3.3-5V Rain Raindrops Detection Sensor Weather Humidity Module For Arduino
Brand New
Feature:
1.The sensor USES the high quality FR - 04 double material, large area of 5.5 * 4.0CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance;
2.With potentiometer sensitivity adjustment;
3.The output format: digital switch output (0 and 1) and analog AO voltage output;
4.Has a fixed bolt hole, convenient installation;
5.The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 mA;
6.The LM393, use of wide voltage comparator;
7.The working voltage of 3.3 V to 5 V;
Size: Like the picture show
Usage:
- Connected to 5 v power supply power lights, 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 state.
- 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.
DC5V Relay and DC12V Relay:
Product Usage:
Raindrops, rain, plant leaf surface humidity sensors, can be used for monitoring various weather conditions, with relay direct output, control motor and other start and stop.
product description:
1. The sensor adopts high-quality FR-04 double-sided material, with a large area of 5.0*4.0CM, and is treated with nickel-plated surface, which has superior performance against oxidation, electrical conductivity and life;
2. The module is directly equipped with a large power relay to directly control the load;
3. With potentiometer to adjust the sensitivity, control the opening of the relay when different water is controlled.
Features:
Connect the power supply, the power indicator light is on, when there is no water droplet on the sensor board, the relay pulls in, the related equipment is activated, the switch indicator light is on, a drop of water drops, the relay is disconnected, the switch indicator light is off.
Performance parameters:
Module power supply: 5V/12V (optional) Quiescent current: 5-12mA
Relay load capacity: 250V 10A (AC) 30V 10A (DC)
