Description

I2C Capacitive Soil Moisture and Temperature sensor I2C

Specifications

Arduino and Raspberry Pi client software libraries.

Dust and waterproof

Calibration functions for EC and Dielectric permittivity

Low cost and easy to use.

Fairly accurate readings

 

ParameterMin.TypicalMax.
Supply voltage (VCC), V2.53.33.5
Working current(VCC=3.3V), mA-1114
Operating Temperature Range, Celsius-202560

 

Dielectric permittivity (ε) (Temperature corrected) resolution: 0.1ε (avg.Tolerance 5%) and range 1 (air) to 80 (water)

(Experimental) Electrical Conductivity (mS/m) resolution: 0.01 mS/m (avg.Tolerance 30%)

Temperature (°C) resolution: 0.1°C and range: -20 to 60°C (avg.Tolerance 3%)

Degree of water saturation in the soil (%) resolution:0.1% and range: 0 – 100%

Volumetric water content - VWC calculation from Dielectric permittivity ε. VWC = 0.002974 * pow(ε,2) + 0.07424 * ε -1.295;

 

Raspberry Pi pin #1 - sensor red (3.3v)

Raspberry Pi pin #3 - sensor green (SDA)

Raspberry Pi pin #5 - sensor white (SCL)

Raspberry Pi pin #9 - sensor black (GND)

Raspberry Pi pin #9 - sensor shield(GND)

Documentation

Get software

 

This sample software demonstrates how to make a command-line interface for the sensor. The sensor default I2C address is 0x63.

To get the software to execute following on Raspberry Pi:

git clone https://github.com/tinovi/i2cRaspberry

 

cd i2cRaspberry

 

chmod 777 *.sh to add permissions for execute

 

./mk.sh to make demo executable

 

./read.sh to read data from the sensor

 

./svcs 0x63 addr 0x65 to change default address 0x63 to new I2C address: 0x65

 

Interfacing from Arduino

 

SDA and SCL lines require pullup resistors ~4.7k

 

Wiring to Arduino:

 

Arduino pin #3V3 - sensor red (3.3v)

Arduino pin #A4 - sensor green (SDA)

Arduino pin #A5 - sensor white (SCL)

Arduino pin #GND - sensor black (GND)

Arduino pin #GND - sensor shield (GND)

SDA and SCL lines require pullup resistors ~4.7k
