Imagine a smart irrigation system that precisely measures soil moisture, or a leak detector that immediately alerts homeowners to pipe bursts, preventing costly water damage. Thingbits India's newly launched water level and leakage detection sensor provides a cost-effective, highly sensitive solution for these applications and more.
The sensor operates on the principle of water conductivity, using exposed PCB tin-plated copper traces to detect water presence. Its simple yet effective design offers reliable performance at a low production cost, making it suitable for diverse applications including agricultural irrigation, residential leak detection, and industrial liquid level monitoring.
Technical Specifications and Operation
The analog-output sensor operates within a 3V to 5V DC range. Its PCB features ten copper traces arranged in an alternating pattern of power and sensing lines. Under dry conditions, these traces remain electrically isolated. When submerged, water bridges adjacent traces, altering the circuit's conductivity.
An onboard transistor connected to these interlocking traces outputs an analog signal when detecting moisture. This signal can interface with microcontrollers to trigger appropriate responses. While capable of both analog and digital output, the manufacturer recommends using it primarily as an on/off detection device rather than for precise water level measurement.
