LIGHT SENSOR DEVICE


Summary

Students receive electronic parts, soldering tools. Their task is to plan and construct a light sensor that switches on during low light.

Educational subject: technology

Duration: one lesson (45 min)

Target group: gymnasium

Students age: 16-17 years

Context of professional activity: specialties related to electronics installation, maintenance equipment

Students are introduced to the task, giving them the details of the electronics, which they will need to properly thaw, so that the bulb will turn into darkness.

Task for students

Imagine being an electronics specialist. You need to install electronic part so that just after dark a light sensor mounted react and turn on the light bulb.

Measures

The measures are based on the students' ability to recognize the details of the electronics and how they are combined. For more advanced students, it is possible to give more electrician details so that students can independently decide what resources they need.

Parts and accessories required for the installation of a light sensor:

• soldering station

• Soldering with rosin

• mounting plate

• resistors

• current source

• connecting cables

• bulb

• item

• diodes

• converters

• photo resistor

• potentiometer

• capacitor

• thermistors


Lesson plan

5 min Students are introduced with the task, indicating the scheme under which the installation is carried out.

5 min Students are divided into groups receiving a task. They will be presented with the tools that they will benefit from, referring to safe working rules.

5 min Students are planning an experiment.

25 min Students carry out an experiment.

5 min An experiment is presented.

Homework

Find out where used pupils' home appliances.

Summary

Students use their knowledge of physics and technology to create a device that is useful in the home.
