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. The developing of low-cost sensors involves adequate materials and simple manufacturing methods, ensuring reliable and accurate measurements. Embrapa Instrumentation's has been putting efforts for the low-cost agricultural sensor’s development. This article discusses a sensor for soil moisture measurement using the microwave technique; a sensor for measuring the apparent electrical conductivity of soils; a sensor for measuring water and plant relationships; and a sensor for evaluating spray solution concentration to weeds control to improve crop yield and reduce the use of water. Such affordable sensors in agriculture can provide an effective and sustainable solution to enhance productivity into small and medium farms, as well as increasing in food security and supporting sustainable agriculture.
