ABLIC upgrades battery-less water leak detection sensor
ABLIC Inc. upgrades its CLEAN-Boost energy-harvesting technology for the U.S. and EU markets. The battery-less drip-level water leak sensor now offers a communication range that is approximately 2× that of its predecessor and an expanded operating temperature range of up to 85°C from 60°C.
ABLIC said it first launched the CLEAN-Boost energy harvesting technology in 2019 to generate, store, boost, and transform microwatt-level energy into electricity for wireless data transmission. Since that launch, the Japan-market model earned positive evaluations from over 80 customers, and given increased inquiries from U.S. and European customers, the company obtained the necessary certifications from the U.S. Federal Communications Commission and the EU’s Conformité Européenne, confirming compliance with key standards.
CLEAN-Boost can be used in any facility where a water leak poses a potential risk. It uses microwatt energy sources to generate electricity from leaking water and transmits water signals wirelessly. The latest enhancements enable the sensor’s use in a wider range of applications and high-temperature environments, the company said.
Applications where addressing water leaks is critical include automotive parts factories with stamping processes, chemical and pharmaceutical plants, and food processing facilities as well as in aging buildings where pipes may have weakened or in high-temperature operations such as data centers and server rooms.
ABLIC claims the water leak sensor is the industry’s first sensor capable of detecting minute drops of water. It can detect as little as three drops of water (150 μl minimum). In addition, operating without an external power source eliminates the need for major installation work or battery replacement, making it suited for retrofitting into existing infrastructures.
The water leak sensor also helps reduce environmental impact by eliminating the need to replace or dispose of a battery. For example, the sensor has been certified as a MinebeaMitsumi Group “Green Product” for outstanding contribution to the environment.
ABLIC’s CLEAN-Boost technology works by capturing and amplifying microwatt-level environmental energy previously considered too minimal to use. It combines energy storage and boosting components, designed for ultra-low power consumption. The boost circuit operates at 0.35 V for the efficient use of 1 μW of input power. It incorporates a low-power data transmission method that optimizes the timing between power generation and signal transmission, ensuring maximum efficiency and stable operation even under extremely limited power.
The sensor features simple add-on installation for easy integration and sends wireless alerts to safeguard against catastrophic water damage.
The sensor technology is available as a wireless tag (134 × 10 × 18 mm with the main body measuring 65 × 10 × 18 mm), or sensor ribbons (sensor ribbon 0.5 m, sensor ribbon 2.0 m, and sensor ribbon 5.0 m), measuring 700 ×13 × 8 mm, 2200 × 13 × 8 mm, and 5200 × 13 × 8 mm, respectively. They can be connected up to 15 m.
