How to choose the remote control for for your device?

1. Wireless remote control,
2. Woring freqency:（315MHz/433MHz，other）and the IC for the transmitter
3. Feature：the transmitter distance
4. From 50m to 1000m :
5. Metal remote control: About 100m
6. Small plastic remote control : about 150m-200m
7. High power remote control with plastic cover :1500m
8. Battery:27A/23ABattery,Current:8mA

IC Model:

1. Fixed code:it's named codes remote control or Welding codes remote control，the transmitter ic :PT，SC，HS，LX (2260/2262/2264），The paired receive chip: PT，SC，LX，HS(2270/2272/2294）.you need distinguish the oscillation resistance of the transmitter and receiver for the fixed code.
2. Learning code:EV，HS，LX。SC (1527/2240)，HCS101 etc.PIC16F630，PIC16F505，PIC16F629 etc.
3. Rolling code:HCS301/200/201 etc.

In a word:

1. Same working frequency,Same IC,Same oscillation resistance,
2. fixed code to match fixed code,Learning code lto match Learning code,Rolling code to match Rolling code.
3. the Pin Assignment
