Water quality checker project simple circuit diagram

How to measure water purity and test water quality using a simple electronics project. Water purity measurement and water quality analysis can be performed using a water purity checker circuit. This circuit is constructed around a Light Dependent Resistor (LDR) and several discrete components. A notable feature of this water purity tester is that it emits a beep sound when the water purity level falls below a specified threshold. This simple electronic project can be implemented in domestic water tanks for monitoring and testing water quality. The article provides a detailed circuit diagram and construction details for the water quality testing device. Additionally, it can be integrated with a previous circuit for a water tank level controller, resulting in an advanced engineering project. When the amount of mud in the water reservoir exceeds a threshold value, the water quality testing equipment produces a beep sound to alert users that the mud quantity has increased and requires cleaning.

The water purity checker circuit utilizes an LDR, which changes its resistance based on the light intensity that passes through the water. When water is clear, more light reaches the LDR, resulting in lower resistance. Conversely, as the water becomes increasingly contaminated, the turbidity increases, reducing the amount of light that reaches the LDR and causing its resistance to rise. This change in resistance can be converted into a voltage signal using a voltage divider circuit, which can then be monitored by a microcontroller or a simple comparator circuit.

To implement this project, the circuit typically includes a power supply, the LDR, a resistor for the voltage divider, a comparator (such as an operational amplifier), and a piezo buzzer for the alert sound. The comparator is set up to trigger when the voltage from the LDR exceeds a predetermined threshold, indicating poor water quality. When this condition is met, the comparator output activates the piezo buzzer, providing an audible alert.

For practical applications, the circuit can be housed in a waterproof enclosure to ensure durability and reliability in a wet environment. Calibration may be necessary to adjust the threshold according to specific water quality standards. The integration with a water tank level controller can enhance the functionality, allowing for simultaneous monitoring of both water purity and level, making it a comprehensive solution for water management in domestic settings. This project not only serves as a useful tool for ensuring water quality but also provides an educational opportunity for understanding basic electronics and environmental monitoring.How to measure water purity How to test water quality using a simple electronics project You can perform water purity measurement and water quality analysis using this water purity checker circuit.
