The rain sensor detector can detect raindrops water, so it can be used for detection systems that perform functions required when it begins to rain.
This module consists of a series of printed conductor paths on a Bakelite plate.
This is a simple water sensor, can be used to detect soil moisture
Module Output is high level when the soil moisture deficit,or output is low
Can be used in module plant waterer device, and the plants in your garden no need people to manage
Operating voltage: 3.3V~5V
Dual output mode,analog out..
Product description: Water Sensor water level sensor is an easy-to-use, cost-effective high level/drop recognition sensor.which is obtained by having a series of parallel wires exposed traces measured droplets/water volume in order to determine the water level. Easy to c..
DESCRIPTION:You just need to connect to Arduino interrupt pin 2, and can measure the number of PWM pulse/interrupt per unit of time. The water flow would be directly proportional to the number of measured pulses.
