So, I connected all the sensors on NodeMCU and displayed their data on a 16x2 LCD. In the video below I used lighter on temperature sensor DS18B20 and the effect can be seen on LCD, as the temperature rises from 30 °C to 35 °C. Later I test the LDR sensor by blocking the light and the result can be observed on LCD.
