To interface a dht sensor with a microcontroller to send real-time temp. and humidity data to the thinkspeak cloud platform for online monitoring and data analysis
This channel monitors and logs real-time freezer temperature using a DS18B20 sensor and ESP32. Safety levels are indicated using LEDs and data is sent every second via MQTT.
This channel measures temperature and humidity using a DHT11 sensor connected to NodeMcu.
LoRaWAN-based IoT project for real-time environmental data collection including temperature, humidity, motion, and battery status. Data is sent via TTN and visualized on ThingSpeak
