Soil pH Monitoring | Wireless soil pH monitoring kit for accurate acidity data

What is the Sensor Hub Solution for Soil pH monitoring? The RAK Sensor Hub Solution for Soil pH Monitoring Sensor is a high-precision, rugged, and scalable industrial soil pH measurement kit tailored for agriculture, research, and land management. It is part of RAKwireless’s Soil Monitoring Sensor Hub Solutions/Sensors and is designed to deliver real-time soil health insights for smart farming solutions. Based on the modular Sensor Hub platform, it integrates the industrial-grade RK500-22 Soil pH Sensor with reliable wireless connectivity over LoRaWAN technology or NB-IoT (CAT M1 / CAT NB2). Designed for continuous operation in harsh outdoor environments, the soil sensors for LoRaWAN are ideal for: Smart farming and precision agriculture Greenhouses, orchards, and nurseries Soil science research and remediation Soil management and environmental monitoring Aquaculture and wastewater treatment The Sensor Hub allows multiple sensors to be connected simultaneously, and extension cables or splitter accessories provide deployment flexibility across wide areas. Also, the SensorHub Solution with RK500-22 Soil Acidity Sensor is available in two variants: LoRaWAN-only LoRaWAN + NB-IoT Supports CAT M1 (higher data rates, lower latency) and CAT NB2 (ultra-low power, extended coverage), making it suitable for long-term, battery-powered deployments. Model Type Best For Connectivity Power Usage LoRaWAN-only Rural or low-power farms Long-range, low-power Very low LoRaWAN + NB-IoT Industrial or urban sites LoRa® technology or Cellular Moderate Note: When using the Sensor Probe IO with a connected wireless soil pH sensor, the Sensor Hub cannot be powered by batteries. Use the included DC adapter or add the Solar Battery Lite system. Why You Need the Sensor Hub Solution with RK500-22 Soil pH Monitoring Sensor?

Key Features of the Soil pH Monitoring Solution LoRaWAN technology / NB-IoT communication (based on selected model) Durable outdoor-ready design High accuracy and fast response time IP68-rated waterproof stainless steel probe DC power or Battery Lite with Solar Panel(optional) Measurement range 0–14 pH Accuracy ±0.05 pH Resolution 0.01 pH Response time with soil moisture above 30% less than 10 seconds Probe dimensions are 15 mm in diameter and 200 mm in length The cable length of the pH sensor is 5 meters (about 16.5 feet) Supports global LoRaWAN bands. Power & Connectivity: LoRaWAN or NB-IoT The Soil pH Monitoring Solution supports LoRaWAN for long-range, low-power deployments and NB-IoT for sites with cellular coverage or higher reliability needs. It can be powered by a DC adapter or the Solar Battery Lite system for off grid deployments. Data and Platform Integration This soil pH measurement device integrates with RAK Cloud, The Things Network (TTN), and ChirpStack for LoRaWAN workflows. Data can also be forwarded to third-party analytics tools for trend monitoring and farm management. The Sensor Hub lets multiple sensor modules share one uplink, simplifying deployment across field sites. Use Case Examples for Sensor Hub Solution with RK500-22 Soil pH Monitoring Sensor As part of a smart farming IoT sensor system, the soil pH measurement device adapts to a wide range of applications and addresses real problems with practical monitoring capabilities. Use Case #1: Precision Farming in Orchards Farmers use the wireless soil pH sensor to check field acidity across multiple orchard plots. The system gives them real-time updates right away, so they can adjust treatments on time. This leads to consistent fruit quality and healthier crop growth cycles. Use Case #2:Aquaculture Site Environmental Monitoring A fish farm uses the soil pH sensor to monitor pond-side soil conditions near banks, runoff areas, and treatment zones. The system provides wireless updates that help operators track environmental changes around the site and support better pond management decisions.
