D100 Plug and Play Digital Gas Sensors

In order to solve the problems of limited replacement of core components, limited size, various types of gas detection and incompatibility of various brands of gas sensors, to cooperate with system integrators to develop industrial process control systems, environmental online monitoring systems and industrial internet gas analysis systems, and to solve the problem of integration of customers' independent systems, the D-100 plug-and-play digital gas sensor and the six-channel signal acquisitionintelligent motherboard M-600

•The D-100 digital gas sensor module is compact in size and simple to apply. The specific principle is: signal processing and intelligent calculation of different brands of sensors, then temperature and humidity compensation, and finally data calibration with standard gases.

•No secondary calibration is required, the standard RS485 or TTL digital signal of the sensor can be read directly, or a single or multiple 6-channel signal acquisition intelligent motherboard (M-600) can be selected for unified acquisition, hot-swappable support, the sensor can be replaced by itself after expiry, no professional operation or guidance is required.
