Électronique en amateur Communication RF 433 MHz entre ATTiny85 et Arduino
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.

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.

LoRa is similar to Bluetooth and WiFi in that it operates in a frequency band allocated to industrial, scientific, and medical (ISM) applications (read more about frequency allocations at this FCC link).The LoRa ISM band permitted in the U.S. is the 902-928 MHz band, while Bluetooth and WiFi operate in the 2400-2483.5 MHz and 5725-5850 MHz (5G WiFi) bands (more on the history of permitted.

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.

These modules benefit from the addition of an antenna, which ideally is a length of wire an even fraction-0.5 or .25-of the wavelength. The frequency wavelength of 433Mhz is 69.28 centimeters. A quarter of that is 17.32 cm. The antenna should be soldered to the pad next to small coil on the receiver board. (On most boards, the pad is.

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.

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:
