If the radar needs to be fitted with an enclosure, the enclosure must have good wave- mission characteristics in the 24 GHz band and must not contain metals or materials that have a shielding effect on electromagnetic waves; This product needs to be installed in a suitable environment, if it is used in the following environment, the detection effect be affected: -There are non-human objects with continuous movement in the sensing area, such as animals, continuously swinging curtains and large green plants directly facing the wind. The presence of large strong reflective planes in the sensing area, strong reflective objects are directly in front of the radar antenna cause interference.When wall mounting, external interference factors such as air conditioners and electric fans on top of the room need to be considered. Power supply considerations, power supply input voltage of 3.0V ~ 3.6V, power supply ripple within 100 kHz without significant peaks, this program is a reference design, users need to consider the corresponding ESD and For interface surge and other electromagnetic compatibility design.<br><br>Frequency: 24G-24.25GHz Modulation mode: FMCW Detection distance: 0.75~6m adjustable Detection angle: ±60° Power supply: 3.3V(Typ.) Current: ~50mA Output Serial Level: 3.3V Sweep bandwidth: 250MHz Ambient Temperature: -40°C~+85°C Data format: Serial ASCII output/high and low level 3.3V& Package: Default with pins Colour:blue Material:plastic+metal<br><br>Package Contents: 1 x induction module<br><br>Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
