Measure N, P, K, pH, Temperature, Electrical Conductivity, Soil Moisture, and Air conditions with automated pump control. Built by United Software Solutions in Dhaka.
Comprehensive sensor suite with secure cloud and actionable automations.
N, P, K, pH, Soil Temp, EC, Soil Moisture, Air Temp, Humidity, Pressure.
Timestamp every reading for reliable analytics and irrigation scheduling.
Pump turns ON/OFF based on soil moisture threshold with manual override.
Robust EC front‑end with AC excitation to reduce electrode polarization.
Secure APIs, device management, and analytics for farms of any size.
Auth for Admins, Users (Farmers), and Technicians built‑in.
The pump is automatically ON when Soil Moisture is below your threshold. You can toggle automatic mode and simulate moisture with the slider.
// Pseudo‑logic
if (auto && soilMoisture < threshold) pump = ON; else pump = OFF;
// Manual override and safety interlocks can be added as needed.Compact, weather‑resistant enclosure with modular probes.
