Infrared sensor enables temperature readings via smartphone app

10 October 2015

Calex Electronics' new PyroNFC is a small, low-cost infrared temperature sensor that lets engineers and machine operators use a smartphone app to check temperature measurements.

The IP65 sealed PyroNFC sensor measures the temperature of surfaces in industrial processes without contact, and at just 29mm in length, it is the smallest sensor that Calex has ever produced. It has a linear voltage output for connection to industrial process instrumentation, and an open drain alarm output that can be used simultaneously. 

By touching an NFC-enabled smartphone against the back of the sensor, the user can read the measured temperature with the free app. The reading updates continuously while the phone is touching the sensor. 

With the app, the user can also read or write configuration parameters including the emissivity setting, which allows an accurate reading on a variety of materials. There is no need to power the sensor to do this: hundreds of sensors can be configured in minutes on a bench-top without connecting a single wire or cable.
