4. using magnetron sputtering method at Porous Silicon area (21) the upper Au electrode (31) making two round point shapes, the diameter of described Au electrode (31) is 1mm, and thickness is 100nm.
Described data read module (33) is sent to the controller module being arranged within described detecting device by wireless communication module, described controller module is communicated with GPRS module by wireless communication module, and transmits the data value detected by described detecting device to detecting data basestation;
Further, described self energizing sensing element is additionally provided with a gas identification module (70), described gas identification module (70) is connected by wire and described data read module (33), described gas identification module (70) is mainly made up of shell body (71) and the gas detecting component (72) being detachably connected with shell body (71), and described gas detecting component (72) is controlled rete (73), instruction support powder (74) and glass tubing (75) and constitutes by diffusion; The preparation process of described gas detecting component (72) is as follows:
S1: the process of carrier and activation: the silica-gel carrier (90～100 order) sieved is placed in 600 DEG C of Muffle furnaces and calcines 2h, after cooling, bottle stand-by;
S2: the preparation of instruction carrier: the original liquid of measured amounts is put in a container, pours a certain amount of activated carrier into, stirring while adding, until mix homogeneously, till the supernatant is less. In atmosphere after natural drying, load in hermetic container stand-by;
S3: the preparation of glass tubing: select the glass tubing (specification is ID2.0mm × OD4.0mm) that internal diameter is uniform, transparency is good, intercept into the glass tubing some sections that length is 30mm, with sand paper by both sides hacking, then with suds, clear water, distilled water, glass tube cleaning is clean successively, dry stand-by;
S4: diffusion controls the preparation of film: adopt polyester film thick for 0.5mm to control film as diffusion, treats that polymer PET is dried, the circular membrane becoming external diameter to be 2.0mm with mould punching;
S5: the assembling of gas identification module: diffusion is controlled film binding agent and is adhered to the side of glass tubing, then weighs a certain amount of instruction support powder and slowly loads to glass tubing tight in glass tubing, and after smooth, the diffusion of bonding opposite side controls film.
