E-paper Arduino термометр на ESP-IDF
Наверное каждый любитель электроники имеет в запасе модули приобретенные на всякий случай. Так несколько лет назад я не смог пройти мимо 1.5 дюймового E-Ink дисплея, лежащего на витрине радиомагазина. Через некоторое время нашлось для него применение. В статье ESP32 E-Paper Thermometer описывается, как отображать окружающую температуру, измеренную с помощью датчика DS18B20. Проект выполнен в Arduino IDE. Но я решил пройти "Путь самурая" и портировать код на ESP-IDF. Пришлось немного повозится с библиотеками для работы с дисплеем. На этом мой путь не окончился, как говорят: "У самурая нет цели, есть только путь". И я решил, что было бы неплохо добавить еще несколько сенсоров, измеряющих влажность, давление, CO2, а потом отправлять эти данные по MQTT. В том же радиомагазине был приобретен фанерный домик-конструктор со светодиодным ночником. А в другом магазине - модуль с датчиками. Таким образом родилась идея сконструировать Micro-smart-home. На передней части домика расположен дисплей на пластиковых стойках. А с другой стороны расположен модуль с сенсорами.

Of course its time to add some sensors to my #glassHouse / #coldFrame - I've built a wireless sensor (uses an old 868Mhz sensor network I have at home) and finally got round to writing a ds18b20 driver for it (https://git.solarcene.community/smallsolar/ukhasnet_ds18bs20).
It will have 2 temperature sensors - one will be installed 'outside' the frame while the other will be inside - but I'm not sure where - any thoughts?

Solarcene GiteaFinally had some fun with my Arduino Uno R4 WiFi that I bought to learn some of this stuff and make an environment analyzer.
#ChatGPT wrote the code, I soldered and connected sensors - modern day teamwork .
Had to find my old DS18B20 for temp reading because temperature sensors got way too hot on both BME280 and AHT21.

Wo hast Du denn den #mhz19 gekauft?
Es sind immer mehr gefälschte #Elektronik Baueile auf dem Markt.
Oft wird das nicht mal wie beim #DS18B20 erkannt.
Aus dem Grund kaufe ich nur noch bei renommierten Elektronik Händlern wobei da der blaue Claus natürlich raus ist

Diesmal mit den Erkenntnissen, dass es einen riesigen Markt mit Fake-Versionen des #DS18B20 gibt, dass die Liste aller deutschen Worte (inkl. Varianten durch Flexion usw.) über 1,9 Millionen Einträge hat (und wofür man diese Liste einsetzen kann) und warum „Weiße Weihnachten“ (was eine bescheuerte Phrase BTW) hier in der Region so selten sind. Außerdem gibt es einem Mini-#Jahresrückblick (den großen braucht ihr nicht, weil ich euch ja schon wöchentlich füttere).

www.marcusjaschen.deI ended up programming this one with Adafruit's #circuitpython, because they have a very easy to use #ds18b20 driver and wifi driver. My preferred #Rust framework, #embassy, doesn't yet have a 1wire implementation and it looked a little gross to write it for a one-off temp sensor. I'll return to this some time later; for now, I have a thermometer located near my thermostat that I can poke and get a reading from whenever I want.
Also: The pi pico is a power hog but dang is it handy.
Hi everyone, in this video I connected a digital temperature sensor (DS18B20) to Commodore 64 and did some non-scientific measurements :) To make this work, I implemented a 1-wire protocol in the assembly. Enjoy :)

I found an interesting alternative to #DS18B20, the MAX31820.
It seems to be a 3.3V version of the DS18B20, which should work fine with the #ESP32 I'm using.
It is also cheaper and in stock at DigiKey. I'm going to give it a try

For those of you that want to know if the DS18B20s you have are the real ones or the fake , there is very good information about the differences at https://github.com/cpetrich/counterfeit_DS18B20

GitHubSo, I searched on DigiKey for real DS18B20s to include on my next order... and what a surprise!
Almost all variants of the Maxim DS18B20 are out of stock (as expected), but they are now selling those chinese clones at almost the same price as the authentic ones!

Crazy world. That seems to be how the supply chains are working in 2023.

Today I'm going down the rabbit hole of DS18B20 chip fakes .
A quick test of a batch of fakes I bought here in Argentina (because those seem to be the only ones you can buy on the local market) revealed that they measure about -2 C with respect to a real Maxim DS18B20. What a .
I trust the Maxim one because it is within 0.2 C of some Sensirion sensors I have here.
I've had temperature sensors at home for years, in each room, based on #ESP8266 + a sensor (#DHT11, or #DS18B20 - depends).
One of the issues has always been calibration. It's burdensome to have to adjust the code of each individual sensor with calibration data + it can change after months.
Today, I've set up a simple web server with a #REST api I can use to set #calibration data. The web server is on at power up. Once I've calibrated I can disable it and just post temperature via #MQTT.
