DIY Wireless Temp Sensor | ESP32 + LoRa | 1 Mile Range, Off-Grid, Free! NyBot 2025-04-19 | In this video we learn how to use Wi-Fi LoRa 32 V3 from Meshnology. I'm going to explain the module and specs, show how to install library for Arduino, we learn how to send transmit Text over LoRa, then we learn how use the OLED display, then we use DHT22, measure temperature and transmit it over the air for free to more than 0.9 miles*** Documentation and Resources *** Visit Meshnology website meshnology.comHeltec Documentation: docs.heltec.org/en/node/esp32/esp32_general_docs/quick_start.htmlDownload Arduino code for this video: robojax.com/RJT387**** Purchase WiFi LoRa 32 V3 from Affiliated stores ****Amazon USA: amzn.to/4jlAzoGAmazon USA (N30 Shell): amzn.to/44ivKbpPurchase from Meshnology.com meshnology.comAmazon Canada: amzn.to/4i8vWNLAmazon (Europe) : amzn.to/3Ga9CpuRelated videos:LoRa Cube Cell : youtu.be/-dUKnIXPMeAUse Chapters from timeline or click on the time00:00 Start3:54 Specs8:25 Documentation page9:52 Package and battery13:07 Powering it up for the first time16:34 Installing Library17:27 Transmitter Basic code18:57 Receiver Basic Code19:43 Demonstration of sending receiving text22:12 OLED demo code23:01 Basic Text on OLED display code24:50 Basic Text on OLED demo25:22 Reading temperature with DHT2227:12 LoRa Transmitter Temperature and Display28:33 LoRa Receiver Temperature and Display30:29 Triggering LED when temperature increases31:44 LoRa Transmission Range Test33:20 dBm and Milli WattGet other projects code: http://nybot.cc#nybot #LoRa #meshnology
