Heltec WiFi LoRa 32 (V3) with DHT22 | Long Range Temperature & Humidity Monitoring (OLED Display)

In this project, I demonstrate how to connect a DHT22 temperature and humidity sensor with the Heltec WiFi LoRa 32 (V3) board and transmit data wirelessly using LoRa technology. The transmitted data is received by another Heltec LoRa board and displayed on an OLED screen in real time. This tutorial includes: DHT22 sensor wiring with Heltec ESP32 LoRa LoRa transmitter and receiver setup Sending temperature and humidity data Displaying data on OLED screen This project is ideal for IoT beginners and developers interested in long-range wireless communication. 🔧 Components Used: Heltec WiFi LoRa 32 (V3) (2x) DHT22 Temperature & Humidity Sensor Jumper wires 📌 Buy on Aliexpress: 🔗Heltec LoRa32 V3: https://s.click.aliexpress.com/e/_c3IWTotR 🔗Heltec LoRa32 V3: https://s.click.aliexpress.com/e/_c3C1ulbr 🔗Heltec LoRa32 V3: https://s.click.aliexpress.com/e/_c3T97Ryv 🔗DHT22: https://s.click.aliexpress.com/e/_c3JqTITn 🔗DHT22: https://s.click.aliexpress.com/e/_c3yqVpvR 🔗Heltec LoRa32 V3: https://s.click.aliexpress.com/e/_c4daYsCd 🔗Heltec LoRa32 V3: https://s.click.aliexpress.com/e/_c4KgCuhr 🔗Heltec LoRa32 V4: https://s.click.aliexpress.com/e/_c3EHrPJf 🔗Heltec LoRa32 V4: https://s.click.aliexpress.com/e/_c3TaMGJ3 🔗Heltec LoRa32 V4: https://s.click.aliexpress.com/e/_c3iWk3fX 🔗Heltec LoRa32 V4: https://s.click.aliexpress.com/e/_c2yavHAd 🔗LILYGO® T-Deck Plus: https://s.click.aliexpress.com/e/_c4aQwCrF 🔗LILYGO® T-LoRa Pager: https://s.click.aliexpress.com/e/_c3RHkNwz 📌 Buy on Amazon: 🔗Heltec LoRa32 V3: https://amzn.to/4mwV5FP 🔗Heltec LoRa32 V3: https://amzn.to/4cziZMf 🔗DHT22: https://amzn.to/4tYXbkk 🔗DHT22: https://amzn.to/4tS8ISd 🔗Heltec LoRa32 V3: https://amzn.to/4cvo9bY 🔗Heltec LoRa32 V4: https://amzn.to/41CxpGs 🔗Heltec LoRa32 V4: https://amzn.to/4thwqHS 🔗Heltec LoRa32 V4: https://amzn.to/3Q5SXbZ 🔗LILYGO® T-Deck Plus: https://amzn.to/4mxbkCN 🔗LILYGO® T-LoRa Pager: https://amzn.to/4vP74To 📌 Amazon Finds & Tools We Recommend 🛒 https://c8ke.com/yellowpurple 📥Input the last ESP32 package URL: 🔗https://resource.heltec.cn/download/package_heltec_esp32_index.json 📥 Code & Resources: 🔗https://drive.google.com/file/d/1UiyQVhNIJlspQ6DlXEP2t6rtXZpHgGmM/view?usp=sharing 🔗 More Info & Resources: 🌐 https://meshnology.com/ 📘 https://docs.heltec.org/en/node/esp32/esp32_general_docs/quick_start.html 📡 https://heltec.org/project/wifi-lora-32-v3/ 💬 LIKE | COMMENT | SHARE | SUBSCRIBE 🔥 Please support the channel by subscribing: 🔔 https://www.youtube.com/channel/UCNqYc-ojesF6AbXwiWdZbeg?sub_confirmation=1 #LoRa #dht22 #yellowpurple ━━━━━━━━━━━━━━━━━━ 📺 Watch More DIY & Tech Videos: 🔹 Extend WiFi Range with Another Router (No Cable): https://www.youtube.com/watch?v=_EpCRg5ggEs 🔹 Program ATtiny85 with Arduino Uno: https://www.youtube.com/watch?v=BL1gI4AcMOA 🔹 TP-Link to Netgear Wireless Sharing (WDS Mode): https://www.youtube.com/watch?v=9CS3xfIpK90 🔹 Sokoban Level 11 Solution: https://www.youtube.com/watch?v=xvu6r5_4_T4 🔹 Arduino Ultrasonic Radar System DIY: https://www.youtube.com/watch?v=l8PhAIYB8Us&t=34s 🔹 Connect Two Routers Wirelessly with WDS: https://www.youtube.com/watch?v=X-LLl9OIXK8 🔹 Extend WiFi with Another Router (Easy Guide): https://www.youtube.com/watch?v=wkyKX2ifPFo ━━━━━━━━━━━━━━━━━━ 📩 Contact for Inquiries: 📧 Email: EmailForViewers@gmail.com ━━━━━━━━━━━━━━━━━━ 🌟 Thank you for your support! 🌟
