NH3 gas sensor in smart public toilet


Smart public toilets are beautiful, comfortable, hygienic, clean and intelligent. This is due to the application of NH3 gas sensor monitoring system in intelligent public toilets.

It not only improves the public image of the city, but also finds a foothold for the promotion of modernization.

Introduction to Smart Toilets:

The intelligent public toilet environmental monitoring system consists of four parts: management platform, monitoring terminal, intelligent linkage and transmission.

All kinds of gas detectors, including NH3 gas sensor, can monitor the concentration of ambient gases such as temperature, humidity and ammonia in public toilets in real time, and upload it to the environmental monitoring platform in real time.

When the harmful gas content in the public toilet exceeds the standard, the system will send an alarm message to timely pay attention to the safety of the toilet users.

In this system, the NH3 gas sensor is responsible for monitoring ammonia gas.

Ammonia introduction:

Ammonia is a pungent, colorless gas, lighter than air.

Ammonia is alkaline and soluble in water. In the laboratory, ammonia gas is made by heating a mixture of ammonium chloride and hydrated lime, which also produces calcium chloride and water.

At high temperature, it will decompose into nitrogen and hydrogen, with reducing effect. It can be oxidized to nitric oxide in the presence of a catalyst.

Ammonia can be directly synthesized from nitrogen and hydrogen with a catalyst and can burn the mucous membranes of the skin, eyes and respiratory organs, causing the lungs to swell if inhaled in excess.

As ammonia is a toxic gas, it is necessary to monitor ammonia to ensure environmental safety.

Sensor introduction:

Electrochemical ammonia sensor uses semiconductor sensor probe as the core detection device.

It has the characteristics of fast response, high sensitivity and strong anti-interference ability. It also has the characteristics of long service life, high accuracy and stability.

In addition to being used in public toilets, it can also be widely used in agricultural greenhouses, breeding farms, chemical plants and other occasions where ammonia gas needs to be monitored.

Ammonia electrochemical sensor plays an important role in intelligent public toilet environmental monitoring system.

Through technology integration, the environment of public toilets can be monitored in real time and effectively, so that public toilets are always in a safe and clean state.
