1. Introduction

Avolta is a wireless, battery-operated, Natural Gas leak detector. It embeds the

Foxberry CH4NB sensor from eLichens, a cutting-edge NDIR (Non-dispersive

Infrared), dual-channel sensor designed specifically to detect Methane, and only

Methane. The sensor ultra-high selectivity has been validated by the Chicago Gas

Technology Institute (GTI) and prevents the generation of false alarms by volatile

hydrocarbons. The Foxberry CH4NB sensor is based on eLichens’ patented

technology including a proprietary IR micro-source, patented optical design and

advanced signal processing algorithms. It provides the lowest power consumption on

the market and is a key differentiator for battery-powered safety products. Avolta leak

detector is battery-powered, and has an autonomy of more than 10 years, with the

sensor constantly ON and a LoRaWAN heartbeat message sent every 8 hours.
