315MHz Wireless Transmitter Module and Receiver Module (One way Communication)
This unit contains a single IC chip with three pins as the transmitter and a single four pin IC for receiver. Plug one end to a microcontroller and the other to another, send long distance code or commands. This unit can send information through walls with a range of less than 200m. You are required to use a small 22 – 24 AWG cable and insert the stripped cable into ant through-hole.
