In this groundbreaking video, we demonstrate how to wirelessly transmit voltage readings up to 150V over a staggering 13-mile (20km) distance using the Heltec WiFi LoRa 32 V3 module and the Meshnology N32 case with a 3000mAh battery and high-gain antenna. This real-world test proves LoRa’s incredible long-range capabilities—perfect for remote monitoring of solar panels, batteries, or industrial sensors without WiFi or cellular networks!
