FC-28 soil moisture sensor (Funduino)

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

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

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

A set of three capacitive soil moisture sensors for a home automatic irrigation system. Pimoroni PIM520

Soil moisture sensor dedicated to micro:bit. It is supplied with the voltage from 3.3 V to 5 V and communicates via an analog signal. SparkFun SEN-15272

Kit for controlling soil moisture of cultivated plants. It contains the HAT Mini module and soil moisture sensors. Pimoroni PIM510

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.

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

Soil moisture sensor based on soil resistivity meansurement

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

A moisture sensor specially adapted to work with the Kitronik Greenhouse Kit for the BBC micro:bit. It allows monitoring of moisture in the soil. It can be programmed using any editor for the micro:bit. Kitronik 56107

Earth humidity sensor with analogue output, supplied with 3.3 to 5.5 V voltage with Gravity connector. DFRobot SEN0193

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

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
