Application of Longshow 1cm single point pressure sensor in smart LED

steering standard jacket
The scheme introduces making a simple turning mark of the jacket,

wearing the can by pressing sleeve bending sensor to open or close the

turning signal. This scheme requires only two 1cm in diameter, the

Longshow thin film pressure sensor (measuring range and 1kg, as shown

in Figure 1), 4 of a red LED, 3 meters long conductive sewing line, a

lilypad (it is a piece of the wearable devices and electronic placed

product design of the micro controller board, as shown in Figure 2).

It is more convenient to use a curved sensor while riding a bicycle. A

1cm in diameter, Longshow dynamic film pressure sensor, by slightly

bending operation, quick change of internal resistance, it can users

easily switch signal, the scheme applicable in children's clothing,

car and other clothing.

Bending sensor is not easy sewing in a cloth, it is recommended that

in bending sensor paper cover with a piece of cloth, and then the

sewing to the inner layer of the jacket cuffs. The cloth covered on

the sensor does not affect its operation or readings at all, so it is

very reliable.

 

The application code is very simple, you can read out the numerical

simulation from bending sensor, if the change in the value exceeds a

predetermined value, LED will light 10s. "Change the value quantity"

means when gentle pressure on the sensor does not trigger it, which

for cyclists is very convenient, because the user may sweeps or hold

something.

 

For the improvement of the jacket, to add a speaker or click on the

vibration can be, so that you can with voice or vibration to prompt

the user to signal has been opened.
