RF modules - transmitter and receiver

RF - modules of model A2111 with a frequency of 315-433 MHz are the basis for creating devices with remote control. When connecting the antenna, the range in a straight section outdoors can reach 200 meters. By supplementing the RF modules with microcontrollers, you can influence the control of any systems, from toys to industrial systems and alarms. Their use for remote measurements, for example, for temperature monitoring at a distance, is no less relevant. Given the prevalence of the frequencies used, it is advisable to control the absence of third-party interference sources.
