Clean air is essential for our health and well-being, but with rising pollution, it’s becoming harder to know if the air we breathe is safe. This is where air quality sensors like the FS00802G come in, acting like tiny sentinels that measure key pollutants in the air around us.
Think of these sensors as your air detectives, sniffing out things like dust particles (PM2.5), carbon dioxide (CO2), and even harmful chemicals like formaldehyde (HCHO). They do this using clever technology, and while the details might be complex, the result is simple: a number representing the level of each pollutant.
But how do we access this information, you ask?
Well, that’s where IoT gateways like the HashStudioz RS-485 gateway come in.
Instead of manually taking air samples and sending them to a lab (which can be expensive and time-consuming), these sensors and gateways give you real-time information right on your screen.

Understand HashStudioz RS 485 IoT Gateway
An RS-485 IoT Gateway is a device that allows you to connect multiple devices and to the internet. This is useful for devices that are far away from each other and cannot be directly connected. The RS-485 IoT Gateway supports Modbus RTU to Modbus TCP, which means that it can convert data from one format to another. This makes it possible to connect devices that use different communication protocols.
The RS-485 IoT Gateway has several features that make it useful for industrial applications, such as:
- It can be used to collect data from sensors and other devices.
- Ethernet interface
- Wi-Fi Antenna
- Operating temperature between -40℃ to 85℃
- The gateway operates on a voltage range of 6-30v.
- The gateway uses a microSIM card with 4G data capability.
- It attaches IEEE 802.11b/g/n network devices with serial and Ethernet ports.
- It handles Virtual COM, TCP server/client, UDP server/client, and HTTPS client.
- It provides Modbus RTU to Modbus TCP support.
- With just one RJ45 Ethernet interface, it offers numerous networking modes.
- Specific MQTT/SSL firmware
System architecture
The system consists of the following three main parts:
- FS00802G air quality sensor positioned in an outdoor environment for measuring the different air quality indicators such as PM2.5, PM10, CO2
- The HashStudioz RS-485 IoT gateway transmits data securely over Wi-Fi with low power consumption to cloud
- A cloud server
- A web-based user application(IoT Dashboard) to display real-time, historical data, and interactive charts.
How RS485 IoT Gateways Read Data from FS00802G Sensor and visualize on the IoT dashboard
Our IoT gateway serves as the cornerstone of our air quality monitoring solution, providing a robust platform for data aggregation, analysis, and visualization. Designed with versatility and scalability, our gateway facilitates seamless integration with a wide range of sensors, including the FS00802G air quality sensor.
Our IoT gateway employs advanced data analytics algorithms to parse, analyze, and visualize air quality data collected from the FS00802G sensor. Through intuitive dashboards and graphical representations, users can gain valuable insights into air quality trends, fluctuations, and potential environmental risks.
Step 1: Data Acquisition from FS00802G Sensor
The journey begins with the FS00802G sensor diligently collecting air quality data. Equipped with advanced sensing technologies, it measures various parameters such as particulate matter (PM2.5 and PM10), carbon dioxide (CO2), temperature, and humidity. The sensor communicates this data to the RS485 IoT gateway using the RS485/Modbus communication protocol, ensuring reliable and robust data transmission.
Step 2: RS485 Gateway Data Reception
Upon receiving data from the FS00802G sensor, the RS485 IoT gateway springs into action. It acts as a vigilant receiver, capturing the incoming data packets and preparing them for processing. It establishes connections with sensors using Modbus RTU for serial communication. It retrieves various data types like pm2.5, pm10, pm1.0, TVOC, temperature, humidity, ozone, alcohol, methane, ammonia, hydrogen sulfide, sulfur dioxide, and other air quality indicators based on configured registers.
Step 3: Data Processing and Conversion
The RS485 IoT gateway serves as the brain of the operation, processing, and converting raw data into a standardized format. This involves parsing the data, validating its integrity, and converting it into a format suitable for transmission.
Step 4: Transmission to Cloud Server Platform
With the data processed and formatted, the RS485 IoT gateway equipped with the Modbus protocol, embarks on its next mission, As the IoT gateway acts as a central hub, it continuously ingests streams of data payloads from the sensor. These raw payloads, containing valuable sensor readings, are then processed and transformed into a standardized format. Subsequently, the gateway uploads this streamlined data to the cloud server, ensuring its swift and reliable delivery.
Step 5: Visualization and Actionable Insights
Finally, you can access air quality data arriving at its destination: the dashboard from the cloud server. Here, it comes to life through intuitive visualizations and interactive charts. Users can monitor real-time air quality parameters, track historical trends, and set up alerts for anomalous readings. With actionable insights, stakeholders can make informed decisions to improve environmental conditions and enhance public health.
