HC-SR501 pyroelectric infrared (PIR) motion sensor. It is used in various alarm systems to detect a living object — a person or animals. It is widely used for automation in “smart home” systems such as turning on indoor lights or other mechanical devices. This is a highly sensitive PIR sensor with low power consumption. The quiescent current consumption is ≈50 µa. It is passive because the energy of infrared waves coming from the object itself is used to detect the object.

The sensor consists of a sensitive element and is triggered by infrared waves. Using a Fresnel lens, the infrared waves emitted by a living creature is focused on a pyroelectric sensor, which, when triggered, generates a pulse as a logical unit at the output. It has two modes of operation H and L. In H mode, each pulse is transmitted when triggered (multiple trigger mode). L mode allows you to receive a single signal with a subsequent delay.

In the ViaMyBox project can be used as part of the alarm system, when triggered, the video recording mode is activated. It can also be used when switching on various electromechanical devices through a controlled relay in a smart home system. To interact with the motion sensor with the Home Assistant remote smart home system, our project uses the mosquito (mqtt) protocol via wifi or ethernet cable. This protocol will allow connecting the sensor to any smart home system that has the ability to work with the mqtt protocol. It is sensitive to light and temperature changes, therefore it is recommended to avoid direct light rays during use.

Relay

In our ViaMyBox project, we use relays to control various electrical appliances in the Smart Home. The relays are controlled by the Raspberry Pi through the Home Assitant platform. But you can control the relay using any smart home platform that supports the mosquitto protocol (mqtt). The relay is controlled by the mqtt service. Home Assistant remotely interacts with this service via wifi or ethernet and allows you to control this relay through the web console of the Home Assistant Smart Home.
