ESP32, SunDuino – temperature/humidity Si7021 sensor and OLED 128x64px (I2C)
Other article about ESP32. We again connect ESP32 to temperature/humidity sensor Si7021 (HTU21), but today we also connect OLED where will be showed data from sensor. The OLED has 128x64px…
ESP32, SunDuino and temperature/humidity sensor Si7021 (HTU21)
Other article about ESP32, with using of development board of SunDuino ESP32 and temperature/humidity sensor Si7021 (HTU21). I recommend the first article about ESP32 and SunDuino ESP32 which is available…
ESP32 and Arduino IDE
Finally, I can write you a short tutorial how to play with ESP32 (more powerful than ESP8266). On the internet is a lot of tutorials how to do it, but…
ESP12E (NodeMCU, ESP8266) + Si7021
After my experimentes with NodeMCU and SHT75 I designed next version of my mini meteostation. I designed own PCB for plastic box. I chose the same ESP8266 module which is…
NodeMCU (ESP8266, ESP-12) + SHT75 + TMEP.CZ = Arduino meteostation
Everybody has meteostation… somebody better, somebody worse. I wanted meteostation too. I didn’t spend a time with development of sophistic device. My requirements was very easy – measurement temperature, humidity…
