Portable ISV1101 high-precision level 12 monitoring sound level meter

1、 Product Overview:

With the development of technologies such as the Internet of Things and smartphones, acoustic measurement equipment should also move towards intelligence, networking, and IoT. The wireless IoT methods for mobile devices mainly include Bluetooth, ZIGBEE, WIFI and other technologies. With the popularity of WIFIThe department is vigorously promoting WIFI technology, and more and more devices are adopting WIFI technology as wireless IoT.The iSV1101 sound level meter sends the measured noise data through WIFI, and the receiving device can be selected from smartphones, tablets, laptops, and desktop computers. The processing power of these devices can be used for calculation and analysis, with flexible functions and matching. The instrument, when combined with PC or mobile software, can achieve functions such as total value analysis, statistics, and spectrum analysis.Note: PC and mobile software are provided separately
