Temperature and humidity sensors on smartphones
Samsung with its Galaxy S4 took the lead last year by introducing the first smartphone to integrate temperature, pressure, and humidity sensors all on one device. Other device makers have since begun looking at the possibility of integrating more and more sensors onto smartphones.
Will the trend of integrating temperature and humidity sensors onto smartphones continue? “The use case of humidity sensors is not very impressive,” Bouchaud said. “There really isn’t anything interesting that has surfaced since the device was used in the Galaxy S4 for example.”
Still, device makers have made an effort to place sensors inside smartphones. “Since the first iPhone there have been new sensors in smartphones every year." Sometimes it's just a technology push, Bouchaud said. "There isn’t always real demand, and I’m not sure humidity sensors especially are going to stick,” he concluded.
We’ll see about that. Until then, here is a brief breakdown of Samsung’s Galaxy S4, which surprised many in the industry by including integrated temperature and pressure sensors on a smartphone device.

You'll never feel alone: Samsung's Galaxy S4 offers to be your life companion in this ad. A teardown on iFixit reports that GS4's sensors include an accelerometer, RGB light, digital compass, proximity, gyroscope, barometer, IR gesture, and temperature & humidity.
The Galaxy S4 new temperature and humidity sensor allows users to measure their current ambient conditions. Samsung’s app displays current ambient temperature and humidity and provides users with information as to how to augment their measurement capabilities. The presence of these sensors allows a user to track the evolution of conditions over the course of many hours and days, monitoring temperature and humidity changes along the way. The device runs measurements as a service in the background, and includes an accuracy index among its features. In addition to displaying the ambient temperature and humidity, the device allows for real-time graphs to arrange and display data over time. It features pinch-to-zoom control on the plots as well as portrait and landscape mode and the choice between °C and °F as units for measuring temperature.
