Long-range RC transmitter “I started using Bluetooth devices like the HC-05 modules, but I found that these sometimes randomly disconnected.

Hello guys, today we are going to setup our 433Mhz transmitter and receiver modules with their supporting cards. We are using cheap 433mhz modules and we are not using any microcontroller with this.

Fig. 2 First implemented PoF-based wireless sensor system: a) Block diagram, b) Experimental setup photograph of the PoF system, Arduino Uno, temperature sensor, and 433-MHz transmitter, (c) ...

It uses an Arduino pro mini to run the show, sending signals to the mpd daemon using a 433 MHz transmitter. Bitlair is pretty large and they often spend time outdoors, so they had to ensure that ...

A low-power 433MHz transmitter is designed using 0.18um CMOS process for battery-less TPMS. It is mainly composed of a PLL frequency synthesizer and a PA, and the transmitter is achieved in a fully ...
