water level controller circuit diagram

The circuit consists of a 555 timer IC configured as a multivibrator, which operates with two probes to measure the water level. When the capacitance between the probes indicates a high water level, the output from the 555 timer is low. Conversely, when the water level is low, the output switches to high potential. This design can be used to control water levels in a tank and can incorporate additional features such as light or infrared sensors. The circuit also includes a relay for controlling a three-phase pump motor, with components like infrared receiver diodes and optocouplers for signal processing. The relay used is a memory self-locking type, which requires a brief pulse to activate and can handle high current ratings.

The water level controller circuit employs a 555 timer integrated circuit (IC) configured in astable or monostable mode to monitor and regulate the water level in a tank. The two probes, positioned at different heights, serve as capacitive sensors. When the water level rises above the upper probe, the capacitance changes, signaling the 555 timer to switch its output from low to high. This transition can activate additional circuitry, such as a relay that controls a pump to maintain the desired water level.

Incorporating a decoder integrated circuit (IC3), such as the CX20106A, enhances the system's capability to process signals from infrared sensors (VD1, VD2, and VD3), which can be used for remote monitoring or control. These infrared components can be sourced as standalone units or integrated into a single module, which simplifies the design and improves reliability.

The relay in this circuit is a memory self-locking type, enabling it to maintain its state without continuous power. It requires a 20ms trigger pulse to activate and can handle substantial currents (up to 30A), making it suitable for controlling larger three-phase pump motors. This feature ensures that once the relay is engaged, it remains active until the system is intentionally reset, providing a robust solution for water level management.

Overall, this water level controller circuit is versatile and can be adapted to various applications, including irrigation systems, aquariums, and industrial water tanks. The inclusion of additional sensors and control mechanisms allows for a comprehensive automation solution that enhances operational efficiency and reliability in water management systems.It consists in 555 feet, respectively, of 1, 2-cited two-pin, using two needles with a high water level higher than 555 when the probe capacitance between 1, 2 feet circuit leaving 555 low potential output. Contrary to the output of high potential (555 composed of a standard multivibrator). For the control points up and down the water level 555 can also be used to do, good simple 3 floor Picture this subject as follows:to the file much better this time! 5th Floor Or more appropriate light or infrared sensor 6 F See ah. 7th Floor Unfortunately, not enough levels can not see ah! 8 F With a zoom control, it works in between the cut-off and saturation, thus to control a triac on and off the line, Oh 10 F Upstairs, "Lieutenant, " Hello, Can the "water level controller" information sent to my mailbox, aqiang_02318@sina.
