​​​​Wi-Fi Kit/GPRS Kit/NB-IOT Kit

Kit series wireless module is used to expand the Wi Fi, GPRS and NB-IOT wireless network data transmission channels of the device. It is built-in device, which is connected to the device through TTL serial port. It has strong protocol compatibility and low dependence on the transmission environment. It also supports remote control, remote debugging and remote upgrade functions. It can quickly transfer the data to the cloud server, which can provide users with a complete monitoring solution with low cost, visualization and remote operation.
