Notice: If you're not familiar with LoRa wireless module, you'd better to buy two same frequency modules + antennas as you'll need two to transmit and receive data.
Description:
E32-915T20D is a 100mW wireless transceiver module, operates at 900~931MHz, based on original imported RFIC SX1276 fromSEMTECH. The module adopts LoRa spread-spectrum technology, which means the transmitting distance is much longer than before.
Widely used in various occasions: Meter Reading, Smart Home, Smart Agriculture, Smart Oil Field, Industrial Wireless Control, Environment Monitor, Temp/humidity Sensor and etc.
