Electrical Engineering Undergraduate Thesis. Designing a Real-Time IoT LoRa Based System Using DHT11 and Dragino LoRa Shield To Determine Radio Refractivity, Refractivity Gradient, and effective earth radius factor (k-factor)
The channels shows the measured values from a IoT-Node. Every time the Node wakes up, it reads the values out and send them to a raspberry pi over LORA radio interface. In the next step the MQTT client transmit the data to the ThingSpeak platform.
Sistema de monitoramendo do nível de gás, temperatura e umidade. Dados são capturados por dispositivo ESP32 Lora "sender" e transmitidos ponto-a-ponto ao Lora "receiver". Este se comunica com a Internet e registra os dados no ThingSpeak.
LoRa exercise. Old-school TSL230R light->frequency sensor / Whispernode LoRa node / Heltec ESP32 LoRa base. Using the LowPower library and powering down the TSL320 between readings. Two AAA batteries. Reports outdoor light levels every 30 minutes.
