Description

According Circuitstoday blog mentioned that This project is about a moisture-sensing automatic plant watering system using 8051 microcontroller. The system simply senses the moisture level and switches on the irrigation pump when the moisture is below the set limit. The system switches off the pump when the moisture rises above the set point. The moisture level threshold can be set using a trim pot on the system. The status of the pump (whether ON or OFF) is displayed on a 16×2 LCD display. The system can be divided into three section as follows.

Sensing prob.

YL 69 moisture sensing probe is used to sense the moisture here. It is simply a fork-shaped PCB with tracks running on both sides of the legs.  Just plug this probe into the soil where you want to sense the moisture.

Comparator circuit.

YL 38 comparator module is used in this project. It is a single channel opamp comparator based on L393 IC. This module just compares the output voltage of the sensing probe with a reference voltage and switches its voltage appropriately for the microcontroller to read.
