Combined WiFi sensor for temperature and moisture of soil

Physical parameters, such as temperature and moisture of soil, are important indicators in agriculture. The current study focuses on the development and assembly of an autonomous sensor for soil moisture and temperature through the use of a standard Arduino d1 mini module, equipped with a capacitive humidity sensor. The developed sensor configuration is distinguished with the possibility to transmit data via WiFi communication network and renewable energy system with photovoltaic power panel, which allows the results to be transmitted wirelessly and the sensor to operate autonomously powered by solar energy.
