RFM50 module series’ design is based on the high performance RF50 SoC chip, It include a CIP-51 core‘ MCU and 100mW transceiver. It operate at 433/470/868/915 MHz ISM band, comply with FCC, ETSI regulation.
The DWM-DF12LD use LoRaWAN communication and it detect smoke generated during fire in time and issue an alarm in time report the fire alarm information to the intelligent fire monitoring platform in real time.
The DWM-DF12LD Smoke Detector is based on photoelectric technology, which is more sensitive to detecting white smoke, black smoke and smoldering smoke that has not turned into an open flame. It can detect smoke generated during fire in time and issue an alarm in time; The wireless communication adopts the international standard LoRaWAN communication technology, which can support the global ISM frequency band, operates in the Class A low power consumption mode, and can report the fire alarm information to the intelligent fire monitoring platform in real time.
