Keyestudio Water Level Sensor Droplet Detection Module for Arduino UNO R3

The Keyestudio Water Level Sensor Droplet Detection Module is an easy-to-use, portable, and cost-effective solution for measuring water levels and droplet volumes. It is ideal for South African students, educators, and hobbyists building environmental monitoring systems or automated smart home projects. This compact sensor easily integrates with Arduino UNO R3 and other popular development boards.

Analogue droplet detection

This sensor measures water droplet volume and overall water quantity using an array of exposed parallel wire traces. It provides a smooth conversion between the physical water volume and an analogue output signal.

Broad microcontroller compatibility

The module connects directly to microprocessors and logic circuits, offering excellent flexibility for makers. It is fully compatible with Arduino controllers, STC single-chip microcomputers, and AVR single-chip microcomputers.

Compact and efficient design

Engineered to be smaller and smarter than standard alternatives, this module features high sensitivity with low power consumption. Its compact, portable form factor makes it easy to position in tight spaces.

Durable FR4 construction

Built using a double-sided tinned FR4 production process, the sensor board is designed to withstand moisture exposure. This ensures reliable electrical contact across the exposed sensing traces.

Ergonomic semi-lunar recess

The board features an anti-slippery, semi-lunar recess designed for comfortable and secure handling during installation. This humanised design detail prevents accidental slips when positioning the sensor.

Technical specifications

The module operates at DC 5V and features an analogue sensor type with a dedicated 40mm x 16mm detection area. It is rated to operate in environments with 10% to 90% non-condensing humidity.
