產(chǎn)品簡介

7R+PIDsensorisaselfcontainedintelligentsensormodulewithbuilt-insensorprocessor,lampdriver,analoganddigitalinterfacecircuits

詳細介紹

7R+ PID sensor is a self contained intelligent sensor module with built-in sensor processor, lamp driver, analog and digital interface circuits. It is designed to detect volatile organic compound (VOC) with a standard external interface. It allows the sensor module to be easily integrated into a wired or wireless communication system for remote, wide area and pervasive monitoring applications. The sensor module can be powered by typical 5VDC. It is housed in a stainless steel enclosure with a standard 8 pins interface connector.
