YL-83 Rain Detection Sensor

₹45.00

Overview

The YL-83 Rain Sensor Module (often paired with the Raindrops Detection Board YL-38 control board) is an easy-to-use electronic module designed for detecting rain and moisture presence. The system consists of two primary parts:

• Rain Sensing Board (Sensing Pad): A nickel-coated PCB board with interleaved conductive traces. When raindrops fall on the board, water bridges the copper tracks, decreasing electrical resistance across the tracks.
• Control Module Board: Based on the LM393 operational amplifier comparator, this board processes the resistance change from the sensing pad. It features an adjustable potentiometer to tweak sensitivity and offers dual output options: both Digital (HIGH/LOW) and Analog signals.

Key Feature Summary: Dual output mode (Analog for precise moisture depth, Digital for simple rain presence threshold), anti-oxidation nickel-plated sensor pad, adjustable threshold potentiometer, and onboard Power & Signal LEDs.

    Capacitive Soil Moisture Sensor v2.0 (HW-390)

    ₹55.00

    Overview

    The image depicts a Capacitive Soil Moisture Sensor v2.0 (specifically model HW-390). Unlike traditional resistive soil moisture sensors, which suffer from rapid corrosion due to direct electrical contact with soil, this capacitive sensor measures soil moisture content through changes in dielectric permittivity, avoiding exposed electrodes. It features an integrated voltage regulator (often TL431 or NE555-based circuitry) and delivers an analog voltage output corresponding to soil moisture level.

    • Corrosion-Resistant Design: Embedded inside non-conductive PCB trace layers, preventing oxidation in wet soil.
    • Analog Output: Delivers an analog voltage signal (AUOT/AOUT) directly proportional to soil capacitance.
    • Wide Compatibility: Works seamlessly with 3.3V and 5V microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi.
    • Integrated Regulator: On-board chip provides stable operation across varying supply voltages.
