433MHz

> A Node package to transmit data on a Raspberry Pi using a 433MHz sender.

Note: I made this for my cheap remote outlets, I don't know if this is actually useful with other devices lol.

Be aware of command injection: the binary code you pass to transmitCode is passed directly into exec (no sanitization)!

Installation

``sh
npm install 433MHz
`

Usage

`js
const { transmitCode } = require('433MHz');

// Input the code that you want to be transmitted
transmitCode('1111111111111111111010111');

// You have multiple options to customize the transmission
transmitCode('1111111111111111111010111', {
transmitPin: 18,
shortDelay: 0.001,
longDelay: 0.005,
packetDelay: 0.05,
});
`

$3

#### transmitPin
This is the pin, the data pin of the transmitter is connected to on the GPIO.
Default: 18

#### shortDelay
The short delay between pin output state changes.
Default: 0.00037

#### longDelay
The longer delay between pin output state changes.
Default: 0.00101

#### packetDelay
The delay between attempts (packets) of code data transmitted.
Default: 0.01102

Changelog

$3

- transmitCode now returns a Promise and the callback option has been removed
- transmitCode is no longer the exported default, use const { transmitCode } = require('...` instead

$3

- Legacy version
