With the continuous development of Internet of Things technology, LoRa (Low Power Wide Area Network) modules are widely used in various fields. This article will discuss how the LoRa module plays a role in remote weather monitoring projects, providing an efficient and reliable solution for the collection, transmission and analysis of weather data.


Remote weather monitoring plays an important role in fields such as agriculture, meteorological research and environmental protection. As a communication technology with low power consumption and strong long-distance transmission capability, LoRa has gradually been applied in weather monitoring projects.

2. Overview of LoRa technology:

Based on the characteristics of long distance, low power consumption and low data rate, LoRa technology is suitable for long-running wireless sensor networks. The LoRa module can cover a wide area and has excellent penetration, making it excellent in remote weather monitoring.

3. Application of LoRa in remote weather monitoring:

E22-400T33S UART module

E22-400T33S LoRa Wireless Module

[Product size]:25*40.5mm

[Communication distance]:16km

[Transmit power]:33dBm

[Carrier frequency]:410.125~493.125MHz

[Chip solution]:SX1268

[Introduction]:E22-400T33S is a wireless serial port module (UART) based on SEMTECH's SX1268, working at 410.125 ~ 493.125MHz (default 433.125MHz),TTL level output, compatible with 3.3V and 5V IO port voltage. Compared with the traditional SX1278 solution, it has a longer transmission distance, faster speed, lower power consumption, and smaller size; it supports functions such as air wake-up, wireless configuration, carrier monitoring, automatic relay. communication keys and sub-package length setting. Ebyte provides customized development services on it. An obvious advantage is that SX1268 covers wider frequency range.

Meteorological data collection: LoRa nodes can be connected to a variety of meteorological sensors, such as temperature, humidity, air pressure and wind speed sensors, to collect meteorological data in real-time.

Data transmission: Through the LoRa module, the collected meteorological data can be remotely transmitted to the base station or cloud platform to realize real-time monitoring and data sharing.

Geographical distribution: Multiple LoRa nodes can be distributed in a wide weather monitoring area to achieve full coverage and ensure data accuracy and integrity.

Low power consumption: The low power consumption characteristics of the LoRa module make it suitable for long-term operation, and can be powered by batteries to reduce maintenance costs.

Advantages of LoRa in remote weather monitoring projects:

Cost-effectiveness: The deployment and maintenance costs of LoRa nodes are low, which is suitable for large-scale weather monitoring networks.

Long-range transmission: LoRa technology can realize data transmission in a long distance, which is suitable for meteorological monitoring in remote areas.

Stability: The LoRa module has strong signal penetration capability and can maintain stable data transmission in complex environments.

Real-time data: Through the LoRa module, meteorological data can be transmitted in real-time to help with timely warning and decision-making.
