Wireless communication between two Arduinos using inexpensive RF modules
https://www.electronics-lab.com/wireless-communication-between-two-arduinos-using-inexpensive-rf-modules/
Raj from Embedded Lab has posted a new article exploring an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules. He used a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless temperature and humidity monitor.

Vlad @ denialmedia.ca has build a solar powered weather station based on ATMega328 microcontroller that is able to measure temperature, a humidity, and UV radiation and it uploads measurement on WeatherUnderground network. The data are send to the air using a 433MHz link. The sensors used are DHT22, ML8511, BMP180 and a TP4056 charger IC is used to […]

by simpletronic @ instructables.com This is a multi-chapter instructable. I will be describing the making of a short/medium range RF remote-control using the UHF 433Mhz frequency. It´s impossible to setup & adjust a RF transmit-receive link if you are not sure the transmitter is working properly.At 433MHz, your multimeter or even a regular oscilloscope are […]
