## Overview

The Plantmate Capacitive Soil Moisture Sensor is a waterproof, dual-probe sensor designed for precise soil moisture detection. Operating at 3.3V, it’s compatible with low-voltage MCUs like Arduino, featuring an 85cm Micro USB cable and adapter for easy connection. Built with corrosion-resistant materials, it offers long-lasting performance for smart gardening and intelligent agriculture applications.

## Description

Dealing with water or moisture, waterproof is essentially important. The components of the Plantmate Capacitive Soil Moisture Sensor are over-molding, it is waterproof; Plantmate Capacitive Soil Moisture Sensor has the sensor probes on both sides of the PCB, it is more sensitive and accurate;. Plantmate Capacitive Soil Moisture Sensor has a longer cable to connect with your MCU board, cable itself is about 85cm with a Micro USB male end. it comes with a Micro USB female adapter to make it even easier to use. Surely that you can cut off the Micro USB male end to connect with your MCU pins directly.. Plantmate Capacitive Soil Moisture Sensor operates with 3.3V and it is compatible with low-voltage MCUs. To make it compatible with a Raspberry Pi, an ADC converter is required. . Interface : Micro USB. Operating : Voltage3.3 V DC. Output : Voltage3.0 V DC. Cable length : 85 cm. Weight : 32g. Wire Assignments:. Wire Description Red 3.3V DC-input (“VCC” on Micro USB). Gray & White 0-3 V Analog signal output (” D+ & D-” on Micro USB). Black GND (“GND” on Micro USB). Package Content: 2* Plantmate Capacitive Soil Moisture Sensor;. 2* Miro USB adapter;. 2* 4 pin header.

Review: Not as advertised - Sadly the USB board is a dual board and not single as shown in the picture. Updating the review to 5 stars after I realised that the board can be separated. After some soldering I have a functional sensor
Review: Worked fine. No issues. - Was very easy to interface with an Arduino NANO IoT 33. Used the Plantmate to sense moisture level in flower pots (one in the house and one outside). The result of the moisture test was sent via WiFi to a website I created so I could see moisture levels every day on a chart. Probably totally unnecessary for me to build but I enjoyed doing it. You do need to calibrate them before use. After you connect them to whatever is going to receive the data you should get the value they report when dry (313 for me) and also the value they report when submerged in water (679 for me). This becomes the range of values which you can convert to 0-100%.

### ⭐⭐⭐ It works, but the wiring could be better
*by A***I on August 13, 2023*

I connected it over the core extension to the ESP 32 and further on to the cloud. It does read moisture outdoors. The only problem is the wires, they are lower quality. It was in the dirt for about a month, look at the connection.
