It never rains in Southern California? True. San Diego sees an average of 300 sunny days a year. And it’s a hot one today. Good thing that the next-generation Bosch sensors are multi-talents. Once installed, they measure not only movement, but also temperature and humidity. The latest sensors can even measure air quality. They have the potential to turn every smartphone into a mobile weather station, with which a home’s indoor climate can be precisely controlled.
