Product Information

Easy to use sensors for exploring changes within your setting. Simply hold down the button and watch the LEDs change as you move around your school.

A beep is emitted to indicate higher or lower readings. How much do the sensors react when held towards a dark cupboard or a light window? Do more lights appear when the sensors are used in the classroom or in the playground?

Ideal for introducing the concept of ‘more than’ and ‘less than’ in early scientific enquiries. When the button is released, the sensor switches off, saving power.

  • Each sensor requires 2x AA batteries.
