Abstract: A handheld gas sensing device and sensing method thereof are provided. The handheld gas sensing device includes a plurality of gas sensing chips and a gas collector. The plurality of gas sensing chips respectively include a sensing array, a sensing interface circuit, a microcontroller, and a memory. The gas signal is determined by the gas adsorption of the sensing array. The gas signal is converted to a visible operand by using the sensing interface circuit. The visible operand is projected to a hidden operand by utilizing the calculation of Continuous Restricted Boltzmnan Machine (CRBM). The plurality of gas sensing chips are connected with each other to do the multi-layer calculation of CRBM. The probability of the to-be-detected gas is obtained. The result is recorded in the memory.
