LoRaWAN Soil NPK sensor
-
1.1 Product Overview
RK-3001-NPK sensor is a sensor based on LoRaWAN for data transmission. The sensor is suitable for detecting the content of nitrogen, phosphorus, and potassium in the soil, and judging the fertility of the soil by detecting the content of nitrogen, phosphorus, and potassium in the soil, so as to facilitate the customer's systematic evaluation of the soil.
It is suitable for paddy field, greenhouse cultivation, rice, vegetable cultivation, orchard nursery, gardening, flower and soil research.
1.2 LoRaWAN characteristics
1.Transmission distance: up to 1km in towns, 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.
1.3 LoRaWAN product advantages
1.Low cost, wide coverage, low power consumption, long life.
2.Consistent, stable and reliable.
3.Long transmission distance, strong signal, flexibility in deployment services.
4.Battery life and long service life.
5.A physical layer modulation technology, which can be used in different protocols.
6.Good security and confidentiality.
