River-Level Monitoring with ESP32 and GSM: A Monsoon Design Sketch
How I'd build a low-cost river-level node for Assam's monsoon: an ultrasonic sensor on a bridge, an ESP32, a GSM link and SMS alerts on rate of rise. A local supplement to official flood warnings, not a replacement.
10 Final-Year IoT Project Ideas for Engineering Students in Assam
Ten ESP32 project ideas for a final-year engineering project in Assam, each with a real problem behind it, the core parts, and the one detail that lifts it above a copied tutorial.
IoT for Assam Tea Gardens: Soil, Weather and Pest Alerts on a Budget
What a small sensor network can realistically do for an Assam tea garden: soil moisture and pH checks, weather logging over GSM, and alerts that tell you when to scout for pests, not magic pest detection.
ESP32 Deep Sleep Modes and Wake Sources: A Power Optimization Guide
Reduce ESP32 current consumption from 240mA active to under 15μA using deep sleep, RTC memory, and timer or GPIO wake sources.
How Much Does IoT Hardware Prototyping and Development Cost?
A budget breakdown of IoT product development stages: components sourcing, custom PCB design, firmware engineering, and cloud infrastructure.
Best Practices for MQTT Telemetry on Low-Power Microcontrollers
Optimize your MQTT payload sizes, Quality of Service (QoS) levels, keep-alive frames, and deep sleep cycles for efficient IoT devices.
