Smart postbox detector /sensor with NB-IoT/LoraWAN module

1 Overview DY404 is a smart postbox detector, which can be used to detect the number of letters, post door status, fire alarm, or fall alarm; through the built-in NB-IoT module, information can be transmitted through the NB card to the cloud server. Users can observe status information remotely. The device has different versions and can support B1, B3, B5, B8, B20, B28 and other frequency bands. Due to the low power consumption algorithm, the internal battery can work for more than 3 years .
