A water tank automatic control circuit

Description: After the 3.40V power supply, the voltage is reduced to 6.3V through a full transition rectification using VDi and V sulfone. The C1 filter provides voltage stabilization after the caution circuit operates at the NE555 voltage level. When the circuit operates under military drawdown conditions, the output at pin 2 of the NE555 shows a low position. This activates an internal circuit that triggers a rotary semi-relay action at pin 3, which in turn activates a dual touch relay, K1-1, to start the pumping motor while K1-2 is closed. Wiring at point C is shorted; when the water level rises to point A by one inch, the power supply voltage increases across resistor R. The voltage at pin 6 of the NE555 is elevated, which triggers the circuit when it reaches 2/3 of VDD. This causes the output at pin 3 to go low, releasing K1-1 and K1-2, thereby stopping the motor operation. The BG connection contacts short-circuit, and the system remains in a standby state until the water level drops below point A and point B. The toggle button K2 is used to manually activate the water gate for exploration purposes.

The circuit utilizes a NE555 timer IC configured in a monostable mode to control the operation of a pumping system based on water level detection. The initial voltage reduction from 3.40V to 6.3V is crucial for the proper functioning of the NE555, as it operates effectively within this voltage range. The C1 capacitor acts as a filter, smoothing out any voltage fluctuations that may occur during operation, ensuring stable performance of the caution circuit.

In this setup, the water level is monitored by a sensor connected to points A and B. When the water level rises to point A, the voltage across resistor R increases, which is sensed by pin 6 of the NE555 timer. Once this voltage reaches 2/3 of the supply voltage (VDD), the output at pin 3 transitions to a low state. This action deactivates the relays K1-1 and K1-2, thus stopping the motor and preventing overflow.

The dual relay configuration allows for redundancy and safety in the pumping operation. The K1-1 relay is responsible for starting the pump, while K1-2 serves as a safety mechanism to ensure the pump does not operate under certain conditions. The shorting of wiring at point C ensures that the system can quickly respond to changes in water levels, maintaining efficient operation.

The toggle button K2 provides manual control over the water gate, allowing for intervention when necessary, such as during maintenance or exploration. The design emphasizes reliability and responsiveness, making it suitable for various applications where water level management is critical.After 3t40V power Sutra T seats is reduced to 6.3V low voltage by VDi - V sulfone full transition rectified. c1 filter provide after - when caution circuit NI/555 operating vol tage: NE555 (2) llt when canthus under military drawdown point B; 0 showed a low position, Chong Mi touch internal circuit overturns, Rotary (3) pin output high power semi-relay action was electric, dual touch n - K1 -l closed Yu pumping motor is activated while closing Kl 2 B.
