A. Product Overview

The Temtop S1 Plus Bluetooth Indoor Air Quality Meter is a compact and portable air quality monitoring device used for real-time indoor environment checking. It helps users monitor important air quality parameters such as PM2.5, AQI, temperature and humidity from one device.
The meter comes with a clear digital display that shows PM2.5 value, AQI level, temperature, humidity, battery level, time, working mode, and air quality indicator bar. It also supports Bluetooth connectivity, allowing users to connect the device with a mobile app for better data monitoring, historical trend viewing, data export, device calibration and custom settings.
Its portable design makes it easy to place on a desk, attach magnetically or use with a bracket. The device is designed for simple daily use in indoor spaces where air quality, dust level, comfort and pollution monitoring are important.

B. Working Principle

Temtop S1 Plus works by continuously drawing indoor air through its internal air sampling system. The built-in sensor detects fine particulate matter in the air and measures PM2.5 concentration. Based on the PM2.5 reading, the device calculates and displays the AQI level so the user can understand whether the air quality is good, fair or poor.
At the same time, the temperature and humidity sensor measures the indoor environmental condition. These readings are shown directly on the display along with an air quality color indicator. The Bluetooth function allows the measured data to be sent to the mobile app, where users can check trends, export data, adjust settings and manage device functions.
When the air quality crosses a set level, the visual and audio alert system helps users identify poor air conditions quickly.

C. Why It Is Used

Temtop S1 Plus is used to monitor indoor air quality and help users understand the condition of the air they breathe. Outdoor AQI data does not always show the actual air quality inside a room, office, classroom or closed indoor space. Indoor pollution can change due to dust, ventilation, cooking, cleaning chemicals, smoke, closed windows, nearby traffic pollution, pets and HVAC performance.
This device helps users:

• Monitor PM2.5 and AQI in real time

• Check temperature and humidity for indoor comfort

• Identify poor indoor air quality early

• Take action such as ventilation, air purifier use or HVAC adjustment

• Track air quality changes through app-linked data

• Receive visual and audio alerts during poor air conditions

• Maintain a healthier indoor environment

It is useful for people who want a simple, portable and connected air quality monitor for regular indoor use.
