PIR (infrared and dusk-to-dawn) motion sensors allow automatic activation of the light sources connected to them.
The PIR electronic circuits and dusk-to-dawn switches by Erresei are all Made in Italy, manufactured in-house and designed to minimize the overall dimensions.
Our products are of top quality and reliability and are studied to manage low voltage lighting solutions.
Some models offer the possibility of adjusting both sensibility and activation time at the discretion of the end user.
