Zest_Sensor_VOC

Overview

The Zest_Sensor_VOC is an electronics development board for 6TRON open source platform built around the CB-HCHO-V4 HCHO(Formaldehyde) gas sensor from Cubic.

The CB-HCHO-V4 integrates the following parameters:

  • Dectection principle : electrochemical

  • HCHO detection range :0 tp 1ppm,

  • VOC detection range :0 to 10ppm

  • TVOC detection range :0 to 10ppm.

The Zest_Sensor_VOC offers 6TRON users a Formaldehyde gas sensor to monitor air quality in health, environmental and industrial applications.
