3.quiescent current <3  mA

4.work temperature: -5℃~60℃

5.load capability of relay: (1A @ 250V AC) (1A @ 30V DC)

6.response rate: <50 ms

7.length of wire: 2000mm (or based on requirements)

8.packaging material: epoxy resin

Connection wire definition: 
1.red: DC power anode pole
2.black: DC power cathode
3.blue: alarm single (N.C) 
4.yellow:  COM port of alarm single 

5. green:  alarm single (N.O) 

Install method:
If you want to detect little water (length is not exceed 2mm), can put a sponge block on the floor and put sensor on it, sponge block absorb water, the detect probe can touch the water, sensor output alarm single.
If need more drive current, an outer drive circuit is needed.
