HA-THVOC Five in One Air Quality Sensor: Ceiling mounted, real-time monitoring of TVOC/smoke/CO ₂/temperature and humidity, linked with fresh air system to protect respiratory health

Indoor air cannot be seen or touched, but are you really confident in letting children and elderly people breathe every day? Have you ever had the experience of feeling a strange odor after renovating a new house, but not knowing if it's formaldehyde or excessive TVOC? The kitchen is filled with cooking fumes, but the smoke alarm is unresponsive. Can you only rely on your intuition to open the window for ventilation? In winter, the air-conditioned room feels stuffy and dizzy, and the concentration of carbon dioxide has already exceeded the standard, but you are completely unaware? What's even more frustrating is that many household air quality detectors on the market have low accuracy, slow response, and data that can only be viewed but not used - a string of numbers displayed on a mobile app but cannot be linked to any device. When you really want to use this data to control the fresh air fan, purifier, and exhaust fan, you realize that they simply cannot connect to the Home Assistant. If there is an industrial grade precision air quality sensor that can simultaneously detect TVOC, smoke, CO ₂, temperature and humidity, and can be installed on the ceiling without taking up space, it can also be natively connected to HA to achieve intelligent linkage - would you immediately install one at home?

Five sensors on top of each other. The traditional approach requires monitoring these five indicators by installing at least 2-3 different sensors - a TVOC/CO ₂ detector, a smoke alarm, and a temperature and humidity meter. Not only is the procurement cost high, but the installation location is also difficult to coordinate. The five in one design of HA-THVOCsignificantly reduces system deployment costs and space occupancy. Moreover, the MEMS process brings characteristics such as fast response, fast zeroing, and good resistance to poisoning, ensuring the stability and reliability of long-term online monitoring.Fast response, fast return to zero, and good resistance to poisoningThe characteristics ensure the stability and reliability of long-term online monitoring.

Applicable audience and scenario

The most suitable for these three types of people

• Home Assistant PlayerI want to integrate indoor air quality data into HA to achieve intelligent scenarios such as fresh air linkage and over limit alarm;

• New house decoration/families with children: Pay attention to decoration pollution such as formaldehyde and TVOC, and hope to monitor and link purification equipment in real time;

• System integrator/contractor: We need to select a cost-effective air quality sensor for building automation and smart home projects.

Three typical landing scenarios

• Whole house air quality management: Install HA-THVOC on the ceiling of the living room to monitor TVOC, CO ₂, temperature and humidity in real time. When TVOC exceeds the standard, the fresh air fan will be automatically turned on. When CO ₂ is too high, the exhaust fan will be automatically turned on. When the temperature and humidity are abnormal, the air conditioner and humidifier will be linked.Automatically maintains optimal indoor air quality 24/7 without the need for manual intervention.

• Kitchen Smoke Monitoring Linkage: Install HA-THVOC in the kitchen to automatically turn on the range hood and exhaust fan when the smoke concentration exceeds the standard, while pushing mobile phone alarm notifications.You no longer have to worry about the spread of oil fumes and safety hazards caused by forgetting to turn off the fire.

• Monitoring of Sleep Environment in Children's Room/Bedroom: Installed on the ceiling of the children's room, real-time monitoring of CO ₂ concentration and temperature and humidity at night. When CO ₂ is too high, the micro ventilation mode is automatically turned on, and when the temperature is too high, the air conditioning is automatically turned down, creating a comfortable sleeping environment for children all night long.Create a comfortable sleeping environment for children throughout the night.

User Witness and Summary

"My home has just been renovated, and my biggest concern is formaldehyde and TVOC. I have bought a portable detector for a few hundred yuan before, but the data is fluctuating and I don't know if it is accurate. After replacing the HA-THVOC, the data of theindustrial grade MEMS sensor became significantly more stable. As soon as the TVOC exceeded the standard, the fresh air automatically turned on, eliminating the need for constant suspicion. After connecting to HA, you can still see the historical trend chart. After three months of decoration, TVOC decreased from 180 μ g/m ³ to 15 μ g/m ³. Watching the data gradually improve, I feel much more at ease. ”Ms. Liu, a Beijing homeownerAfter three months of renovation, the TVOC decreased from 180 μ g/m ³ to 15 μ g/m ³Watching the data gradually improve, I feel much more at ease. ”Ms. Liu, a Beijing homeowner

, said, "As someone who specializes in building intelligence projects, we used to provide air quality monitoring solutions for our clients. We had to purchase TVOC detectors, smoke alarms, and temperature and humidity meters, which were difficult to install and debug, and had high costs. After using HA-THVOC,one sensor can handle five parameters, and the installation of the Φ 90 ceiling is particularly convenient. Modbus is directly connected to our BA system. A project saved at least 30% of sensor procurement costs, andinstallation hours were also reduced by half. ”A smart building integrator in Shanghai, Mr. Wang
