TANGER SWITCH - THE SYSTEM HOLDED AND LAUNCHED

Producer: AVT

A typical application of the proposed system is lighting the garden or yard of farm buildings. The twilight switch function is based on the popular TL081 system (operational amplifier). It compares the voltage from a divider built using a photoreistor with a reference voltage. Changing the intensity of illumination (and in particular lowering it) turns on the output relay and powering the lighthouse connected with it.

The device is especially recommended where it is necessary to use the night lighting of the area

Selected parameters:

• light sensor - photoresistor
• smooth regulation of the threshold (sensitivity)
• hysteresis of operation that eliminates oscillations when the lighting is on the limit of operation
• work signaling - LED diode
• executive element - relay
• contact load 8A / 230Vac
• power supply - 12-15 Vdc
• dimensions of the plate 32x54mm
• system assembled and running
