The kit is consisted of transmitter and receiver, popular used for remote control.
Specification:
- Frequency: 433Mhz
- Modulation: ASK
- Receiver data output: High - 1/2 Vcc, Low - 0.7v
- Transmitor input voltage: 3-12V (high voltage = more transmitting power)
- Transmitting range (work at 5V): 40m indoor, and 100m in open air
Usage:
The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU
PT2272(Encoder) and PT2262(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection.
Excuse for the documentation, we will work on them. Before that, please consult us for any details, we are happy to find the answer for you. We tried them using the guide from Sparkfun, it's compatible. The only difference is in package, of some excess GND pins.
Moreover, we will make more RF modules ourselves with different frequency and capacity. The next one in plan is based on cc1100 Please suggest us about your need .
