Mini Water Tank Tower Pool Automatic Pumping Controller Level Detection Sensor Module Designed to Control the Relay | Инструменты

The product is based on the detection of water (water tower) to control the high current relay water level to achieve control. It has so many advantages, such as small size, convenient wiring, low power consumption, large switching capacity, strong anti-interference and high functional stability, etc. ? ?
Features: Designed to control the relay and then control to pump water or drain away water according to water level.  Mini size, easy wire connection. Low power consumption, large switching capacity. Strong anti-interference and high functional stability.  Great for pool or water tower to control the water level. The product is the best choice for automation equipment manufacturers as ancillary products, is also the DIY artifact vocational school students practical teaching best artifact!
Probe line instructions: The probe is a three-wire system, A is a high water mark, B is a low water mark and C is a test common line. Probe water level arrangement: A place the highest water level ceiling, B place lower water level lower limit, C place the lowest water level. B which is slightly higher than C. Probe detection principle: the board is connected to the power to start work, test the water level, when the probe detects the water level below point B, that is no water, the device starts pumping, when the water reaches point A, the water is full, the relay off Electricity and stop pumped; when the water level is slowly dropped below point A until less than point B, no water was detected, and equipment pumping was started. Probe production and sensitivity: This product requires stainless steel probe, or household wire can replace the probe, the wire stripping more than 20 cm, making it a bare wire can be directly sensed (many people react: the relay is not released, the water is full But keep pumping. Prove the probe is too small, low sensitivity can not be sensed, please make the probe area bigger, increase the contact with water, reduce the water resistance, the greater the sensitivity of the probe to do the higher).
Notes: The product is not equipped with probe, don't need to buy probe neither. Just strip the electric wire 2cm to instead of probe, make it become bare wire then can induce directly. ?? Specifications: Power Supply: 9-12V AC or DC 12-15V (DC input, regardless of positive and negative) Relay control output: Less than AC 10A 250V or DC 10A 30V Equipment (water pump, solenoid valve) PCB Size: 70 *40*25mm Product Weight: 27g/ 0.06lb
