EspOledTemp is a little hardware device that I have built and designed myself. The goal has been to create a showcase for my knowledge in mainly electronics and programming.
The base for this build is a NodeMCU, a Soc based on ESP8266. It has a sensor for temperature and humidity connected, a HTU21D module. It also have an OLED connected for showing measured values, these values are also sent via Mqtt to a Mqtt-broker. The values are also presented via a dynamic webpage where you can see the values in near realtime.
The values sent via Mqtt is also used by other software, for example I built an Windows WPF application that shows the same values as the Oled.
