ZI01 is a high-performance PID sensor module, which adopts PID sensor and high-performance microprocessor. The target gas is bombarded with ultraviolet light generated by an ion lamp. Then gas is illuminated by the ultraviolet light produced by ion lamp, which will be ionized after absorbing enough ultraviolet light energy. Concentration of the target gas can be detected by measuring the tiny current generated by gas ionization.
The module can accurately measure the concentration of a variety of volatile organic compounds (VOCs) in the environment. It has digital output and analog voltage output, which is convenient for users to use and debug, and greatly reduces the design and development cycle for users. It perfectly combines PID sensor and circuit to meet the needs of customers for field detection.

Application

It is widely applicable to portable and fixed gas detectors, as well as various occasions and equipment requiring VOC gas detection.

The range of the module and the voltage of VO are not completely one-to-one corresponding. The voltage in the above table is the normal detection range. If the voltage exceeds this range, it may be abnormal for the module. The specific corresponding voltage value of VO shall be subject to the test report or the measured data in the Excel sheet provided.
