– TTL output
– TTL output effective signal is low level
– Drive capability: About 100mA
– Can directly drive relay, buzzer, fan
– The sensitivity can be adjusted by potentiometer
– The LED will light up the high level as no rain
– As it rains, output will be at low level, and LED will be on
– Application: DIY project and other electronic products

Usage:

Rain sensors are used in the detection of water beyond what a humidity sensor can detect.

 

How it works:

The rain sensor detects water that completes the circuits on its sensor boards’ printed leads. The sensor board acts as a variable resistor that will change from 100k ohms when wet to 2M ohms when dry. In short, the wetter the board the more current that will be conducted.

 

Pins:

A0………. Analog output

D0……… Digital output

GND….. Ground

VCC…… Positive voltage (input: 5v for analog 3.3v for Digital.)

Loop Pins:

+ ………. Sensor board hookup A

– ………. Sensor board hookup B

 

Dimensions:

2.17 in x 1.57 in x 0.31 in (5.5 cm x 4.0 cm x 0.8 cm)

 

Weight:

0.28 oz (8 g)

Step 2: Testing and Troubleshooting:

 

Testing and Troubleshooting:

 

Testing:

To test the Rain Sensor and ensure that it is working correctly connect the VCC to a 5v power source and GND. Try placing a few droplets of water on the Rain sensor detection board and the D0-LED should light up.

 

Troubleshooting:

If the D0-LED does not light up check the following:

Is the module hooked up properly?

Sometimes salinity is an issue with these units, this one worked fine with filtered, bottled water, but in some instances you may have to add a bit of salt to increase the waters conduction.

This might be a bit more tricky, but for some reason two different models by two different manufacturers have had defects in their soldering skills. Make sure all of the little SMD’s and connectors have been soldered on properly. IE – are solder joints actually soldered?

If none of the previous makes the D0-LED light up, your sensor may be defective.

Step 3: Wiring to an Arduino:

 

Wiring to an Arduino:

To wire the Rain Sensor to the Arduino for analog, simply connect the following as shown:

 

Rain Sensor …………….. Arduino

VCC…………………………. 5v

GND………………………… GND

A0……………………………. Analog in 0

Rain Sensor ……………. Sensor Board
