RF430FRL152HEVM: no battery device could get power from RF

user6371202

Part Number: RF430FRL152HEVM
Other Parts Discussed in Thread: RF430FRL152H

Dear Sir,

Is it possible to build a temperature sensing without battery. It gets power when NFC scan and work to send SD14 ADC temp value. If the answer yes, do I need to modify the circuit?

Thanks,

Sean

Hello Sean,

yes, this is possible. Please see the following document:

This works also with RF430FRL152HEVM.

Also an App for Android Smartphones is available to read out the temperature:

Thanks, Helfried. I have another question about the temperature sensing. The schematics shows ADC0, ADC1, ADC2 connected to light sensor. How do I calculate the temperature?

Thanks,

Sean
