Hello fellow Engineers, something is wrong and I dont know what, just started using a breadboard a week ago for a project. Can anyone help me out?
Please check the components separately. Specially the DHT11 sensor. Check it with an ordinary Arduino and see if you can read it.
Please post schematics and code.
what LoRa module are you using? LoRaWAN or LoRa point-to-point communication? what library? have you tested the module(s) is a separate program as recommended by @aliarifat794 ?
for biometric readings I tend to use a BME280 which works ESP32 and LoRa modules and has a choice of I2C or SPI interfaces
