LoRaWAN Smoke sensor Transmitter
-
Features
1. Transmission distance: up to 1km in towns and up to 3km in open suburbs;
2. Working frequency: ISM frequency band including 433, 868, 915 MHZ, etc;
3. Modulation method: based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS), with forward error correction (FEC) capability, proprietary patented technology of semtech;
4. Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer the transmission distance.Probe Parameters
