NodeMCU based Project takes input from a LDR and Logs light intensity into the thinkspeak server.
Collecting data from DHT22 temperature/humidity sensor and LDR luminosity sensor using Adafruit HUZZAH ESP8266 Breakout (NodeMCU 0.9.6)
This project monitors gas concentration, temperature, humidity and light intensity using ESP32. The system provides local alerts using buzzer and LED when gas exceeds a safe limit. All sensor data is uploaded to ThingSpeak cloud for remote monitoring .
DHT11 - измерение температуры и влажности; LDR-module - измерение интенсивности света; cpu, ram, freq - измерение производительности RaspberriPi
