Optical Sensors - Photo Detectors - Remote Receiver

TSOP77236TR is a kind of photo detector device especially designed for receiving infra-red signals. It has advantages such as low-cost and wide application field. This nano incident IR receiver module is especially suitable for applications in medium to short-distance communication.

Application Field

TSOP77236TR is widely used in plenty of fields, such as home appliance remote control, fire alarm, medical development environment, remote control running through IR data packet, controlled robots, controller development, wireless doorbells, home lighting control, and so on. It is a perfect choice for products that require either physical buttons or long-distance communication.

Working Principle

TSOP77236TR mainly includes two parts, an integrated IR receiver and an IC decoding signal. IR receiver can receive transmission signals sent by infrared signals. The received signals will be firstly filtered by a bandpass filter. After that, a band-reject filter will filter out noise. Then the modulated signals will be input into AGC amplifier. After the amplification, the output sign will be processed by a demodulator, then the signal will be sent to the IC decoder. Finally the signal is converted to digital output.

Receiving Distance

Receiving distance is related to ambient temperature and some environmental factors. Generally speaking, under normal temperature, the receiving distance could reach up to 10 meters. In addition, the receiving angle is up to 20 degree.

Key Features

• Wide receiving angle: up to 20 degree
• Wide supply voltage range: 2.4V ~5.5V
• High receiving sensitivity: up to -100dBm
• Low power consumption
• Strong anti-interference
• High response speed: up to 5kbps
• Small size and light weight

Conclusion

TSOP77236TR is a cost-effective solution for short-distance infrared communication. It features a wide receiving angle, low power consumption, strong anti-interference, and high response speed. The receiving distance can reach up to 10 meters under usual temperature. Therefore, this device can be used in plenty of fields, such as home appliance, medical, robot control, remote control and so on.
