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;
Sepecification:
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 : -40 ~ +100 ℃,
soldering temperature : 260℃
infrared emission tube and then Closed head should be paired with,
otherwise it will affect the sensitivity
Competitive Advantage:
1. Convenient & Friendly Customer Service
2. Low Prices Direct From Factory Suppliers
3. Fast Delivery Around the World.
4. High Quality With Global Standards.
5. 1 Year Factory Warranty
6. Safe Shipping Way and Payment
