Lesson 3

Case for sensors
In order to make a case for a gas leak detector, you can choose one of the following methods:

– 3D printer (an instruction is given on creating a 3d-model of the hull

– BEN-maker – a machine for working with wood (before starting work, explain to the students the basic safety rules for working with the machine)

– any cardboard or plastic box (recommended)

Photo instruction case modelling

– calculate the dimensions of the display and each sensor separately

– draw an exact drawing in the SketchUp program

– we send for printing after selecting the material of manufacture

– install sensors inside the case

– it is necessary to take into account that the sensors are heated, and for ventilation and air circulation, several small holes must be cut on the back of the case.

 Assignment for the next lesson:

 -Prepare a video and upload it to the TikTok platform

The length of the video should be in the range of 1-3 minutes and should be in three parts

-First part: problem (in our case, problems with gas leakage)

-Second part: solving this problem

-Third part: demonstrate your project
