Gravity: Analog Soil Moisture Sensor

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

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

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

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

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

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

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

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.

Module with a soil moisture sensor for the M5Stack sets. It has an analog output and a digital output with adjustable reaction threshold. M5Stack U019

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

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

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