Common sensor types and what each one measures
Temperature, humidity, level, current, motion, gas and more: a plain guide to the sensors used in business IoT projects, what each measures, and what to think about when choosing one.

IoT device development
Connected devices from prototype to dashboard: sensors, firmware, connectivity and alerts that reach your phone.
I design and build connected devices that measure, control or report something, and the software that makes their data useful: dashboards, alerts and integrations.
What I build
- Monitoring devices for temperature, humidity, power, water level, motion and more, sending readings to the cloud.
- Control and automation: devices that switch equipment on and off by schedule, by rule or from your phone.
- Firmware for ESP32 and Arduino-class boards, written for reliability, with remote updates.
- Connectivity and networking: Wi-Fi, MQTT and HTTP connections, with the network set up so devices stay online.
- Dashboards and alerts: live dashboards, and SMS, email or chat alerts when a reading crosses a limit.
Built for unsteady power and internet
Every device starts as a prototype tested where it will be used, with your power, network and conditions. The firmware restarts by itself after load-shedding or a network drop, and stores readings while offline to send later.

IoT explained for business owners: devices, data and decisions
IoT means ordinary equipment that reports what is happening, like a fridge that sends its temperature to your phone. How it works in plain words, where it helps a business, and where it does not.
