Ammonia sensor used in smart public toilet environment monitoring system
With the rise of the Internet empire, the integration and development of mobile technology, and the democratization of innovation, the construction of smart cities has become more rapid and perfect. Walking on the road of the city, you will see a smart public toilet every some distance. In my mind, the image of traditional public toilets is completely different. Smart public toilets are beautiful, comfortable, hygienic, clean, and intelligent. They not only improve the public image of the city, but also find a foothold in improving the level of modernization. This benefits from the application of the smart public toilet environment monitoring system. The smart public toilet environmental monitoring system consists of four parts: monitoring terminal, transmission part, management platform, and intelligent linkage, including temperature and humidity sensor, hydrogen sulfide sensor, ammonia sensor, ceiling infrared detector, environmental monitoring host, and network The relay and environmental monitoring cloud platform can monitor the temperature and humidity, hydrogen sulfide, ammonia and other environmental elements in public toilets in real time, and upload the data to the environmental monitoring platform in real time. When the harmful gas content in the public toilet exceeds the standard, the system can automatically link the fan to ventilate and deodorize, ensure the sanitation of the toilet and improve the environmental quality in the public toilet. In addition, some smart toilets also have a life monitoring function. When someone is found to be unwell and staying overtime, the system will send out an alarm message to pay attention to the safety of the toilet in time. In this system, the ammonia gas sensor is responsible for monitoring the ammonia gas. Ammonia is a colorless gas with a strong pungent odor. It is lighter than air. The relative molecular weight of ammonia is 17.031. It is easily soluble in water and alkaline. It is commonly used in laboratories. Ammonia gas is produced by heating two solid mixtures of ammonium chloride and slaked lime, and calcium chloride and water are also produced at the same time. It will decompose into nitrogen and hydrogen at high temperature, which has a reducing effect. It can be oxidized to nitric oxide in the presence of a catalyst. Ammonia can be produced by the direct synthesis of nitrogen and hydrogen under the action of a catalyst. It can burn the skin, eyes, and mucous membranes of respiratory organs. If people inhale too much, it can cause lung swelling. Due to the toxic nature of ammonia, it is necessary to monitor ammonia to ensure environmental safety. Ammonia gas sensor RS-NH3-*-2-* adopts imported first-line big brand acquisition chip, which has the characteristics of rapid response and strong anti-interference ability. After our unique compensation algorithm, multi-stage standard gas calibration, It also has the characteristics of long life, high precision, high repeatability and high stability. In addition to being used in public toilets, it can also be widely used in agricultural greenhouses, breeding farms, pesticide manufacturers, chemical plants and other occasions that require real-time monitoring and control of ammonia. The choice of ammonia gas sensor is different in different scenarios. If the sensor selection does not match the location of use, there will be many unexpected situations, so how should we choose? When selecting a sensor, you need to pay attention to the following points:1. Whether the selected ammonia sensor meets the range and resolution you need. 2. Whether the temperature, humidity, and air pressure in the ammonia gas detection environment are within the normal detection range of the sensor, otherwise, a pretreatment system needs to be installed at the front end for the ammonia gas sensor to be used normally. 2. Whether the ammonia concentration in the ammonia gas detection environment is below the detection normal range of the ammonia gas sensor, otherwise a higher range sensor is required. Smart public toilets combine the Internet, big data, cloud computing, Internet of Things, mobile Internet and other technologies to realize the refined management of urban public toilets. Among them, the smart public toilet environment monitoring system plays an important role. Through technical integration, the public toilet environment and equipment are effectively monitored and adjusted in real time, so that the public toilet is always in a clean, comfortable and hygienic state.
The use and installation of sensor solution is compared with most other systems for managing the OEM sensor effectively and no doubt sensor solution have won the race so many times.
Hunan Rika Electronic Tech Co.,Ltd take prudent risks and work together to assure our success and profitability in the future.
The best way of environmental monitoring systems is to get a OEM sensor sensor solution.
Hunan Rika Electronic Tech Co.,Ltd must adopts new technology and internal procedures to increase responsiveness and mitigate costs going forward.
We should take a step back to review how Rika Sensors approach tracking, implementing, and communicating compliance-related changes and attempt to identify areas of improvement in their processes.
