   * The **DHT11** sensor is a low-cost digital **temperature and humidity sensor** that is commonly used in various applications such as home automation, weather stations, and HVAC systems. The sensor uses a capacitive humidity sensing element and a thermistor to measure the surrounding air's humidity and temperature.

-  * **An optocoupler relay module** is a device that uses an optocoupler to isolate the input and output circuits of a relay. An optocoupler, also known as an optoisolator, is a semiconductor device that uses light to transfer electrical signals between two isolated circuits.
+  * This **Relay module** with 2 5V channels is used to take control of devices in the house that operate at high voltage. It can be easily controlled by a microcontroller and is compatible with Arduino.

+===== Conclusions =====
+A module has been implemented that registers the temperature and detects movement in a room. Depending on the presence/absence of the person in the room, the program switches to manual or auto mode.
