Power : dc6v(AC220V), comsumption : < = 0.5m w with 4 pieces of alkaline battery it can work for 2 years based 300 sensor times/day, sensor distance : 15-30cm after checking in factory accourding to standard inductive board , can self adjust after installation around 10-15cm, suitable water pressure : 0.1-0.6mpa , the temperature of environment : 0.1-45` c, pipe diameter : g 1/2"(DN15) , 4 aa size batteries not included. note that sensor faucets do not have simultaneous hot ; cold handles/knobs, so they are usually installed to be used with cold water only, or with an optional mixing valve, which fits under the sink/wash basin and connects to the hot and cold water source, and has a set control to proportionate the hot ; cold water into one source for the faucet to use. The "no-touch" advantage eliminates a major source of contamination of germs and is therefore hygienic to use .it's huge water-saving, dual power (Battery Or AC Mains Plug-In) sensor faucet with automatic turn-on ; shutoff upon removal of hands from the sensor proximity. All mechanical and electrical components are contained in one covered controlling box to be fixed below the wash basin for easy installation.operating temperature: 0-75 degree celsius. Can be powered with 4 aa alkaline batteries (Not Included) or 220volts ac mains electrical outlet. For best long lasting results use duracell aa size batteries.
