Description
Abstract:
The Moisture-Based Watering ON/OFF Water Pump System circuit, based on a moisture sensor, LM393 comparator IC, and relay, automatically activates the water pump in the absence of moisture. The LM393 IC compares the input from the moisture sensor, turning the water pump on when soil moisture drops below the desired level, and turning it off when moisture is detected.
Application of the Circuit:
Most moisture-based systems in the market rely on costly soil moisture sensors and complex circuitry. This kit uses readily available soil moisture sensors, ensuring reduced costs and simpler circuitry. Ideal for detecting moisture levels and automatically controlling water pumps to maintain optimal soil moisture.
Why This Particular Circuit:
Soil moisture detection is simplified with this system, utilizing a readily available sensor to detect moisture levels. The circuit operates on a standard 5V DC supply, ensuring compatibility with common power sources.
Explained Working of Circuit:
The Moisture-Based Watering ON/OFF Water Pump System circuit uses a soil moisture sensor as the detection device. The LM393 IC compares the sensor output to determine moisture levels. A relay acts as a switch, turning the water pump on in the absence of moisture and off when moisture is detected.
How to Build:
Follow the detailed manual, circuit diagrams, and PCB layout included in the kit. Solder components to their designated positions on the PCB, ensuring correct polarity.
Testing the Kit:
Connect a 5V DC power source and manually induce water in the soil. The water pump activates only in the absence of moisture. Adjust the resistive value of the variable resistor (R2) to set the desired moisture detection threshold.
ICs Used:
The LM393 dual comparator IC is the key IC, ensuring reliable operation for moisture-based detection.
Part List:
- Semiconductors: LM393 IC
- Resistors: 10k Ohm (R2 variable), 1k Ohm (R3, R4)
- Capacitor: 1uF
- Miscellaneous: Moisture sensor, red LED, green LED, relay, PCB
Key Applications:
Ideal for electronics, automation, robotics, and educational projects, especially in Indian and international environments.
Keywords:
- Moisture-based watering system
- on/off water pump system
