Ultra-Low-Power CO2 Sensors Enable Wireless Remote Monitoring for Building Management Solutions and IoT Connectivity
What is the problem that needs to be solved? Building Management Systems (BMS), Demand-Controlled Ventilation (DCV) systems and Indoor Air Quality (IAQ) equipment often require installation of wirelessly-connected, battery-powered CO2 sensor devices in environments where mains power is not easily accessible or where its provision is not economically viable; such…
Upgraded applications of High Sensitivity Piezo Film Sensor CM-01B in Conventional Medical Earphone
With no amplification function, conventional stethoscopes sound weak and make the ears uncomfortable. They cannot block ambient noise or adjust their frequency. Therefore, Isweek here puts forward a new type of high sensitivity contact microphone (piezoelectric sensor) used as a pickup part in electronic stethoscopes. It collects human life info with…
Security Control of New fuel cell vehicle hydrogen system Applying Sensing Technology
Applications of Combustible Gas Sensors in Intelligent Gas Leakage Monitor System
Applications of Temperature and Humidity Sensors in Smart Homes
In this era of IoT, people pursuing comfortable lives are paying more attention to health care and environmental quality. Smart city and smart homes appear consequently. Among all kinds of devices, environment monitoring devices used in smart homes are most popular, thus PM2.5 sensors and temperature and humidity sensors are…
Cost Effective PM2.5 Sensors, and Their Features
The working principle of PM2.5 sensors is based on light scattering. When being exposed to light, particles and molecules will absorb part of the energy, and scatter part of the light. When a light beam goes parallel into the particle field to be measured, the light is affected by scattering and…
A Compared Evaluation between Digital Output Temp&Humidity Sensor HTU21D and SHT21
Integrated temp&humidity sensors of small size and high accuracy are widely applied in cellphones, communication, HVAC, medical care, environment monitoring, home appliance and control panels. Here we ISWeek would like to make a comparison between the two best sellers in the market – HTU21D and SHT21- from aspects of their cost…
How to Select an Ideal Temp&RH Sensor for Cigar Cabinet`s Constant Temp&RH System
Cigar lovers are often concerning about the conditions of their cigar, since that good cigar can provide a joyful experience. The quality of cigars partially depend on its tobacco leaves, but mainly on its treatment. The newly bought cigars taste no better than immature fruits, so they need to be…
Applications of Combustible Gas and CO Sensors in Smart Homes
Nowadays, sensors have been integrated into everywhere of our life. They analyze users` daily behaviors and enrich users` interaction channels with their circumstances. Some smart sensors, like motion sensors and temperature & humidity sensors, enhance the safety and convenience of our life significantly. Sensors are essential in designs and solutions…
Solutions of Smart Monitor & Precaution System for Combustible Gases in Urban Sewage Conduit
Municipal sewers, sewage conduits, bilge wells and septic-tanks are containing and conveying sanitary and industrial sewage in urban areas. However, being sealed in such a relatively closed space, organic and inorganic matters in waste water can be resolved by microbial actions under anaerobic conditions to generate toxic and combustible gases….
Applications of Sensors in Monitor System of Utility Tunnels
With the acceleration of modern urbanization, the city pipe network is burdening increasingly heavier pressure to keep the city’s smooth operation. The expansion, transformation and maintenance of the pipelines always bring people lots of inconvenience, and cause large economic waste. Every year loss of hundred billions yuan is directly or…
