  The Dragino NSPH01 is a **NB-IOT soil ph sensor** for IoT of Agriculture. It is designed to measure the soil PH and soil temperature, so to send to the platform to analyze the soil acid or alkali level. The probe is IP68 waterproof.
  NSPH01 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 NSPH01 probe can be buried into soil for long time use.
