Other Parts Discussed in Thread: TIDA-00220
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: 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: 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：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: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?
