Pune-based Proximal Soilsens Technologies bridges the gap between lab testing and the field with proximal sensors for real-time soil analysis.
Proximal Soilsens Technologies Private Limited, founded by Rajul Patkar in June 2017, has introduced two innovations: NutriSens and TerraPort. NutriSens is a device designed to detect soil nutrients within five minutes, offering instant recommendations for farmers.
TerraPort, a compact 100-gram portable device equipped with multiple sensors, enables farmers to traverse their fields, gather real-time data, and upload it via mobile for immediate insights.
“With just 30 minutes of training, anyone—including farmers, women, and students—can operate both devices. NutriSens is a lightweight, 50-gram, ultra-low-power device that runs on mobile phone power and has been validated by Tamil Nadu Agricultural University, achieving an impressive 80-90% accuracy compared to lab results,” explains Rajul.
Previously, the startup developed TerraStation, an IoT-enabled soil moisture sensor that continuously transmits data to the cloud for remote irrigation management. However, it was a fixed installation, collecting data only from a specific field. Recognising the need for a more mobile solution, particularly for small farmers, the company introduced TerraPort.
To monitor soil moisture profiles, farmers insert the device into the soil, enabling real-time data collection across multiple farms simultaneously. It functions without requiring electricity or batteries.
