2 pièces humidité capteur de pluie Gouttes de pluie Pluie reconnaissance Module capteur Comparateur LM393

Product parameters: Operating voltage: 3.3V-5V, Output form: Digital switching output (0 and 1) and analog voltage output (AO), Small PCB size: 32 x 14 mm. Equipped with screw holes for easy installation.

The rain sensor module can be used to detect rain, determine rainfall intensity, and as a switch. The control module has an adjustable switching contact with a potentiometer and an LM393 comparator. The module is directly equipped with a high-performance relay for direct load control.

High quality: The sensor is made of double-sided material with a large surface area of 5.0 x 4.0 cm / 1.97 x 1.57 inches, and the surface is treated with nickel plating, which offers anti-oxidation, high conductivity, and a long lifespan.

Note: The raindrop sensor board must be wiped clean after each use; otherwise, the raindrop signal output may still be detected. High-Gain Comparator: This module uses a wide-gain voltage comparator, providing a clean signal with a good waveform and strong driving capability (greater than 15 mA). It is equipped with an adjustable precision potentiometer for sensitivity adjustment. Product Use: This robot kit, raindrop sensor, and rain sensor can be used to monitor various weather conditions and convert the signal into digital signals and outputs.
