Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ Condition: New _x005f_x000D_ Power Supply Voltage: 9V-12V (AC, DC Can Be) (Note: For Safety Reasons, Please Do Not Use Switching Power Supply) _x005f_x000D_ Control Output: Current 0 ~ 10A (Genuine Relay) _x005f_x000D_ Control Power: 0~1kw/220v (Theory Can Control 2kw) _x005f_x000D_ Product Size: 58.00x50.00x22.00mm/2.28x1.97x0.87inch _x005f_x000D_ 1. This product is developed according to the actual needs of pumping water in family factories and mines. The product is based on the detection of pool (water tower) water level to control the high current relay to achieve control. _x005f_x000D_ 2. It is characterized by small size, easy wiring, small power consumption, large switching capacity, strong anti-interference and high functional stability. _x005f_x000D_ 3. It can stably realize the automatic opening of the water pump when the pool (water tower) is short of water, and stop the water pump automatically when it is full. _x005f_x000D_ 4. This product does not require the purchase of another probe, with household wires can replace the probe. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ The so-called probe is a wire with a plastic mesh shell to buckle up the wire, with household wires can be directly inducted, the wire stripped 3 cm or so, so that it becomes a bare wire can be directly inducted. In order to be more durable for a longer period of time, it is recommended to connect the point of stainless steel in contact with the water will be better! This product does not come with a wire (probe) _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1*Liquid Water Level Controller Sensor 1.Power Supply Voltage: The 12V liquid water level controller sensor stands out with its operating voltage of 12V. This means it can be powered by a standard 12V DC power supply, making the installation and usage process relatively simple. 2.Automatic Control: This water level detection sensor features automatic control functionality, allowing it to start and stop the water pump operation based on preset conditions or sensor signals. For example, it can automatically start the pump for water extraction when the water level reaches a certain height. Similarly, it can cease the pump operation when the water level drops to another predetermined value. 3.Water Supply and Drainage: Not only does this liquid level controller sensor module enable water extraction and supply, but it also supports drainage function. This versatility makes it suitable for various applications such as pools, reservoirs, basement drainage, and more. 4.Reliability: As water pumping and control tasks often require prolonged operation, reliability is crucial for the automatic water level controller module. It typically incorporates high-quality components and designs to ensure stable and long-lasting performance. 5.Safety: Safety is a paramount consideration for any electronic device. The 12V water level detection sensor board is equipped with multiple safety protection features, including overcurrent protection, overheating protection, and short circuit protection. These safeguards ensure timely shutdown in case of abnormalities, preventing equipment damage or potential safety hazards like fire incidents.
