Current package documentation

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

npm install 433MHz

Usage

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,
});

Options

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

Version 2.0.0

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

Version 1.1.0

  • Legacy version
