Most house plants require temperature, humidity, and moisture monitoring for optimal care. Temperatures exceeding the optimal range can cause stress, wilting, stunted growth, and even death, while cold temperatures can slow plant development, leading to weak growth and susceptibility to frost damage. Excessive humidity encourages fungal diseases and prevents proper transpiration, while drier air typically…
How to use a DHT sensor to show humidity and temperature values on an OLED display
In Part I and Part II of this series, we learned how to use an analog sensor — including a potentiometer (POT), a light-dependent resistor (LDR), and a soil-moisture sensor — to present values on an organic light-emitting diode (OLED) display. In Part III, we’ll also present data on an OLED display, but this time…
