3 Answers Sorted by: 5 I tried those antennae and I got better range with a whip antenna made from 17cm of copper wire. Probably 1/3 to 1/2 better. Like you I'm combining an ATTiny85 and 433mhz transmitter. The transmitter definitely works better with 12V though it works quite well on 4.5V with good line of sight over about 40m for me.

433mhz Mini Low Power RF Transmitter I got a communication flow transmit/receive working between two Wemos D1 and like to outsource the transmitting part now to a ATtiny85. I used the same code as for the Wemos:

For his project, Erdei assembled five wireless sensors, each with the same hardware, including an ATtiny85 microcontroller, 8-pin DIP IC socket, DHT11 temperature/humidity sensor, H34A 433MHz transmitter module, and a power supply with four AA batteries.

The goal of this small project is to test the radio modules at 433MHz and the ATTiny85, also know as the mini arduino, and avoiding as possible the ArduinoIDE in favor of the PlatformIO (Plugin for atom or Visual Studio Code).

Empfangen und Senden von Daten zwischen ATtiny85 (Arduino IDE 1.06)
Most of that is accomplished in the software but it is helped by the fact that the ATtiny85 normally runs on the 1-MHz internal clock. The rule is that lower clock frequencies require less power and 1-MHz is perfect for the transmitter logic.. You can buy them (get the correct frequency) or you can make your own. At 433-MHz, the right length.

5 SCROLL DOWN TO SEE THE SOLUTION (UPDATE II) ORIGINAL POST: I am currently building a 433MHz remote with two buttons. The remote is controlled by an Attiny85v (8MHz). Sadly it does not work very reliable, sometimes it works other times nothing happens. Here some explanations on what I did and why:

Radio communication 433MHz with ATtiny85 KalmanLabs
Hello, I am trying to interface ATtiny85 with the cheap 433 MHz radio receiver & transmitter pair: The ATtiny is connected to receiver, Arduino UNO is connected to transmitter. The problem is: Arduino transmits the data, but ATtiny isn't responding to it (the led doesn't light up). I tried to use the newest version of VirtualWire library, but ATtiny doesn't have Timer1. The older version of.

The 433 MHz ISM band is used mostly by implanted sensors and thus allows easy integration of such into the BSN. Multiple measurement scenarios have been assessed, including varying antenna orientations, transmission distances and the number of network participants. The mean packet loss rate (PLR) was 0.63% for a single slave, which is.
