38KHz Infrared IR Wireless Remote Control Receiver sensor Kit
Description:
This is their specific physical map
First, the introduction of This time we want to introduce an infrared transmitter and receiver modules, in fact, they are now in our daily life plays Important role in who is now on a lot of household appliances are used in such a device, such as air conditioning, TV, DVD, etc.,
It is based on wireless sensing, but also can be more remote control, very easy to use, then we today Day it is necessary to study the fundamentals and how to use. Second, Products
1. infrared emission control, also known as infrared emitting diode, it belongs to two Tube can be directly converted into electrical energy near-infrared lightAnd a light emitting device can radiate out, its structure, with the general principle of the light emitting diode similar, but with a semiconductor Different materials;
2. the infrared receiver is set to receive, amplify, demodulate one of the devices, which has been completed within the demodulation IC output Is a digital signal;
3, the principle of infrared communication.Let's look at the structure of the infrared receiver: infrared receiver inside there are two important elements, namely the IC andPD. IC is a receiver processing elements, mainly composed of silicon crystals and circuits, is a highly integrated device, the main To function as a filter, shaping, decoding, zoom and other functions. Photodiode PD is, the main function is to receive the optical signal Number.
The following is a brief schematic work The modulated infrared emitting diode signal emitted, infrared receiver after receiving, decoding, filtering, and a series of operations After the signal for recovery;
4 Notes
infrared emitting diodes: clean, good condition; various parameters during operation must not exceed limit values (positive To the current 30 ~ 60 mA, Pulse Forward Current 0.3 ~ 1 A, reverse voltage 5 V, power dissipation 90 mW, the working temperature Range -25 ~ +80 ℃, storage temperature range of -40 ~ +100 ℃, soldering temperature of 260℃) infrared emission tube and then Closed head should be paired with, otherwise it will affect the sensitivity;
