    18650 Lithium-Ion Battery Cell

    Technical Overview, Specifications, Applications, and Operating Characteristics

    Short Overview

    The image depicts a standard cylindrical 18650 rechargeable Lithium-Ion (Li-ion) battery cell featuring an orange high-temperature PVC shrink wrap. The designation ‘18650’ directly specifies its physical dimensions: 18 mm in diameter and 65 mm in height, with the ‘0’ indicating its cylindrical form factor.

    Renowned for high energy density, low self-discharge rates, and high nominal discharge voltage (~3.6V–3.7V), 18650 cells serve as fundamental building blocks for both standalone portable electronic devices and multi-cell battery packs used in electric vehicles and renewable energy storage system (ESS) modules.

    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.
