5. Production Guide

The storage conditions for the module after it has been shipped are as follows:

1. The moisture resistant bag must be stored at a temperature below 30℃, and under a relative

humidity below 85%.

2. The shelf life of dry packed products is 6 months following the packaged date important

information.

3. All line workers must wear anti-static wrist straps and anti-static clothing throughout the entire

production process.

4. It is strictly prohibited to allow a module to come into contact with water or other contaminants

during operations.

8. How to connect cloud platform

8.1 Wi-Fi Connection

In the first time of power on the devices, it would be set in ap mode and you can connect your pc/mobile phone to its wifi signal. It would be like Dusun_******, where the ****** are the last 6 bits of the devices’s MAC address. For example, the one in my test is Dusun_807F69

Then type in the ip 192.168.4.1 to log in the devices’s wifi, fill in the SSID and password of your router, then press

Save button. Your devices would connect to your router automatically.

8.2 MQTT configuration

Configure MQTT credentials of your server as listed.
