The LM393 rain sensor module is a simple and easy-to-use device that can use to detect rain. This Rain/water drop detection sensor consists of a printed circuit board (PCB) with a sensing pad and a comparator IC. The sensing pad is made of a conductive material, such as nickel, and when it is wet, the resistance of the pad decreases. This change in resistance is detected by the comparator IC, which outputs a digital signal.
The LM393 rain sensor module can power with +5V or +3.3V. The input voltage of the sensor is determined by the power supply voltage that you choose. If you are using a 5V power supply, the input voltage of the sensor will be 5V. If you are using a 3.3V power supply, the input voltage of the sensor will be 3.3V.
The LM393 rain sensor module works on the principle of resistance change. The sensor has a sensing pad that is made of a conductive material, such as nickel. When the sensing pad is dry, the resistance of the pad is high. When the sensing pad is wet, the resistance of the pad decreases.
The sensor also has a LM393 comparator IC. The comparator IC compares the voltage on the sensing pad to a reference voltage. When the voltage on the sensing pad is lower than the reference voltage, the comparator IC outputs a high signal. When the voltage on the sensing pad is higher than the reference voltage, the comparator IC outputs a low signal.

LM393 Rain Sensor Module Specifications : –
The LM393 rain sensor module is a simple and easy-to-use device that can use to detect rain. It is a good choice for applications where you need to detect rain in a simple and reliable way. When it is raining, the sensing pad gets wet, which decreases the resistance of the pad. This causes the voltage on the sensing pad to decrease. When the voltage on the sensing pad decreases below the reference voltage, the comparator IC outputs a high signal. This high signal is then used to trigger an output device, such as an LED or a buzzer.
Here are some of the specifications of the LM393 water drop sensor:
Input voltage: The LM393 water drop sensor can power with +5V or +3.3V.
Output signal: The output signal from the sensor is a digital signal that is high when a water droplet is detected and low when it not detected.
Sensitivity: The sensitivity of the sensor can adjust by using a potentiometer.
Range: The range of the sensor is affected by the size of the sensing pad. A larger sensing pad will have a longer range than a smaller sensing pad.
Temperature range: The LM393 water drop sensor can use in a wide range of temperatures, from -40°C to 85°C.
Humidity range: The LM393 water drop sensor not affected by humidity, so it can use in humid environments.
LM393 Rain Sensor Module Pin Descriptions : –
The sensor also has a potentiometer, which can use to adjust the sensitivity of the sensor. When the potentiometer is turned clockwise, the sensor will become more sensitive. When the potentiometer is turned counterclockwise, the sensor will become less sensitive.
Here are the pin descriptions for the snow/raindrops detection sensor module:
VCC: The power supply pin, which should be connected to 5V.
GND: The ground pin.
OUT: The digital output pin, which will be high when it is raining or snowing and low when it is not.
S: The sensing pad, which is made of a conductive material. When the sensing pad get wet, the resistance of the pad decreases. This causes the voltage on the sensing pad to decrease. When the voltage on the sensing pad decreases below a certain threshold, the OUT pin will go high.
