Soil Moisture Sensor
A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It is ideal for monitoring garden, or your plant’s water level. This is a must have tool for a connected garden.
This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).
It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden. The IO Expansion Shield is the perfect shield to connect this senor to Arduino.
The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation.

TDS (Total Dissolved Solids) measures how many milligrams of soluble solids dissolved in one liter of water. The measure is expressed in PPM (part per million). In general, the higher the TDS value, the more soluble solids dissolved in water, and the less clean the water is. Therefore, the TDS value can be used as one of the references for reflecting the cleanliness of water.
Thanks to this product, it becomes possible to create your own measurement, collection and data transmission system. It is even possible to use this information to automate water treatment cycles. The TDS probe is waterproof; it can be immersed in water for long time measurement. However, the signal transmitter board is not waterproof.

This is an industrial grade soil and water PH and temperature sensor. The new generation Ph sensor can measure pH and temperature level in both soil and water as well. Soil and water pH is a measure of the acidity or alkalinity of the soil or water. Soils (or water) can be classified according to their pH value where 6.5 to 7.5 is neutral soil (Ideal soil for growing plants), over 7.5is alkaline and less than 6.5 is acidic. The sensor has RS 485 serial interface with 2-meter cable which can be extended to 1000 meter without affecting measured data quality, thanks to RS 485 long distance serial communication interface. It can be integrated with GPRS/4G/WIFI/LORA wireless module.
