Embodiment
A kind of ambient temperature and humidity meter with touch key-press that the present embodiment proposes, as depicted in figs. 1 and 2, including a LCD
Display screen 1, the backlight 2 of light source is provided for LCD display 1, the master control pcb board 3 being electrically connected with LCD display 1, with master control
The temperature sensor 6 and a humidity sensor 7 that pcb board 3 is electrically connected with, a power supply 14.If LCD display 1 is provided with
The input of dry touch key-press, each touch key-press and a button pcb board 4 is electrically connected with, the output end of button pcb board 4 and master control
Pcb board 3 is electrically connected with.
It should be noted that master control pcb board 3 is provided with the main control chip of a model SG8L129 of the prior art, use
Sent in the data processing to Temperature Humidity Sensor and order.Button pcb board 4 be provided with one in the prior art touch-screen it is conventional
IC chip is touched, for handling the command signal of touch-screen.
Further, LCD display 1 is formed by the fitting of two ITO electro-conductive glass, and touch key-press is arranged to be mounted side by side on two
Sensing metallic film 5 in ITO electro-conductive glass interlayers.Preferably, the quantity for sensing metallic film 5 is arranged to three, three senses
Answer metallic film 5 to be connected in three PINs of LCD display 1, then conductive adhesive tape 8 and button pcb board are led entirely by one
4 touch IC three input haptic elements are electrically connected with, and touch the output end that IC is provided with corresponding main control chip.When people is touched with finger
Corresponding to touching during touch key-press, sensing metallic film 5 senses touch operation, and a corresponding low level is sent by touching IC
