The "315 Mhz RF Module" is a set of two wireless communication modules commonly used in electronics and DIY projects. 315mhz RF Transmitter and Receiver modules facilitate the wireless transmission and reception of data or signals over a distance using radio frequency (RF) technology.

Here's an explanation of each part:

RF Transmitter Module:

The RF transmitter module is a small electronic device capable of transmitting data or signals wirelessly using radio waves. It operates at a specific frequency, in this case, 315MHz. These modules typically have a few input pins for data or signals that need to be transmitted. When data is applied to these input pins, the module encodes it into radio waves and broadcasts it through an antenna.

RF Receiver Module:

The RF receiver module is a counterpart to the transmitter module. It is designed to receive the transmitted radio waves and decode the data or signals back into their original form. Like the transmitter, the receiver also operates at 315MHz and has output pins that provide the received data or signals.

Wireless Communication:

When the transmitter module sends data, the receiver module captures it, allowing for wireless communication between two devices. This can be utilized in various applications, such as remote control systems, wireless data transmission, communication between microcontrollers or embedded systems, and more.

Frequency of 315mhz RF Transmitter and Receiver:

The "315MHz" frequency indicates the radio frequency at which these modules operate. This frequency is within the range of the ISM (Industrial, Scientific, and Medical) bands, which are reserved for unlicensed use in many countries.

Both the transmitter and receiver modules are relatively easy to use and integrate into projects, making them popular components for creating wireless communication links between devices. However, it's essential to understand the local regulations regarding the use of radio frequencies to ensure compliance and avoid interference with other communication systems.

Great product, just one "issue".

So far so good! They communicate pretty effectively at a decent distance. Only issue I had was with getting the right frequency for the receiver. It wasn't calibrated at the factory. To those that are struggling: hook the pair up to some Arduinos and have one constantly transmit a signal, on the receiving end, just continually scan for that signal and slowly turn the frequency knob until you pick it up. Best wishes! Stay creative.

... dozens of these over the years and they work great!

I have purchased dozens of these over the years and they work great!

Fun projects

Transmitter and Receiver works like a charm

Transmitter and Receiver works like a charm.Only request from the manufacturer is to label the frequency on the Receiver piece.

Does what it does

It takes the air and makes it 315mhz bits instead. It did this with modest efficacy.Clearly recycled parts which is good.Probably made with slave labor. :-(
