Rain detector circuit Diagram
Rain detector circuit can be applied to the project or any other hobby, which is so simple principles.When it rains plate (sensor) will receive rain. And a dedicated work has paid to SCR1 and flow control Buzzer noise.
Electronic Part List
R1 1K 1/4 W Resistor
R2 680 Ohm 1/4 W Resistor
D1 1N4001 Silicon Diode
BZ1 12V Buzzer
S1 SPST Switch
SCR1 C106B1 SCR 106CY
SENSOR See
Notes
The sensor is a small piece of PC board etched to the pattern showen in the schematic. The traces should be very close to each other, but never touching. A large spiral pattern would also work. 2. Make sure to use a loud buzzer
