From the answers from a previous question, the Therapy adherence resistive monitor NHS3152 will be able t use the resistive network sensing-interface to measure impedance using no battery (for either sensor or tag).
This is what i want to acheve -
Hello,
Both the NHS3152THADADK and NHS3152TEMOADK kits can be used.
The NHS3152TEMOADK kit has no switches, you can solder pins or the resistance directly to the board.
The THA kit has switches connected to the analog pins, which they don't need, but can be easily disconnected or even cut off completely.
Both boards have a battery holder, so both passive and active operation can be tested.
For the operation without a battery, the measurement only takes place when the tag is in the NFC field. In the case it is already battery-powered, the difference will be that the measurement will already be done to be read out by phone.
You may implement your custom mobile development according to your needs and the structure of your data.
Hope it helps!
BR,
Ivan.
