Overview
PMM0618L is a reliable, and simple to set up interface converter that implements data exchange. LoRaWAN TO RS485 Converter converts the LoRaWAN signal into RS485 wireless signal which simplify the IoT installation and reduce the installation/maintaining cost. It allows the user to monitor and control RS485 devices and reach extremely long ranges. It provides ultra-long range spread spectrum communication, and high interference immunity while minimizing current consumption.
For data uplink, RS485-LN sends user-defined commands to RS485 devices and get the return from the RS485 devices. RS485-LN will process these returns according to the user-define rule to get the final payload to upload to LoRaWAN server. For data downlink, RS485-LN runs in LoRaWAN Class C and will forward the commands from LoRaWAN server to RS485 devices.
The LoRaWAN specification is a Low Power, Wide Area (LPWA) networking protocol designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks, and targets key Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.
It can be widely used in but not limited to the following applications
Applications
- Irrigation systems
- Smart metering
- Smart cities
- Smart phones detection
- Smart Buildings/ Building automation
- Home Automation Logistics
- Supply Chain Management
- Smart Factory
- Smart Agriculture
