9-12V Automatic Water Level Controller Board Module Supports Automatic Water Pumping and Drainage
Description:
The water level controller is developed according to the actual pumping needs of households, factories and mines. It is used to control a high-current relay that detects the water level of a pool (water tower). It features small size, simple wiring, small power consumption, large switching capacity, strong anti-interference and high functional stability.
It can automatically turn on a pump when a pool (water tower) is short of water. When it is full of water, the controller will automatically stop pumping.
It is suitable for automation equipment manufacturers, DIY enthusiasts and school teaching.
How it works?
There are three probes (wires), namely S, Z and X. When two of the probes leave the water, the relay will be closed. When the three probes are soaked in water, the relay will be open.
Package Included:
- 1 x Water level controller
Note:
- Water level can be directly sensed with household wires (used as probes). The probes use micro-electric signals and have no effect on humans and other living things. Thus, it is safe to use. Peel one end (over 5cm/2") of wires so that they become bare wires to contact water and sense. To make the wires more durable, it is recommended to use aluminum wires or stainless steel where the wires come into contact with water.
