Description
Overview
GAOTek explosion proof wireless NB-IoT pressure sensor for IoT uses a large-capacity lithium battery to provide a stable and reliable power supply for the product, enabling it to operate safely for more than 5 years(uploaded once an hour). The self-developed low-power system can not only provide users with on-site data through the LCD screen, but also upload data through the wireless module, and even graft the data to the user’s own cloud platform. The powerful control algorithm enables the instrument to have signal breaks, Transmission, working mode automatic switching, pressure fluctuation real-time alarm, one-click wake-up and other practical functions.
