The PCB is the wireless (outside) sender unit for an inside/outside thermometer. I want to create a temperature probe from this PCB so that I can measure a temperature in a very specific place. I need help identifying the temperature sensor component on the PCB. I have had no luck pinning it down with freeze spray. Maybe it's the pair of transistors?

Following on from the accepted answer (thanks!), I tried moving the component out into a probe.
Temperature agrees with my current wired solution.
