This is through the infrared reflection principle, when the human hand or body part of the infrared region, the infrared emission from the infrared emitting tube due to human hand or body block block reflected to the infrared receiver tube through the integrated circuit microcomputer processing The signal is sent to the pulse solenoid valve, the solenoid valve receives the signal and then open the valve spool according to the specified command to control the head water; when the human hand or body leave the infrared sensing range, the solenoid valve does not receive the signal, the solenoid valve spool through the internal spring Reset to control the water shut down.
Infrared sensor role
Infrared sensor actually a lot of role, although we may not hear a lot. For example, in the cold winter can effectively prevent freezing pipes, the system automatically into the digital intelligent control system for quick and accurate adjustment of time delay. Only a few seconds you can change the program parameters, intelligent fuzzy control based on the number of people and the waiting time to achieve the best washing results.
Infrared sensor installed
Groove-type open beta water-saving device is installed in the inlet through a solenoid valve on the original automatic tank, the installation of infrared sensors in the toilet stool slot or the entrance of the urinal at the ceiling, the infrared sensor to automatically detect the scene, the infrared sensor to a control box will detect the signal, the microcomputer control box issued a command in the program after the booking process, control the solenoid valve into the automatic water tank for flushing, when someone into the toilet, the infrared sensor will start the above operation, if no one Into the public toilets, pressing the entire system will, will not be washed, so this will achieve the automatic management of health and water-saving effect.
