BillHo:
Yes, you can use One Wire Digital Temperature Sensor - DS18B20
Measures temperatures from –55°C to +125°C (–67°F to +257°F)

Since Cree CXB3590 COB lights is best operate at 85°C, so DS18B20 more appropriate and less parts for youe project.

Thanks so much. So I would just epoxy the digital sensor directly onto the ceramic LED plate so it is in direct contact with the LED (and not measuring ambient air?

thanks so much BillHo and Paul__B :slight_smile: really appreciate the fast advice
