Introduction to the characteristics of LoRa environmental sensors

1. What is a LoRa Environmental Sensor

LoRa environmental sensors refer to LoRa nodes equipped with environmental sensors, such as temperature sensors, humidity sensors, air pressure, indoor air quality sensors, etc. However, unlike traditional environmental sensors, LoRa environmental sensors will collect data It is sent to the LoRa gateway through the LoraWan/LinkWan protocol, and finally sent to the server.

Since LoRa environmental sensors use LoRa technology to send data, this also determines that their networking is simpler than traditional sensors.

For example, assuming that the application scenario is a smart farm, when the farm covers a large area, the transmission distance of LoRa technology in urban areas is several kilometers, and the transmission distance in suburbs is more than ten kilometers, while traditional data transmission technologies such as Wifi only have a few kilometers. Therefore, when networking, the number of LoRa gateways that play the role of data transfer can be relatively small, and if Wifi technology is used, it may be necessary to configure hundreds of times more routers.

Second, the power consumption of LoRa environmental sensors

Because the LoRa environmental sensor adopts LoRa technology, the power consumption is very small. Even individuals who develop their own MCUs can achieve lower power consumption.

If the manufacturer has already designed the MCU and sensor for low power consumption, and provides matching optimized embedded software, the power consumption can be even lower.

3. Personalized parameter setting of LoRa environmental sensor

LoRa environmental sensors support users to personalize parameter settings according to actual application needs.

Fourth, the special features of LoRa environmental sensors - need to select frequency bands

When purchasing a LoRa environmental sensor, special attention should be paid. A product often has different models to support different frequency bands. You need to choose a LoRa environmental sensor according to the frequency band you actually use.

The above is an introduction to the LoRa environmental sensor, which involves what is the LoRa environmental sensor, power consumption, personalized parameter settings, volume, and frequency band used. I hope it will be helpful for everyone to understand this technology.
