Here is another iPhone compatible infrared thermometer that can detect fever to make sure only healthy people can enter your place of business. The OZS Bluetooth Doorbell Thermometer doesn’t require any contact to get a reading. It can read temperature from 2 to 6 inches in a second. Upon detection of any temperature above 99.5F, a flashing red light and audible alarm will go off.
The OZS Doorbell Thermometer has a digital display to show the results. Users will be able to view historical data on their iOS or Android device. As the name suggests, this also works as an electronic doorbell.[where to get it]
