Climate control v3 Конфигурация v3.3

One of the most important tasks of a smart home is controlling and managing its heating. Of course, this is only the beginning. The next step will be automating ventilation and dealing with low and high humidity. We have combined these main issues for creating a comfortable climate in homes or elsewhere into one project called "Climate Control". With its help, you can easily start home automation, even with just one portable heater. Please note that this project has several variants of PCBs!

Climate PCB v3.2

The basic controller of the Smart Home project is great for beginners who want to learn how the system works. It displays all the capabilities but is rarely used in practice. This controller is suitable for small spaces where the devices are located close to each other. However, in practice, other printed circuit boards are often used, such as ClimatePlace, which are installed directly next to each device, such as heaters, vents, humidifiers, etc. Then, all the devices are combined into a single network.

Small board size: 92x92mm.

The fan control is done directly from the SelfFan board with a voltage of U=5V and Imax=200mA.

Usually, the fuse relay FuseHeat controls a contactor that disconnects power to other devices.

The temperature control sensor module SelfTemp can be placed directly on the board without being connected through a connector.

The printed circuit board allows for the connection of high-voltage loads, but please note:

To reduce resistance, the tracks that are switched to the relay must be additionally well tinned.
Over time, switching a circuit with a high current can cause contact burning, so it is better to use an SSR relay as it is noiseless and durable.

The fuse is installed in front of all devices. Its purpose is to break the circuit and prevent the coolant temperature from rising to a critical level in case the relay malfunctions (contact sticking, MOSFET burnout).

Универсально! Разработанная схема предусматривает как размещение на плату элементов, так и отказ от них. Например, Вы можете использовать только прямой цифровой вывод для соответствующего устройства или датчика и самостоятельно собрать исполнительную схему, либо же, Вы можете разместить на плате предложенные компоненты - блок реле, оптроны, транзисторы и т.п. и таким образом получить полностью готовый проект. Кроме прямых цифровых выводов, на плату добавлены дополнительные разъемы 5V, 3.3V, GND для питания внешних модулей.

Опасно! Напряжение 220В опасно для жизни и может вызвать пожар!

Принципиальная схема

Внимание! Предложенная схема является типовой и может быть модернизирована согласно Ваших предпочтений и требований. Вам необязательно использовать все компоненты указанные в схеме и подключать их! Аналогично, Вы можете использовать этот проект не по прямому назначению, заменяя устройства и компоненты на какие-либо другие.

ClimatePlace PCB v3.3 v3.2

Often, several heaters are used to heat a room, which are located at a distance from each other. The same applies to ventilation systems and humidifiers. That is why we created a more convenient and compact printed circuit board for this project. It has a built-in power supply and layout for easy connection of a fuse relay, a noiseless relay, and two heaters. Using such controllers in different parts of the house allows for gradually introducing smart heating without making global changes throughout the house. In addition, the load on the house's electrical wiring is evenly distributed, which reduces the risk of fire.

The board has the following features:

Compact size: 76x64mm.
Contains a compact power supply: HLK-PM01.
The power voltage is connected directly to the fuse relay with a maximum current of 10A.
Connectors are installed for connecting the noiseless SSR relay.
Connectors are installed for connecting two heaters in parallel.
Connectors are installed for connecting external relay blocks (for example, Universal B1) to control the ventilation and humidifier.
You can abandon the fuse and use its relay for direct heating control. To do this, you need to solder a jumper in place of the SSR-220V connector and change the heater controller settings from GPIO 4 to GPIO 13.
