Wi-Fi radar presence sensor PNI SafeHouse HS402

Product detailed description

PNI SafeHouse HS402 is a Wi-Fi presence sensor that uses millimeter-wave radar instead of a conventional motion sensor. This allows it to detect not only movement but also static presence, meaning a person who is not moving within the range. The detection radius reaches up to 10 meters, and the device complements this with distance and brightness measurements. Through the Tuya app, you gain an overview and control of your home environment.

Main Features

• radar-based detection of movement and static presence
• range of 0 – 1000 cm (10 m) with a detection angle of 120°
• distance and brightness measurement in the range of 0 – 2500 lux
• instant alarm on movement and a separate alarm for static presence
• adjustable sensitivity
• compatibility with the Tuya app
• power supply 5 V DC / 1 A via USB-C port
• quick mounting using the included adhesive tape

Frequencies and Connectivity

The sensor connects to your home network via Wi-Fi at 2.4 GHz. The radar part operates at a radio frequency of 5.8 GHz, which, according to the manufacturer, improves communication and reduces interference. The detection angle of 120° ensures wide coverage of the area, and the light sensor detects brightness from 0 to 2500 lux.

Usage

The sensor is suitable for offices, where it detects the presence of employees, as well as for homes, where it enhances security. It can be used to monitor hallways, living rooms, or courtyards and will alert the user in case of unusual movement. Data on distance and brightness can also be used to automatically adjust interior lighting according to ambient conditions.

Power Supply and Installation

The device is powered via USB-C. The package includes a power adapter 230 V – 5 V / 1 A, a USB-C cable, and double-sided adhesive tape to attach the sensor to any surface. The compact modern design allows it to be placed discreetly without complicated installation.
