Semiconductor sensor for VOCs detection

The utility model discloses a semiconductor sensor for detecting VOCs (volatile organic compounds), which comprises a basic framework, the basic framework is formed by taking a wrapping pipe, a wrapping material and a wrapping head as an external main body and taking a device core and an electric heating piece as an internal main body, and relates to the technical field of VOCs detection. According to the invention, through building the framework with the base frame as the basis, in the connection process of the VOCs semiconductor sensor and the PCB, a stable installation mode or a convenient installation mode can be selected, and the connection mode of the VOCs semiconductor sensor is convenient; meanwhile, the electric wire cable pulled out of the electric wire contact is clamped, limited and fixed through a wing plate in the base frame, the problem that the electric wire cable falls off from the electric wire contact due to shaking of the electric wire cable can be prevented, the damage probability of the
