Other Parts Discussed in Thread: TIDA-00220
Q1:此demo的接近传感器与环境传感器背靠背布设,这意味着两个传感器处于独立的两个环境,环境传感器并没有发挥出最优的作用。能否将两个传感器布设在PCB的同一面?
Q1: The proximity sensor and the environment sensor of this demo are laid back to back, that means the two sensors are in two separate environments, and the environment sensor does not play an optimal role. Is it possible to lay both sensors on the same side of the PCB?
Q2:若两个传感器布设在同一面,两个传感器会同时检测到人体,会不会导致人体检测失效?
Q2: If two sensors are deployed on the same side, both sensors will detect the human body at the same time, will it lead to human body detection failure?
Q3:若FDC1004驱动两对差分传感器时,接法是不是ch1&2组成差分传感器,并分别采用shld1&2作为屏蔽。ch3&4组成差分传感器,并分别采用shld1&2作为屏蔽。
Q3: If FDC1004 drives two pairs of differential sensors, is the connection method ch1&2 to form a differential sensor and use shld1&2 as shield respectively. ch3&4 to form a differential sensor and use shld1&2 as shield respectively.
Q4:FDC1004的输入低通滤波器会对电容测量造成影响吗?RC参数选取需要注意什么?
Q4:Does the input low-pass filter of FDC1004 affect the capacitance measurement and what should I pay attention to when selecting the RC parameters?
Q5:环境交变磁场峰值1000uT,有效值330uT,频率85kHz,该系统还能正常工作吗?
Q5:Can the system still work properly with an ambient alternating magnet field with a peak value of 1000uT, an RMS value of 330uT and a frequency of 85kHz?
