Description Unit Watering is a capacitive soil moisture detection and irrigation control unit designed for smart plant cultivation projects. It integrates a soil moisture measurement plate and a water pump, allowing the system to detect soil humidity and control watering in one compact module. The measurement plate uses a capacitive design, which is more resistant to corrosion than traditional resistive moisture probes during long-term use in soil environments. Features Capacitive soil moisture measurement plate More corrosion-resistant than resistive moisture probes Integrated 5W water pump Supports soil moisture detection and irrigation control LEGO compatible holes Suitable for smart plant cultivation projects Specifications Specification Parameter Pump Power 5W Product Size 192.8 x 26.5 x 33.0mm Product Weight 94.6g Package Size 200.0 x 45.0 x 35.0mm Gross Weight 114.2g Interface Uses a HY2.0-4P Grove cable connection Supports water pump control and analog moisture signal output Applications Plant cultivation Soil moisture detection Smart irrigation Automatic watering projects Product List 1 x Unit Watering 2 x Water Suction Tubes 1 x HY2.0-4P Grove Cable (20cm) Other Content Unit Watering combines sensing and actuation in one module, making it convenient for building automated plant watering systems.
