The supplied information is sufficient for most users (power+analog signal out). It is not interchangeable with a resistor type, due to operating voltage 3.3 in this case (3.3-5V for resistor type) and the signal logic which is inverse: higher humidity, lower signal voltage.

When I start reading it goes down to zero in increments. If I put it into soil I first get a good reading, then it starts going down to 0 and stays there. Faulty device or do I do anything wrong?

yes it gives reading with - , in the code you have to provide a map recording to the reading.

is it water proof ? what if it gets submerged in water ?

impermeabile ma attenzione alla parte elettronica superiore

It work under Zigbee protocol?

it's just a sensor, then it's connected to a microcontroller that supports zigbee

What is the maximum operating voltage? Does it also work with 5V or 7V? How much is the supply current?

the maximum voltage supported is 3.3v a converter is required if you supply at a higher voltage

This capacitive soil moisture sensor is distinguished from most resistive sensors on the market and uses capacitive sensing to detect soil moisture. The problem that the resistance sensor is easily corroded is avoided, and its working life is greatly extended.

The sensor has a built-in voltage regulator chip that supports a 3.3 V/5V working environment, which means it works even on a 3.3 V/5V control board. A miniature PC such as the Raspberry Pi only needs an external ADC (analog to digital signal) conversion module to work.
With an external screen and a motherboard, you can talk to your plants! See if it is thirsty and you don't need more water to moisten.
Operating voltage: 3.3 V/5V
Output voltage: 3.3 V/5V
Interface: PH2.54-3P
Size: 98 x 23mm (LxW)

Package Included:

1 x Capacitive Soil Moisture Sensor

Product Safety Information

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
