This article introduces the functional program and IC selection of the smart sensor faucet program development; it is the controller that controls the infrared sensor device to start the faucet through the microcontroller chip. It is a newly invented high-tech product, which is widely used in hotels, guesthouses, office buildings and other places, which is conducive to saving water and resources for enterprises, while being more environmentally friendly.
Smart sensor faucet
Working principle
It uses the principle of AC power or DC power, and uses infrared induction. In the sensing area, water is supplied when the hand is extended, and when the hand is removed from the sensing area, the water stops running. The switch is automatically completed by the sensor without touching the tap, which can effectively avoid cross-contamination. This machine is controlled by the NY8A050D model of Jiuqi MCU. The appropriate sensing distance is determined according to the shape of the pool, without manual adjustment. It also has a 1-minute overtime flushing and water stop function, which can avoid waste of water resources due to foreign objects in the sensing range for a long time. The DC power supply uses alkaline dry batteries (6V, 3V, 4.5V), and has a built-in filter to prevent impurities from entering the solenoid valve, easy to clean, beautiful in appearance, and strong in structure.
Features of MCU
1. Single-chip selection: the NY8A050D SOP8 chip of Taiwan-based Nine-Qi MCU is used;
1. Infrared induction: automatic intelligent control, sensing infrared water to prevent water waste;
2. Single-chip micro-controller control: adjust the parameters of the single-chip microcomputer program, and adjust the amount and time of water output according to the actual use of the user;
3. Easy installation: install directly on the water outlet;
4. High water-saving rate: as long as the hand is removed, the water will stop.
