The DS4 intelligent formaldehyde sensor from EC Sense in Germany adopts reliable printed solid - state polymer electrochemical sensor technology and is an industrial - grade intelligent gas sensor. With its small - volume and compact structural design, it is equipped with a high - performance microprocessor, a high - precision analog - to - digital converter, and an intelligent algorithm design. It can be easily integrated into the Internet of Things and other monitoring systems, and is widely used in industrial, commercial, civil, and medical fields.

Product Features

• Stansnoisnedard Industrial Dimensions
  Designed with the standard industrial 4 - series dimensions, it has a cylindrical housing of 20 x 16.6mm. Users can easily carry out iterative design of new products. It is suitable for fixed - type gas detectors and portable detection instruments, saving the housing design cost brought by new product upgrades. It has standard three - electrode pin sizes (VCC - positive power supply, GND - negative power supply, IO - data transceiver).
