Soil Moisture Detector Circuit using Gate IC

In this article, we will learn how to make Soil Moisture Detector Circuit using Gate IC.

In the last post, we learned how to make Automatic Air Conditioner ON/OFF Control System using Arduino.

 

 

 

Components Required:

  1. Soil moisture sensor
  2. Battery (9V)
  3. Regulator (7805)
  4. Buzzer
  5. LED
  6. Resistors
  7. NAND gate IC (7400)
  8. Jumper wires
  9. Breadboard

Circuit Connection:

  • Connect the soil moisture sensor to the power supply (5V) and ground.
  • Connect the output of the sensor to one of the inputs of a NAND gate in the IC.
  • Connect the other input of the NAND gate to ground via a resistor.
  • Connect an LED with a current-limiting resistor to the output of the NAND gate.

How it works:

  • The moisture sensor provides a signal to the NAND gate depending on the moisture level.
  • The resistor connected to ground sets a reference level.
  • When the soil is moist (conducting), the sensor output changes, affecting the input of the NAND gate.
  • If both inputs of the NAND gate aren’t receiving the same signal, it triggers the gate to output a signal.
  • This signal powers the LED, indicating the moisture level detected by the sensor.

Usages:

A Soil Moisture Detector Circuit using Gate ICs has various applications, primarily centered around monitoring and controlling soil moisture levels.

Some common usages include:

  1. Agriculture and Gardening
  2. Environmental Monitoring
  3. Smart Irrigation Systems
  4. Industrial Applications
  5. Conservation Projects
