NBIOT/LTE-M Air Monitor
1. Introduce
This NBIOT/LTE-M1 Air Monitor is equipped with the ability to transmit temperature, humidity, light intensity, CO2 equivalent concentration, and TVOC to the network via SIM7080G. This air monitor is powered by internal 18650 lipo battery charged by solar panel.
It is designed to operate for extended periods with the solar panel to charge the battery and enter a low-power state.And then transmit the data via the NBIOT/LTE-M network, so user can monitor the field status or have them recorded for long-term analyze.
Model：NBIOTLMAM

6. Transmit the detection data to Thingspeak
6.1 Thingspeak
To transmit the data to your Thingspeak channel, it has to create a new channel and get the APIKEY information. Then replace the APIKEY in the code with yours.
- sign in or sign up for ThingSpeak
If you already have an account, log in and enter the password, otherwise click Create one to register.
- Create new channel
Select "Channel --> My Channels".
click "New Channel".
Write the name and field information.
Click Save Channel to create successfully.
