C43 Water Level Sensor & Liquid Water Droplet Depth Detection

20.00 EGP

Water detection sensor is used to detect water leak, water level or rains. This is obtained by having a series of parallel wires exposed traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.

Description

Key Features:

✔ Detection Method: Conductivity-based (works with water and conductive liquids)
✔ Output Options:

  • Analog Output (0V–5V, varies with water depth)

  • Digital Output (TTL, adjustable via sensitivity potentiometer)
    ✔ Operating Voltage: 3.3V–5V DC (compatible with Arduino, ESP8266, Raspberry Pi)
    ✔ Probe Material: Corrosion-resistant nickel alloy (long lifespan)
    ✔ Detection Area: 10mm × 40mm exposed traces (measures droplets to submersion)
    ✔ Response Time: <100ms (fast detection)
    ✔ Module Size: 20mm × 60mm (compact PCB design)

Applications:

  • Smart Plant Monitoring – Soil moisture detection for automatic irrigation

  • Leak Alarms – Flood detection in basements/industrial equipment

  • DIY Projects – Water level indicators for tanks, aquariums, or coffee makers

  • Weather Stations – Rainfall measurement

How It Works:

  1. Analog Mode: Output voltage increases with water depth (0V = dry, ~4.5V = submerged).

  2. Digital Mode: Outputs HIGH/LOW when liquid crosses a set threshold (adjustable via potentiometer).

Wiring Example (Arduino):

  • VCC → 5V

  • GND → GND

  • A0 → Analog input (for depth measurement)

  • D0 → Digital input (for on/off detection)

Package Includes:

  • 1× C43 Water Level Sensor Module

Why Choose the C43 Sensor?

✅ Budget-Friendly – Cheaper than ultrasonic/optical sensors
✅ Easy to Use – No calibration needed for basic detection
✅ Low Power – Suitable for battery-powered projects
