Application: raindrop sensor robot kit. It can be used to monitor the weather condition and convert to the output DO (digital signal) and AO (analogue signal).
Note:
With the module, a rainfall board must be used. The module can output signals (DO, AO).
Instructions:
If the VCC input is DC 5V, the display is on. When rain falls on the sensor field, the DO outputs are output at a low level and the display remains on. Otherwise, no rain dripping, high level DO outputs and display will go out.
When the water is removed, the DO-LED recovers to a high electrical level.
Specifications:
IC Model: LM393
Rated operating voltage: 3.3-5V
DO: output digital signal.
AO: output analogue signal.
VCC: DC input, positive power supply
GND: function grounding, negative power supply
