Product details Circuit is selected for highest differences of voltage proportional to light in dusk and dawn period (low light). Connecting diagram is descripted in LAN Controler manual. After connecting desired voltage - about 1V (as dusk light edge) should be set up in Even Config to switch output in purpose switching on night lighting. Sensor should be mounted in place where will be not lighted by artificial light, specially by cars lamps. TECHNICAL SPECIFICATIONS: Resultant voltage in complete dark ca 3,1V Resultant voltage during cloudy day ca 0,2V Resultant voltage during dusk or dawn 0,8-2V
