How does soil moisture sensor works?

Soil moisture sensors measure the water content in the soil and can be used to estimate the amount of stored water in the soil horizon. Soil moisture sensors do not measure water in the soil directly. Instead, they measure changes in some other soil property that is related to water content in a predictable way.

How can I make a soil moisture sensor at home?

What are the components of soil moisture sensor?

The main component of the project (apart from the Arduino UNO) is the Soil Moisture Sensor. It consists of two parts: The main Sensor and the Control Board. Sensor part of the Soil Moisture Sensor consists of a couple of conductive probes that can be used to measure the volumetric content of water in soil.

What do you need to make a moisture sensor?

Required parts:-

1. galvanized nails 2″ – 2piece.
2. A bottle cap 1″ wide – 1 piece.
3. 10k ohm 1/4 watt resistor.
4. few female jumper wires.

What are the specifications of a moisture sensor circuit?

This sensor measures the volumetric content of water inside the soil and gives us the moisture level as output….Specifications.

Which IC is used in soil moisture sensor?

LM393 Comparator IC is used as a voltage comparator in this Moisture sensor module. Pin 2 of LM393 is connected to Preset (10KΩ Pot) while pin 3 is connected to Moisture sensor pin.

How do you test a soil moisture sensor?

Take the dry soil and place the Soil Moisture Sensor into the soil. If the blue LED lights up and the Serial Monitor says values less than 600, the setup has worked! On the other hand, for the wet soil, the Serial Monitor should have values above 600 and the yellow LED should light up.
