Electronic fluid level controller

Managing liquid levels in tanks is a common challenge across home, agricultural, and industrial automation systems. Whether dealing with a rooftop water tank or a chemical reservoir in a processing plant, maintaining the correct fluid level is crucial to prevent overflow, avoid dry-run damage to pumps, and reduce unnecessary power consumption. To address this challenge, we have designed a compact and reliable electronic limit switch module. This microcontroller based controller automates fluid level regulation with precision and ease. Prototype build of electronic limit switch module. Traditional fluid level control methods often rely on mechanical float switches and simple relay logic. While effective, these methods can suffer from issues such as bounce noise, relay chattering, and wear over time. This module modernizes this process by integrating microcontroller based debounce filtering, hysteresis, and control on/off delays. To perform its operation, the module utilizes two fl...

Alarm unit for limit switches or flow switches

Have you ever faced the frustration of dealing with an overflowing tank or a pump running dry? These unexpected events can result in costly damage and inconvenience. A reliable floater switch alarm system can provide early warnings, allowing you to take prompt action and prevent further issues. This project guides you through building a do-it-yourself floater switch alarm system using a PIC12F508 microcontroller. The circuit for this project is relatively simple and requires very few components. The system is designed to operate with a 12V DC power supply and utilizes a 230V AC buzzer unit for audible alerts. Prototype version of the alarm controller. The circuit includes a mute function that allows you to temporarily silence the alarm for a specified duration. Additionally, a built-in timeout mechanism ensures continuous alarm activation if the floater switch remains closed for an extended period, indicating a potential emergency. This project is suitable for various applications, in...
