Hello Sagar,
Its dependent on what you want to do with that baseline capacitance. what is your end goal or application here? If you need the measure an absolute number for capacitance and then make a decision, neither are good for this. I would check…
Jim,
We will look at the FDC2214, but please note that even with water,they got different readouts!
This bring me to think that the problem is with the setting or the reading
OK, so the enable bits that you set are only to output the error flags in the measurements. I confirmed with the team and the FDC2214 does not support the amplitude H and L flags in the status register. So the best way is to just read the data and parse…
Other Parts Discussed in Thread: FDC2214 , FDC1004 I want to use FDC2214 (or FDC1004) in medical application with close proximity to human skin at all the time.
Do you have any data on (adverse) health effects of such configuration? If not, can you…
Hi Yaita-san,
There is a JSON file which shows the calculation. If you used the default directory to install the GUI, the file can be found here: "C:\ti\Sensing Solutions EVM GUI-1.8.8\PC GUI\server\assets\device\fdc2214\register.json"
The relevant…
Hello Bhupendar,
Inductive sensing technology (LDC1000, LDC1312) is used to detect the presence of metal objects and is not a good fit to detect the presence of humans.
Capacitive sensing is more suitable to detect the presence of humans. Please have…
- can we use our own sensor as proximity sensor to replace bottom 1 on the EVM? We need 2 proximity sensor for this project.
- since we target to detect human hand only single side of PCB proximity sensor, our sensor is PCB, one end connect to INX(top…
Hi Janine,
You may set the Fin divider to either 1 or 2 for your sensor frequency. This is not set incorrectly.
Fsensor and Fref should absolutely not be the same. The equation below is taken from the FDC2114's datasheet:
The FDC2214 has 28 bits…
Abhishek,
I am sorry I misunderstood the induction loop and inductive sensor.
Yes, inductive sensor can definitely be used in this application. However, the challenge might be to get enought eddy currents (coupling) in the target (car in this case…
Other Parts Discussed in Thread: FDC1004 , FDC2214 The FDC1004 allows use of the Out of Phase technique for robustness due to any hand interference. The example frequently given is a coffee maker. Suppose I now want to use salt water (conductive) in my…
