Product use:

Robot kits, rain sensor and can be used for all kinds of weather monitoring, and go down to set the output signal and the AO.

Product introduction:

1. Sensors use the high quality FR – 04 double material, large area of 5.0 x 4.0 CM, treatment of nickel plating and surface,

have fight oxidation, electrical conductivity, and life has more superior performance;

2. The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma;

3. With a potentiometer sensitivity adjustment;

4. The working voltage is 3.3 V to 5 V

5. The output form: digital switch output (0 and 1) and analog AO voltage output;

6. Small board PCB size: 3.2 cm x 1.4 cm

7. Using the LM393 wide voltage comparator

Function is introduced:

Connected to 5V power supply, the power indicator, no water droplets on induction plate, the DO output for the high level, switch lights out, a drop of water drops, the DO output for the low level, switch indicator,

Brush away the water droplets, return to again, the output high level…

AO analog output, can be connected to the microcontroller AD mouth drops of rainfall in the above size.

DO TTL digital output can also be connected microcontroller detecting whether it will rain.

Connection mode:

1. VCC: anode (3-5 v)

2. GND: connect the cathode of power

3. DO: TTL switch signal output

4. AO: Analog signal output

Package include :1 set rain sensor module
