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. The Separation Between Tracks Is Very Small. What This Module Does Is Create A Short Circuit Whenever The Wet Tracks.
Water Causes The Creation Of A Low Resistance Path Between Tracks With Positive Polarity And Tracks Connected To Gnd. It Has A Specifically Integrated Circuit Lm392 Op Amp.
This Is Responsible For Amplifying The Small Differential Voltage Which Is Generated When A Drop Of Water Falls On The Track Module. Voltage: 3.3vdc To 5vdc. Output Signal: Analog And Digital.
