433 MHz Receiver module mini breadboard Optional: 2 wire LCD There are two main libraries used to send and receive data on an Arduino platform: VirtualWire and Manchester code. As Virtualwire is a bit older, no longer supported, and supposedly can only send characters (though there is a way around that) I decided to use Manchester code. 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).

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. Price: $1 to $2 Specifications RF 433MHz Transmitter Frequency Range: 433.92MHz Input Voltage: 3-12V Price: $1 to $2 Where to buy? You can purchase these modules for just a few dollars.

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.

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. IR reciver & RF 433MHz sender with an ATtiny85 for homeautomation I'm using an Digispark ATtiny85 with an micro USB port. IR_RF.ino = Arduino Project You need RCSwitch and IRremote library Install ATtiny support to Arduino: https://digistump.com/wiki/digispark/tutorials/connecting GitHub is where people build software.
Temperature/Humidity sensor DHT11 0.74 $; 433MHz H34A transmitter module 0.73 $; 4xAA battery holder with switch 1$; Total 3.63 $; The receiver used for the tests is an Arduino UNO (only for testing) and a H3V4F receiving module (0.66$) with a cheap arc antenna (0.32$). Sensor-sender schematics. 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.

attiny85 + rf 433 mhz questions - Microcontrollers - Arduino Forum attiny85 + rf 433 mhz questions juanmol August 20, 2013, 9:16am 1 hi!, i need to make wireless an analog sensor. I think i can do it with attiny and a cheap rf kit, it's possible? I mean somethink like that: TX: RX: 2. 433 MHz Transmitter 3. DHT11 4. Attiny85 5. This is the weather stations transmitter. My version sends data from 4 sensors: Temperature, Humidity, Light, PIR. 1. dont mind this bunch of wires, it is just a flatcable that I use 7 wires of: PSU 2 wires LDR 2 wires PIR 3 wires 2. 433 MHz Transmitter 3. DHT11 4. Attiny85 5. This is the weather.
