Proceedings... Wilmington, USA: IARIAc2023  a8 - 15  aAbstract Agricultural sensors are crucial in improving crop yields and reducing resource waste. It has led researchers to develop affordable sensors that can be easily integrated into existing farming systems. Developing inexpensive sensors involves using low-cost materials and simple manufacturing methods, ensuring reliable and accurate measurements. One of Embrapa Instrumentation's objectives is the research and development of sensors applied to agriculture. This article briefly discusses a sensor for soil moisture measurement using the microwave technique; a system for measuring the apparent electrical conductivity of soils; a Sensor for measuring water and plant relationships; and the Sensor for evaluating spray solution concentration to control weeds to improve crop yield and reduce water. Using affordable sensors in agriculture can provide an effective and sustainable solution to enhance the productivity of small and medium farms, thus increasing food security and supporting sustainable agriculture.  aAffordable sensors  aSoil moisture  aSoil resistance  aSpray quality  aWater-plant measuring1 aRABELLO, L.
