Air Quality within a home or commercial building can be far worse than that outdoors as there might be higher concentrations of Volatile Organic Chemicals (VOCs), carbon dioxide (CO2) and monoxide (CO) and particles. Monitoring those parameters as well as relative humidity and temperature, can provide alerts to occupants and turn on systems that could improve air quality including air purifiers, ionization conditioning and dehumidifiers.

We have a wide offer of ultra-low power STM32L 32 bits microcontrollers and ultra-low power wireless connectivity solutions – including Bluetooth low energy and sub-GHz - as well as cloud connectivity sw packages, temperature, humidity and proximity sensors and high precision operational amplifier for chemical sensors signal conditioning.

In addition we provide a comprehensive set of HW and SW evaluation and development tools to help design ultra-low power.
