Description TheGrove - Moisture Sensor can be used to detect the moisture of soil, to judge if there is dampness around the sensor. It can be used to decide if the plants in a garden need watering. It can be used in gardens to automate watering plants. It can be used very easily by just inserting the sensor into the soil and reading the output using ADC. Note This sensor is not hardened against contamination or exposure of the control circuitry to water and may be prone to electrolytic corrosion across the probes , please use it for PROTOTYPING ONLY. Features - Grove compatible interface - Easy to use Specification - Operating voltage: 3.3~5V - Operating current: 35mA - Sensor Output Value in dry soil: 0~ 300 - Sensor Output Value in humid soil: 300~700 - Sensor Output Value in water: 700 ~ 950 - PCB size: 2.0cm X 6.0cm For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product. https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2017-08-05 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2018-01-25 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2021-05-21 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2021-09-28 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2022-01-07 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2023-02-25 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2023-04-18 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2023-09-29 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2025-02-08 https://elecena.pl/product/9696426/101020008-arduino-grove-humidity-sensor 2026-02-20
