Dragino SPH01-LB/LS LoRaWAN Soil pH Sensor
Dragino SPH01-LB/LS LoRaWAN Soil pH Sensor (US 915 MHz band)
- IP66 Waterproof Enclosure
- IP68 rated for the Sensor Probe
- 8500mAh Battery for long-term use
- US 915 MHz band
- Ultra-Low Power Consumption
- Smart Agriculture Applications support
SPH01-LB/LS probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect soil’s pH with high accuracy and stable value. The SPH01-LB/LS probe can be buried into soil for long time use.
The LoRa wireless technology used in SPH01-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
SPH01-LB/LS supports BLE configure and wireless OTA update which make user easy to use.
SPH01-LB/LS is powered by 8500mAh Li-SOCI2 battery or solar powered + li-on battery it is designed for long term use up to 5 years.
Each SPH01-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
