Application Case：Remote multi-component greenhouse gas monitoring system based on Beidou short-message communication

Experiments: communication successful rate

Definition: data delay within 1 min is defined as successful

Test site: Ningbo China (29°47'53''N, 121°33'46''E)

Experiment 1：Semi-exposed platform

Success rate: 82.5%

Experiment 2：Open space

success rate: 92%

Conclusions

1. System power

HT8850: 100W

Communication: peak 17.5W for<0.3 secons="" duration="" per="" transmission="">

2. Two transmission modes were ultimately implemented

The first is a single-user mode, where each user has their own Beidou receiving module, and the processed data is obtained with high flexibility through a Raspberry Pi.

The second mode supports uploading Beidou data to the cloud, where multiple authorized users can access real-time data via a user-friendly web interface.
