Application of LoRa-E5 radio module
LoRa-E5radio modulecan be used in conjunction with development boards. It gives them the ability to communicate over long distances (in open space the transmission range reaches up to 10 km). Moreover, it is characterized by high efficiency and low power consumption. It has aGrovecompliant connector, which allows for plug & play connection. The modules can be controlled via an AT command prompt issued over a UART connection. Grove LoRa-E5 will be the best choice for scenario expansion, device testing and IoT scenarios with very low power consumption such as smart agriculture, smart office and smart industry. It is designed according to industry standards with high sensitivity from -116.5 dBm to -136 dBm and output power from 10 dBm to 22 dBm.
