  • Raindrops and control panels are separate,  convenience of the line out.
  • Large raindrops board, more conducive detected rain.
  • Board with positioning holes to facilitate installation
  • Working Voltage: 3.3Volt / 5Volt DC
  • Power indicator, the output signal LED indicator.
  • TTL-level output, TTL output valid signal is low.
  • Driving capability around 100mA.
  • Output signal can directly connect to microcontroller, relays, buzzer, small fan, and etc.
  • Sensitivity adjustment by trimpot.
  • LED lights up when there is no rain output is high, and when rain drops up, output is  low, LED lights off.
  • Control panel size : 3 * 1.6 MM
  • Rain drop detection module size : 5.4 * 4.0 MM

How this item working?

Digital Output
When connected to a 5V supply power lights, no water droplets on-board sensors, DO/ data output is high, switch lights ON, and where drop of water, DO/ data output is low, the light indicator ON. Brush above water droplets, has returned to output high state.

Analog Output
AO/ analog output, you can connect the microcontroller to detect/ make calculation from AD and calculate of rain drop size.

DO TTL Output
DO TTL digital outputs can also be connected to the microcontroller to detect whether there is rain.
