LoRaWAN soil PH sensor

1.1 Product Overview

The lorawan soil PH sensor independently developed by our company has the characteristics of small size and integration, convenient transportation, carrying and installation, and can be dynamically adjusted at any time. The appearance, working conditions, safety requirements, functional requirements and communication requirements of the equipment can be adapted. Different measurement environments.

The product network transmission adopts a stable and reliable operator network, mature technology, stable transmission, strong signal and wide coverage. At the same time, the device supports timing data collection and active upload to the server platform.

1.2 LoRaWAN characteristics

• Transmission distance: up to 1km in towns, up to 3km in open suburbs

Working frequency: ISM frequency band including 433, 868, 915 MHZ, etc.

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

Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer the transmission distance.
