AVT442 C

The set allows to make a system of remote switching on or off any load using a mobile phone. A relay fulfilling the role of an executive element can be switched on for a specified time or operate in a two-state mode. The system in no way interferes with the cell phone circuitry, the cooperation takes place using the optical connector. The light source is the phone's display - backlit when the device is in the state of receiving a call or text message. This condition detects the photoresistor of the attachment.

The device is particularly recommended as a simple remote control system using a GSM telephone

Selected parameters:

• adapter for a mobile phone
• control - optical (from the phone display backlight)
• delayed switching on of the actuator
• control of external circuits - relay
• programming of the switch-on time and operating mode (monostable / astable) - DIP Switch
• total galvanic separation from the telephone
• power supply - 12Vdc
