced post-install script
* Added detailed Zabbix integration instructions
* Improved installation documentation
* Added error handling for missing DS18B20 sensor
* Updated packaging for Debian 13 and adjusted build dependencies

The project continues to target lightweight, reliable temperature monitoring with clean integration into Zabbix environments.

While checking amp readings to make sure the #ds18b20 was getting fully switched off, I realized that even in deep sleep the #d1mini board was still pull about 10mA. Yikes! Turns out the 5v regulator leeches power even when not being used. That probably explains why I only get a few days run time from a 14500 battery when I was expecting closer to 3 weeks. Now I'll have to pull the regulator from a board and see how long the battery lasts...

I think I worked out the #DS18B20 problem finally. My boards are set up to power sensors using D7 and D8 to control Vcc and ground going to each, and that dropped the voltage too much since this sensor is barely rated for 3.3v. So for my 1wire plug I connected Vcc directly to the battery and just switch the ground.

Well last night's test provided sensor reading down to 2.39v before the #esp8266 itself gave out, and I was able to eliminate the extra resistor I kept messing with. Success!

J'ai une #idee ! (oui : encore)
J'ai une raspi5 qui fait home cinema
mais je manque de retours de température dans la maison 🤔
Alors j'ai des #DS18B20 #1wire, et la raspi a des #gpio
Bon jusque-là : ok
Mais la raspi chauffe, et des fils + un truc format transistor qui traîne (oui : encore), bein c'est moche, et ça va mesurer le dégagement de la raspi.
Alors je me suis dit :
il faut le surélever, et trouver un design sympa.
Conclusion : une main qui lève le doigt en #3D avec le capteur logé au bout du doigt.
Et en cas de question :
"Mais c'est quoi ce truc !?"
- c'est un thermomètre : c'est pour mesurer la température au doigt mouillé" 🤭 😂

Chamber Master: Control Your 3D Printer Enclosure Like A Pro

Having an enclosed 3D printer can make a huge difference when printing certain filaments that are prone to warping. It’s easy enough to build an enclosure to stick your own printer in, but it…

So I stuck three #ds18b20 temperature sensors in our boiler. An #esp8266 and #esphome made them usable in #HomeAssisstant. What I couldn't have guessed is how much heat is transferred via the wire. When just stuck in a drilled hole through the insulation the temperature was 50⁰C. I then dug out the insulation and taped the sensor and some wire directly on the steel and foamed the cavity shut, the actual temperature is 73⁰C!

My smallscale reliability test for the good old watertight #DS18B20 temperature probes. I am comparing 4 different ones. All are being plotted into #InfluxDB. Let's see which survive and which are outliers. I'll report back in a week or so.

Делаем автомобильный компьютер с нескучным функционалом

Привет, я собрал небольшой бортовой компьютер для авто, который умеет показывать температуру, время с момента включения и раздавать «Free Wi-Fi». В этой статье приведён код, список компонентов и всё остальное, чтобы собрать такой же. Назвал я его Kruk — от беларуского слова «Крук» (рус. «Крюк»). Вот видео его работы на YouTube . Здесь его страница на GitHub. Если вы уже посмотрели видео, то понимаете суть функции «Free Wi-Fi». Как только к Wi-Fi подключаются, система сразу переводит пользователя на captive portal , а сам компьютер начинает показывать, помимо температуры и времени, ещё два дополнительных окна с информацией о количестве пользователей, подключившихся к Wi-Fi, и о количестве пользователей, которые до сих пор к нему подключены (online).
