MONITORING TEMPERATURE AND HUMIDITY IN A GREENHOUSE

This paper presents a method for monitoring temperature and humidity in a greenhouse using the Arduino Uno motherboard and the DHT 11 temperature and humidity sensor. Automatic temperature and humidity monitoring systems are based on applications dedicated to measuring degrees in a room and bringing them to a set temperature as well as calculating its humidity percentage. To measure and monitor environmental variables, temperature and humidity, a command and control system was proposed consisting of an enclosure equipped with a heating and ventilation device, the Arduino Uno development board and the DHT 11 temperature and humidity sensor. For the software design of the temperature and humidity monitoring station, the open-source Arduino development environment (IDE) was used, which facilitates writing code and loading it into the Arduino Uno motherboard microcontroller.
