Soil Moisture Sensor - Waveshare 9527

Capacitive soil moisture sensor with pump for M5Stack sets, equipped with holes compatible with LEGO. M5Stack U101

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

Soil moisture sensor with analog output. The probe has two pointed tabs, making it easy to insert into the ground. It is supplied with the voltage of 3.3V or 5V. DFRobot SEN0114

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

Seeed Studio 101990982 is a professional RS485 soil sensor that enables simultaneous measurement of moisture, temperature, and electrical conductivity at four different depths. With its robust design and IP68 protection, it is suitable for long-term applications in agriculture, greenhouses, and environmental monitoring, providing reliable data for irrigation and crop optimization.

Resistive soil moisture sensor. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020008

Soil moisture sensor with analogue output. It has a shape resembling a fork, which makes it easy to put it in the ground. The voltage level of the analog output increases in proportion to the ground moisture level. The sensor can be used in an automatic watering system. Version with a 3.5 mm ARK connector. SEN-13637

This soil moisture sensor uses a resistive measurement between two gold-plated probes. Corrosion resistance ensures long life and stable measurements. It works with the micro:bit and Arduino platforms, allowing for reading soil moisture levels as an analog signal. Adafruit 6362

Capacitive soil humidity sensor with I2C interface powered by 3-5V. Adafruit 4026

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.

Waterproof soil moisture sensor with analog output. The probe has a pointed tip, which allows it to be easily inserted into the ground. It is supplied with the voltage from 3.3V to 5.5V. DFRobot SEN0308

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

Capacitive soil moisture sensor with analog output (Grove connector). The probe has a pointed tip, which allows it to be easily inserted into the ground. Cytron MAKER-SOIL-MOISTURE

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

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