Water Sensor is simple and easy to use, and high cost performance, water/water identification detection sensor; Exposed through a series of parallel wire line mark to measure the water droplets/size to determine water level. Easy to complete the water to the conversion of the analogue signal, output of the simulation values can be read directly by Arduino board, to achieve the effect of water level alarm. When powered a red LED will burn. (pin-out, sketch). With the simplest of test programs I just analogRead this sensor. It reads 0 when dry and it gets higher up till 550 when dimpled entirely in a glass of drinking water. At least, that is the theory.
It turns out that chemistry works like predicted. An oxidation process destroys the sensor within days (see image). We can do 2 things to improve the lifespan of this sensor: First: make less measurements. Second is to swap the Vcc and Ground connections per measurement. This should ensure that the metal stays a metal in stead of changing into a salt. Since this sensor has its own electronics it is not possible to swap the pins. All together: this sensor is useless for us. We better use the soil humidity sensor.
