LDR Gasvalve Control

The customer’s challenge

Ko Hartog Elektrotechniek wanted a LDR gasvalve control board that is able to open/close a gas-valve by means of an electric motor and based on the light intensity. Such a product can be used to automatically turn gas-based lighting ‘on’ when it gets dark and ‘off’ again when it gets light.

ABA Electronics’ contribution

ABA Electronics designed, developed and produced the electronic hardware. Special care was taken in developing a device with low energy consumption and simple installation.


It is now possible to automatically switch a gaslight ‘on’/’off’ by means of the light intensity. The low power consumption increases battery life and the simple installation decreases installation time and prevents errors.
