1.All components(sensor,sircuit,pulse solenoid valve,thermostat and battery) are preset in tap body

 
2. Ware through the infrared sensor reflection principle, when the body of   the hand or a part of the body in the infrared region, infrared emission control for infrared Picks of the human hand or body to block reflection infrared receiver tube, through the integrated circuit within the microcomputer treated signal is sent to pulse solenoid valve, solenoid valve signal received by the specified command to open the water valve to control the head; hand or body when the body left the range of the infrared sensor, solenoid valve not receiving signal, the solenoid valve spool through the internal spring reset to control off the water
3.Cold and hot integration.It is a mixer with the cold water in the left turning and hot water in the right turning.

4.Avoiding bacterial mutual infection
Water saving(about 30%)
4*1.5vAAbatteries lasted 2years based on 300 cycles per day
