The Dragino SPH01-LB LoRaWAN Soil pH Sensor is a crucial tool for modern agriculture, designed to accurately measure soil pH and temperature. This data is vital for assessing soil acidity or alkalinity levels, enabling farmers to tailor their cultivation strategies. Integrated with Telemetry2U, it offers detailed soil analysis, aiding in the enhancement of crop growth and soil health.

Robust and Reliable Sensor Technology: Constructed with a Solid AgCl reference electrode and a pure metal pH sensitive electrode, the SPH01-LB delivers high accuracy and stable pH readings. Its durability is evident in its design, allowing it to be buried in soil for extended periods, making it an ideal match for the long-term monitoring capabilities of Telemetry2U's platform.

Extended Connectivity and Power Efficiency: Utilising LoRa wireless technology, the SPH01-LB ensures long-range data transmission at low data-rates, providing ultra-long range communication and high interference immunity. This efficient power usage, combined with Telemetry2U's IoT solutions, makes it a sustainable choice for widespread agricultural applications.

User-Friendly Configuration and Longevity: The sensor supports BLE for easy configuration and wireless OTA updates, enhancing user experience. Powered by an 8500mAh Li-SOCI2 battery, it promises up to 5 years of continuous operation, aligning with Telemetry2U's commitment to providing long-term, reliable IoT solutions.

Simplified Connectivity and Registration: Each SPH01-LB comes pre-loaded with unique LoRaWAN registration keys for effortless setup. Once registered to a local LoRaWAN server, it automatically connects upon power-up, seamlessly integrating with Telemetry2U's platform for real-time soil pH monitoring.
