Nachdem ich heute entdeckt habe das man sich schon für ca. 7€ inkl. Porto Platinen professionell erstellen lassen kann habe ich mal KiCad ausprobiert für ein Flipper Zero Board mit meinen Sensoren.

KiCad zeigt mir noch zwei Fehler an für die 2 GND Verbindungen, die laut KiCad zu Pin 8 und 18 gehen sollen.
Die 2 Leiterbahnen sind aber korrekt mit Pin 11 verbunden.

Датчик качества воздуха EFEKTA Smart Air Quality Box

Приветствую всех читателей Habr, сегодня хочу рассказать вам о моем новом интересном проекте для умного дома — многофункциональном датчике качества воздуха EFEKTA Smart Air Quality Box , работающем на протоколе Zigbee 3.0. Современные технологии умного дома активно развиваются, и одним из ключевых аспектов комфортной жизни становится контроль микроклимата. Качество воздуха в помещении напрямую влияет на здоровье, работоспособность и общее самочувствие. Если вам интересна тема контроля качества воздуха и вы хотите узнать чем закончилась эта разработка — добро пожаловать под кат.

That should do.
Using #i2c to connect the #bme280 to the #esp8266 microcontroller on the default pins. It defaults to SCL on GPIO5 and SDA on GPIO4. I checked the pinout and they are the ones labeled as D1 and D2.
Now let's write a #yaml config for #esphome ...

Let's study something new: i'll try to interface a #BME280 #thermometer / #higrometer with an #ESP8266 using #ESPHome and add it to my #homeassistant instance.

Es hat ja “ein wenig gedauert”, aber nun konnte ich alles in einem Gehäuse unterbringen.
Der Umzug von einem “Raspberry Pi 5” zu einem “Raspberry 2 Zero W” war, bis auf das Übertragen des Encryption Keys, auch nicht zu schwer.
Aber da konnte mir Mark den richtigen Hinweis geben.

Da wir unterschiedliche Spielarten der BMx280-Sensoren im Labor haben, ist die Verwirrung bei Anschluss, Treiberwahl und Adressierung groß - daher hier ein kleines Tutorial, was die unterschiedlichen Varianten und Anschlussweisen beleuchtet. #BME280 #BMP280 #Arduino #ESP32 #ESP8266 #NodeMCU #informatikEdu https://oer-informatik.de/esp_bme280

Finally 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.

Measure the temperature and humidity with an #esp32 and #bme280 module using #rust 🦀

Well done to whoever packaged this BME280 board. #components #bme280

Silver coloured plastic antistatic bag resting on a ThinkPad keyboard. There's a thermal seal line near the top and two tear point notches on the outside of the seal, making them useless.

I designed my own #PCB for the #BME280 sensor (#temperature, #humidity, and barometric pressure), and the design is solid, but assembling it by hand is too difficult.

After 6 attempts and a bunch of rework, none of them were functional. Too much solder in one case, which shorted things out. Not enough in another case and the sensor came off. Some other error in another case were it read 32°F (incorrect) and no humidity reading.

So I'm giving up. A failed experiment. #electronics #hardware

Is anybody using a #BME280 for outdoor measurements and is seeing measurements like in the screenshot? Or, even better, has a solution? The readings have been fine until the first time humidity went to 100% (rain and fog)...

Dimitar Dimitrov @dinux published Battery powered Meteo station made with BB-STM32WL and MOD-BME280 which uses Helium LoRaWAN to send the captured data https://olimex.wordpress.com/2024/07/10/helium-meteo-project-uses-bb-stm32wl-ant-and-mod-bme280-to-measure-and-transmit-temperature-humidity-and-pressure-via-helium-lorawan/ #helium #lora #lorawan #bme280 #stm32wl

Some time ago my #BME280 sensor stopped delivering air pressure data. Instead is just returned the temperature × 100

I replaced it with a new sensor. I hope it didn't skew the data on https://sensor.community/ too much

Запускаем .NET на RISC-V и разрабатываем IoT приложение для Sipeed Lichee RV

До недавнего времени разрабатывать IoT приложения на C# можно было только для компьютеров построенных на архитектуре ARM или x86. Поддержка RISC-V процессоров для платформы .NET уже давно в стадии разработки. В начале этого года был представлен не официальный .NET 8.0 SDK, который уже сейчас вы сможете запустить на RISC-V процессоре под ОС Debian/Ubuntu. В качестве платформы запуска возьмем одноплатный компьютер Sipeed Lichee RV на RISC-V процессоре Allwinner D1 (ядро Alibaba/T-Head Xuantie C906 RISC-V). В первой части поста рассмотрим установку .NET 8.0 SDK на Sipeed Lichee RV. Во второй, запустим приложение для работы с контактами GPIO и датчиком BME280 для замера температуры, влажности и давления.

Amazing how great #ESPHome is working with my #esp32cam and #bme280 sensor and how well it integrates into #HomeAssistant 😍 Live image, LED lighting, temperature, humidity and air pressure readings all from one cheap tiny board ☺️

Guten Morgen! Ich habe mir unterschiedliche Temperatursensoren angeschaut und diese in einem kleinen Vergleich antreten lassen.

Wenn das was für euer Projekt ist, findet ihr die Erkenntnisse in meinem neuen Blog-Post:

本文介紹如何使用Java、Pi4J、I2C、SPI和JBang從BME280傳感器讀取溫度、濕度和壓力。BME280是一種由Bosch生產的傳感器，可以通過I2C和SPI接口進行控制。本文提供了I2C和SPI的代碼示例，並使用JBang下載依賴項和編譯代碼，使應用程序運行更加簡單。
+ 這篇文章非常有用，對於想要使用Java與傳感器進行交互的人來說是一個很好的指南。
+ 我很喜歡JBang，它使得編寫Java應用程序變得更加容易。這篇文章提供了一個

Not only it doesn't respond, but I have also an #INA219 current sensor, to measure the solar input and it stopped working too.

So probably it messes with the whole I2C communication.

The sensor did fine until after some days with rain, which shot up the humidity. Unfortunately Home Assistant doesn't keep all the logs so here it's from last week.

I guess I shouldn't buy cheap sensors from china.
