## Overview

The Songhe Capacitive Soil Moisture Sensor Module operates on a 3.3 to 5.5V range, featuring a corrosion-resistant TL555 PCB for enhanced durability. It provides real-time, accurate soil moisture readings via a capacitive sensor, eliminating the common corrosion issues of resistive types. Designed for easy integration with Arduino and Gravity 3-pin interfaces, this compact 98x23mm module comes in a 5-pack, ideal for smart gardening and intelligent agriculture applications.

## Description

Because many people say that NE555 can’t work, now it changed to TL555,you can potting to extend the corrosion of PCB. Now we are seeking opinions on this one, KB material PCB, or aluminum substrate PCB, if you have better opinions, you can contact us It can avoid the problem that the resistive sensor is easily corroded, which greatly prolongs its working life. In contrast to the normal resistive sensor, this capacitive soil moisture sensor has no adjustable switching contact. It changes with the humidity. Thus displays the exact humidity values ​​in real time. Just need purchase an extra LCD Display and a microcontroller board with analog input from our store. You can give your plants the best possible care!

## Questions & Answers

**Q: do you have a library for the arduino?  How do I calibrate these?  Getting an analog reading does not mean anything..**
A: Take a reading while they are dry (that's your 0% reading), then take a sample of your soil and put it in a pot, insert the sensor and then water the pot until it can't hold any more water, then take another reading that's 100% saturated.
If you want you can put the sensor near a plant and see what level it reads when the plant looks stressed from to little water and make sure you keep it wetter than that.
Note: unless you are measuring pots, the moisture level near the surface is about useless for most plants unless they have very shallow roots..  for plants with deeper roots you probably want to waterproof the top portion of the sensor and bury it about 18" down.

**Q: What is the max distance from a pi  using 3v3 and using cat5 cable can the sensor be and still work ok?**
A: so not sure if you still need this answered or not, but for others it might help.
Im using an Arduino 5v, I used about 10 feet of cat5 cable from arduino to sensor. it changed the value some but you just need to calibrate it for that change.
example,
Arduino to senor without cat 5 = wet "850" / dry "450"
arduino to sensor with 10 feet cat 5 =  wet "700" /dry "300"

**Q: how does this work? do i have to connected to something else?**
A: Yes. Depends on what you want to do with it.
The output is a voltage value. You can connect to an Adruino type device to display it as analog or convert it to a calibrated digital display of percent moisture.

**Q: Will this work (as is) with the Micro:bit?**
A: I dont know understand your question. I plugged it into a data port on a esp 8266 read the data using C+ and  calibtrated it to meet my needs and transmitted it to a Blynk Control Panel  on the internet.
