  • The IoT cloud sensor is a series of sensors based on cloud platform application technology, intelligent measurement, monitoring technology, clock and environmental parameters (temperature, humidity, location, etc.). It is not only featured in wireless transmission, but also has unique remote management functions such as data measurement, threshold setting, clock synchronization, measurement time setting, acquisition cycle setting, alarm setting, interference detection, software update and so on. The product is upgraded from a single measurement to the function of measurement, monitoring, judgment and alarm. It is very suitable for measurement, monitoring and state judgment in the industrial field.
