IoT Development

Software and hardware solutions that enable devices to connect to the internet and exchange data.

ARCHITECTURAL OVERVIEW

How HTech Labs delivers IoT Development

Bridging the physical world with cloud software requires hardware-grade reliability, low latency, and fail-safe protocols. With a portfolio of 25+ deployed IoT implementations, HTech Labs architects complete end-to-end IoT systems — from custom microcontroller firmware (ESP32, Arduino) to cloud MQTT message brokers and mobile/web control interfaces.

Architecture & Implementation FAQs

Q:

Which microcontrollers and wireless communication protocols are supported?

Our embedded hardware engineering team works with ESP32 dual-core, ESP8266 NodeMCU, Arduino UNO/Mega, STM32, and LoRa transceivers, communicating across MQTT pub/sub, Blynk Cloud, Telegram Bot webhooks, and direct MySQL database transactions.

Q:

Can HTech Labs handle both hardware PCB/sensors and the cloud web dashboard?

Yes. We deliver complete end-to-end IoT engineering: sensor calibration, opto-isolated relay drivers, custom enclosures, reliable C/C++ firmware with local flash fallback, paired with responsive web telemetry dashboards and mobile app alerts.
