FAQ
What WiFi modules do you use?
I commonly use ESP32 or ESP8266, but I can work with other WiFi-enabled microcontrollers if required.
Can you develop the firmware as well?
Yes. I provide complete embedded firmware for sensor reading, control logic, and WiFi communication.
Can the system control relays, fans, or heaters?
Yes. I design relay or MOSFET-based control circuits for HVAC, fans, heaters, and other loads.
Does it support cloud integration?
Yes. I can implement MQTT, HTTP, or cloud platform integration if needed.
Can it be battery powered?
Yes. I can optimize the design for low power operation if battery use is required.
