First, what are the materials of the induction faucet
Generally brass faucets are more cost-effective. The faucet body is generally cast with brass, and the surface is chrome plated after grinding and polishing. The coating of the faucet body can generally pass the neutral salt spray test, and there is no rust phenomenon within the specified time limit, and the coating should ensure that it will not flake off for a lifetime.
1, confirm the purchase of the main column basin, platform basin, under the basin are several holes, do not have to worry about the hole distance, are uniform size.
2. Confirm with the dealer whether the imported ceramic raft core is installed in the brand faucet. After the appearance of the phase, pay attention to the finish of the surface, to touch whether there are burrs, to see whether there are tracholes, cracks, oxidation spots, etc. Then the faucet handle up and down gently move around, such as flexible and not loose, no heavy feel can be bought.

Second, what is the principle of the induction faucet
The sensor faucet is based on the principle of infrared reflection. When we put our hands in the area, the infrared will feel that there are items blocking the infrared receiving tube, and then after the processing signal of the microcomputer, the faucet will automatically open, and the water will automatically flow out, and the water valve of the faucet will automatically cut off water after the hand is extended back. It is very convenient when using.
It can be seen that the induction faucet is operated using the infrared reflection principle, in addition, the induction faucet must pay attention to the material when buying, the different characteristics of the material and the different functions are different, it is recommended that people choose according to their actual needs.
