MySondy GO is a project to facilitate the search for Radiosondes in the field. Using a TTGO ESP 32 (433 Mhz) module and a simple smartphone, it is possible to receive the radio signal directly from the probe. The geographical position of the probe is displayed on a map using the smartphone in Bluetooth connection with the module. The main advantage of the system is that you don’t need a laptop. The TTGO module fits in a matchbox. The author of the system is Mirko Dalmonte, IZ4PNN. The development board called TTGO is equipped with an Esp32 microcontroller well known by the « Makers » and a SX1276 or SX1278 modem. More info : hamprojects.wordpress.com 73 Anthony KF4GOH
