Sensor for measuring Sparkfun soil moisture

The FC-28 sensor is used in automatic irrigation systems, IoT projects, and educational experiments involving soil moisture measurement. It enables accurate monitoring of crop conditions and optimizes water consumption

Sensor dedicated to the measurement of nitrogen content in the soil. Allows you to monitor and analyze the level of the element in the soil, and thus optimize fertilization and improve cultivation processes

Capacitive soil moisture sensor with analog output. The board is equipped with a Grove connector and communicates via a analog interface. Seeed Studio 101020614

The soil moisture sensor with comparator LM393 has an analogue and digital output (with adjustable switching threshold). modHUM

A simple and practical soil moisture sensor designed to work with the BBC micro:bit. Using conductive probes inserted into the ground, the module measures moisture levels and generates an analog signal read by the micro:bit. Powered by 3V, it ensures easy and reliable integration, and when combined with the Mi:Power board, it can also trigger an audible alarm when the soil is dry. Kitronik 5647
