Monday Kids Water Level Control Relay Kit - Automatic Water Pump Circuit Board DIY Kit

This product is a Water Level Control Relay Kit designed for electronic enthusiasts and students to learn and practice electronics skills. The kit includes all necessary electronic components and circuit board, allowing users to assemble and solder a complete water level control relay. It is ideal for students for electronic skills training and for electronic enthusiasts for DIY projects.

Product Parameters:

Model: TJ-56-16
Power Supply Voltage: DC 5V
Board Size: 71 x 69mm
 

Function Explanation: The water level (liquid) controller can achieve the following two functions (functions 1 and 2 are switched via button S1):

Automatic Water Filling:
LEDs of three colors indicate low (red), medium (yellow), and high (green) water levels.
When the water level is low, the relay is activated (external water pump operates) to add water. When the water level rises to the low water level, the relay deactivates, stopping the water addition. When the water level drops again to the low water level, the relay reactivates, and the process repeats. This function maintains the water level between the low and high levels.
Automatic Drainage:
LEDs of three colors indicate low (red), medium (yellow), and high (green) water levels.
When the water level is high, the relay deactivates (external solenoid valve operates) to start draining. When the water level drops to the low water level, the relay activates (solenoid valve stops working). When the water level rises again to the high water level, the relay reactivates, and the process repeats. This function maintains the water level between the low and high levels.
 

Circuit Principle: The entire system consists of a power module, LED indicator circuit, relay drive circuit, liquid level sensor circuit, relay drive, and sensor module. The power module provides a stable voltage, the LED indicator circuit shows the current water level status, the relay drive circuit controls the relay's activation and deactivation, the liquid level sensor circuit detects water level changes, and the relay drive and sensor module achieve the water level control function.
