Dragino LSPH01



IP68 rating



The Dragino LSPH01 is a LoRaWAN soil pH sensor for IoT of agriculture. It is designed to measure the soil pH and soil temperature, and for analyzing soil acid or alkali level. The probe is IP68 waterproof.

LSPH01 probe is made with a solid AgCl reference electrode and pure metal pH sensitive electrode. It can detect soil pH with a high accuracy and stable value. The LSPH01 probe can be buried into soil for long-term use.

The LoRa wireless technology used in LSPH01 allows the 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.

LSPH01 is powered by an 8500 mAh Li-SOCI2 battery and is designed for long-term use up to 5 years.

Each LSPH01 comes preloaded with a set of unique keys for LoRaWAN registrations. Register these keys to local LoRaWAN server and it will auto-connect after powered on.

What is pH? Why is it important to measure?

pH Measurement is used in a wide variety of applications: agriculture, wastewater treatment, industrial processes, environmental monitoring, and research and development. pH is a measure of the Acidity or Alkalinity of a Solution. The pH value states the relative quantity of hydrogen ions (H+) contained in a solution. The greater the concentration of H+ the more acidic the solution and the lower the pH. In this relationship, pH is defined as the negative logarithm of hydrogen activity.
