If the radar should be fitted with an enclosure, the enclosure must have nice wave-transmission traits within the 24 GHz band and must not ever involve metals or supplies that have a shielding impact on electromagnetic waves; This product should be put in in a suitable environment, if it is used in the ensuing environment, the detection effect could also be affected: -There are non-human items with continuous movement in the sensing area, resembling animals, continuously swinging curtains and big green plants immediately facing the wind. The presence of massive stable reflective planes within the sensing area, stable reflective items are directly in front of the radar antenna will trigger interference wall mounting, outdoors interference factors corresponding to air conditioners and electric fans on top of the room must be considered. Power supply considerations, energy delivery enter voltage of 3 ~ 3, power delivery ripple within a hundred kHz with out significant spectral peaks, this program is a reference design, users need to evaluate the corresponding ESD and For Apple interface surge and other electromagnetic compatibility design. Frequency: 24G-24 Modulation mode: FMCW Detection distance: 0~6m adjustable Detection angle: ±60° Power supply: 3(Typ.) Current: ~50mA Output Serial Level: 3 Sweep bandwidth: 250MHz Ambient Temperature: -40°C~+85°C Data format: Serial ASCII output/high and occasional level 3&OV Package: Default with pins Colour:blue Material:plastic+metal Package Contents: 1 x induction module Only the above equipment content, diversified item are usually not included. Note: Light reflection and diverse displays can cause the color of the object within the photo considerably various from the genuine thing. The dimension allowed error is +/- 1-3cm.
