<h3>Product Overview</h3> <p>The "Water Tank Overflow and Water Flow Sensor Alarm Circuit Board" from KJMIndia is a highly sophisticated and meticulously designed solution aimed at preventing water wastage through overflow in tanks. Tailored for both commercial and project applications, this premium quality circuit board offers reliable and efficient monitoring of water levels in tanks ensuring sustainable water management. The package includes an expertly designed readymade board fitted with a buzzer, a push button switch, a 2-pin RMC wire for sensing, and two 3mm LEDs—one green and one red for indicating status—making it a comprehensive and ready-to-use system.</p> <h3>Key Features</h3> <h4>Premium Quality</h4> <p>The circuit board boasts premium build quality suited for demanding commercial applications and academic projects. Each component is carefully selected to ensure longevity, reliability, and consistent performance under various conditions.</p> <h4>Visual and Audible Indicators</h4> <p>With integrated visual and auditory signals, users are promptly alerted when the tank reaches its full capacity through a loud buzzer and illuminating LEDs: - <strong>Power LED Indicator</strong>: Confirms that the system is operational. - <strong>Tank Full LED Indicator</strong>: A red LED lights up when the tank is full. - <strong>Tank Full Alarm</strong>: A buzzer goes off to notify that the tank's capacity has been reached, preventing overflow.</p> <h4>User-Friendly Operation</h4> <ul> <li><strong>Momentary Switch</strong>: A thoughtfully added push-button switch allows users to quickly mute the alarm. This is particularly useful to avoid continuous alarm sound once the condition (tank full) has been acknowledged.</li> <li><strong>Persistent Alarm Control</strong>: Innovatively designed to retain the alarm-off setting even after a power failure and subsequent restoration. This unique feature eliminates the need to manually reset the alarm condition after every power cycle.</li> </ul> <h4>Flexible Sensing Options</h4> <p>This versatile circuit offers multiple methods for tank water level detection: - <strong>Metal Sensors</strong>: Any conductive material including metal rods can be used. - <strong>Float Switches</strong>: Integrated or third-party float switches are compatible. - <strong>SS Bolt &amp; Nuts</strong>: Simple stainless steel nuts and bolts can serve as efficient and cost-effective sensors.</p> <h4>Power Specifications</h4> <p>The board operates efficiently at 9V AC, leveraging a stepdown transformer (0-9, 500mA). Users can also opt for a 12V or above stepdown transformer, using the on-board 7812 voltage regulator IC to ensure consistent and safe voltage levels. This flexibility in power options underscores the adaptability of the system for various setup preferences.</p> <h3>Package Content</h3> <p>The product package includes: - <strong>1 x Readymade Circuit Board</strong>: Fully assembled board with all essential components mounted and tested. - <strong>1 x Buzzer</strong>: Emits a loud audible alert when the tank is full. - <strong>1 x Push Button Switch</strong>: Allows for easy muting of the alarm. - <strong>1 x 2-pin RMC Wire for Sensing</strong>: Wire to connect sensor points. - <strong>2 x 3mm LED (Green and Red)</strong>: Indicators for power and tank full status.</p> <h3>Detailed Specifications</h3> <h4>Electrical Characteristics</h4> <ul> <li><strong>Operating Voltage</strong>: 9V AC (0-9, 500mA) or higher using stepdown transformer.</li> <li><strong>Voltage Regulation</strong>: Integrated 7812 voltage regulator IC for stable output with higher input voltages.</li> </ul> <h4>Components and Materials</h4> <ul> <li><strong>Circuit Board</strong>: High-quality PCB with robust tracks and solder joints.</li> <li><strong>Buzzer</strong>: Loud piezoelectric buzzer with a sharp, attention-catching sound profile.</li> <li><strong>Push Button Switch</strong>: Durable momentary switch for silencing alarms.</li> <li><strong>LED Indicators</strong>: Two 3mm LEDs—green for power, red for tank full indication.</li> <li><strong>2-pin RMC Wire</strong>: Sturdy wire suitable for reliable sensor connection.</li> <li><strong>Sensor Compatibility</strong>: Compatible with float switches, metal probes, SS bolts, or any conductive material that can serve as a sensor.</li> </ul> <h3>Application and Installation</h3> <p>The Water Tank Overflow and Water Flow Sensor Alarm Circuit Board from KJMIndia is designed for ease of installation and use: 1. <strong>Mounting</strong>: Secure the circuit board in an accessible and safe location near the water tank. 2. <strong>Power Connection</strong>: Connect the board to a suitable 9V AC power source or use a higher voltage transformer with the 7812 voltage regulator. 3. <strong>Sensor Setup</strong>: Connect your chosen type of sensor (metal rods, float switches, or SS bolts) to the 2-pin RMC wire and position them at the desirable water level. 4. <strong>Indicator and Alarm</strong>: Monitor the power status using the green LED indicator and tank full condition via the red LED and buzzer. Use the push button switch to silence the buzzer when needed.</p> <h3>Advantages</h3> <h4>Prevent Water Wastage</h4> <p>Deploying this alarm system helps in efficiently managing water resources by preventing overflow, thus conserving water—a crucial resource in many parts of the world.</p> <h4></h4>
