Producers need to have information on the agricultural parameters of their plantations without having to be on site. The objective of this work is to propose an intelligent agriculture platform or Precision Agriculture (PA) in order to collect soil humidity, air and temperature. The purpose of the PA is to contribute to food security while ensuring optimal use of resources. To do this, we offer a platform consisting of HW-390 capacitive soil humidity sensors, DHT22 air temperature and humidity sensors and microcontrollers. TheHW-390 returns an analog value that gravitates around 1540 when the soil is wet and 3155 when the soil is dry. The DHT22 measures temperature and humidity with an accuracy of +/- 0.5°C and +/- 1% respectively. The power supply circuit consisting of a rechargeable battery in a maximum of 10 hours has an autonomy of 38 hours.
