A robust sensor for approximate measurement of nitrogen, phosphorus and potassium (NPK) levels in soil, ideal for precision farming and field applications. With a rugged design (IP68), RS485 MODBUS-RTU communication and a wide power supply range, it allows easy integration with Arduino-type systems and operation in harsh environmental conditions. DFRobot SEN0605

Soil moisture sensor with analog output. It has a probe with pointed tips, which allows you to easily place it in the ground. The analog output voltage level increases in proportion to the humidity level

Crowtail-Capacitive Moisture V2.0 is a durable soil-moisture sensor based on capacitive technology, ideal for monitoring plant hydration levels. Intended for use in projects with 3.3–5 V microcontrollers.

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
