1. In the purchase of as far as possible to choose a reliable sensor lamp brand, if it is an infrared sensor lamp, try to choose a hemispherical probe, this kind of probe sensor lamp for the human body detection area is wider and more reliable. To make the luminaires more beautiful, many manufacturers do not use a hemispherical probe design, so the sensing area is narrow.
2. If it is only used indoors, do not pursue the induction distance and buy a microwave induction lamp. If the sensing distance is far, causing the sensing area to increase, the lamp is likely to light up when you don't need it, causing false touch induction. Therefore, when we buy, we must choose the appropriate sensor lamp type according to the occasion.
