VS1838

The VS1838 Infrared Receiver operates at the frequency of 38KHz, which is the frequency of most remote controls. For its operation, a micro-controlled platform is required.

In home automation projects with Arduino, PIC, or NodeMCU ESP8266 the IR Fotoreceptor / Receiver is TSOP4838 widely used. Together with an IR Emitter LED and the microcontroller platform, it is possible to replace the remote control of the devices (TV, DVD, BluRay, stereo) and use an alternative control system through a smartphone or tablet with an Android app for example.

Specifications:
• Working voltage: 2.7V~5.5V;
• Current consumption: 1.5uA;
• Working frequency: 38Khz;
• Angle: +/- 45°;
• Low logic level voltage: 0.4V;
• High logic level voltage: up to 4.5V;
• Working temperature: -20° ~ 85°.
