Soil pH & Temperature Sensor – Global NB-IoT

Model NA-DG-069
Price on request
A buried probe that measures soil pH and soil temperature and reports both over cellular NB-IoT. Temperature compensation keeps pH readings accurate as the soil warms and cools, and the user can recalibrate pH in the field to maintain accuracy over time. It helps growers time liming and fertiliser application and detect acidification in fields, orchards and greenhouses where no LoRaWAN coverage exists. Several readings are batched into one uplink to stretch the 8,500 mAh battery, settings and firmware are updated over Bluetooth, and NARA tracks pH trends for every plot.
