This article considers the selection of sensors used for measuring and controlling temperature and humidity in smart greenhouses, as well as their application based on the Arduino platform. The main criteria for sensor selection include measurement range, accuracy, installation location, signal transmission distance, and operating conditions. The study analyzes the applicability of thermocouples, resistance temperature detectors, the DS18B20 digital sensor, and DHT11 and DHT22 temperature-humidity sensors. The processes of receiving, processing, and monitoring sensor data using Arduino are discussed. In addition, temperature control methods are compared in the Matlab Simulink environment in terms of accuracy, stability, energy consumption, and response time. The main purpose of the article is to determine an optimal sensor and control approach for reliable measurement and control of temperature and humidity in smart greenhouse conditions.
