IoT sensors and monitoring on ESP32/Arduino

We work as a team. We build and set up a monitoring system on ESP32 or Arduino microcontrollers. The sensors measure temperature, humidity, light or voltage, and the data goes over Wi-Fi to a server or an MQTT broker. You view charts in Grafana or a simple web page, and important events arrive in Telegram. On-site visits: Almaty. We install equipment on site only in Almaty and do not serve other cities on site. Configuration, firmware and remote diagnostics can be done across Kazakhstan.

  • Choice of sensors and a controller for your task, with a shopping list and supplier prices
  • Assembly and wiring of ESP32 or Arduino with temperature, humidity or other sensors
  • Firmware in C++ in Arduino IDE or PlatformIO, sending data over MQTT

The service name is added to the message for you.

This is a starting price; we give the final amount before work starts. USD is approximate.

What is included

  • Choice of sensors and a controller for your task, with a shopping list and supplier prices
  • Assembly and wiring of ESP32 or Arduino with temperature, humidity or other sensors
  • Firmware in C++ in Arduino IDE or PlatformIO, sending data over MQTT
  • A Grafana dashboard or a simple chart page on your server
  • Telegram alerts when readings go beyond limits we set together
  • Installation and testing on site in Almaty, remote setup for objects in other cities where the client has installed the equipment
  • A document with the wiring diagram and a maintenance guide

Who it is for

For warehouses, greenhouses, cafes, production sites and private owners who want to know the state of a room or equipment without walking round it all the time. It does not fit if you need a certified industrial system with a full guarantee, for example for critical safety processes.

Not included

To avoid surprises, here is what the base price does not cover and what is discussed separately:

  • The sensors and equipment themselves, which the client buys from the shopping list
  • Industrial certification and dust or moisture protection to IP standards, if the site requires it
  • 24/7 monitoring with a duty person and response to emergencies
  • Physical work at sites outside Almaty: we do not carry it out in person

FAQ

After payment you receive the rights to the firmware, schemes, configuration and documentation we delivered. The ESP32 libraries, Grafana, Mosquitto and other open components stay under their own licences, and we list them. The data from your sensors belongs to you.

The price includes two rounds of revisions after the system starts: thresholds, polling intervals, alert texts and the dashboard look. Adding new sensors or new logic is paid separately and agreed in advance.

Usually 7 to 14 working days from the moment the sensor list and the installation point are agreed. Buying the equipment can take extra time, so it is best to count from a confirmed order.

A description of the site, what needs to be measured and how often, and where Wi-Fi is available. We also need access to the router or network on site and, if you have one, a server or VPS for the data. Photos of the room or plot speed up the choice of sensors considerably.

If the connection drops, the ESP32 keeps the latest readings in memory and sends them when the network returns, within the memory limit. For important points we recommend a UPS for the router and a backup link. We check Wi-Fi coverage on site before the equipment is bought.

Yes, a server or VPS is needed to store the data and run the dashboard, either one you already have or one you order separately. We set up the Mosquitto MQTT broker and Grafana, and limit access to them with passwords and certificates. Hosting costs are not part of this service.

Yes, relay control can be added, for example for watering or ventilation, but with safety limits and confirmation. Connecting the 220 V mains is done by an electrician, and we do not take on that kind of wiring without the right to do it. Control commands can be sent through Telegram.
