Infrared remote control and Bluetooth remote control are better than Bluetooth remote control or infrared remote control

Basic principle of infrared remote control

The infrared remote control transmitter circuit (remote control) is composed of infrared emission diode, triode or photosensitive triode, air conditioner, fan, etc.) is composed of infrared emission diode, triode or photosensitive triode. They will convert the infrared light of the infrared transmitter into the corresponding electronic signal, and then send it to the rear amplifier, and send it to the channel. The demodulation circuit will recover the modulated control instruction encoded signal to the encoded signal, and then decode the data encoded control instruction signal through the control instruction compiler. Finally, the driver will implement the circuit to complete various control instruction operations.

Basic principle of Bluetooth remote control

Bluetooth remote controller corresponds to low-power Bluetooth ble to complete wireless transmission and remote operation of machine equipment

Main differences between the two

1. Whether to pair

Infrared remote control: not required

Bluetooth remote control: required

2. Use distance

Infrared remote control: 3-5m

Bluetooth remote control: about 10m

3. Penetration

Infrared remote control: cannot pass through obstacles, and must be aligned to transmit signals

Bluetooth remote control: strong penetration ability, can be controlled through the wall, strong signal, 360 ° omni-directional without dead angle

4. Immunity

Infrared remote control: weak. The sensor of the infrared remote control is blocked and completely out of control

Bluetooth remote control: one-to-one control after pairing, strong anti-interference

5. Power consumption

Infrared remote controller: with high power consumption led, high power consumption

Bluetooth remote control: low power consumption of Bluetooth remote control similar to infrared remote control is only 10%

6. Safety

Infrared remote control: unable to encrypt

Bluetooth remote control: encryption

7. Functions

Infrared remote control: single function

Bluetooth remote control: rich, voice module can be added to complete the intelligent control system

8. Price

Infrared remote control: low

Bluetooth remote control: high
