Projects using this component
Dot Matrix Clock, Calendar and Weather Station (MAX7219, DS1307)
DS1307 RTC module and DHT22 temperature-humidity sensor is a project that displays real-time data on MAX7219 8x32 dot matrix LED display. The display shows the temperature in Celsius and Fahrenheit, h
ESP32 DHT22 Temperature and Humidity (with LCD Display)
This project measures ambient temperature and humidity using a DHT22 sensor and displays the data in real time on a 16x2 I2C LCD. Data is read from the sensor using the one-wire protocol via the Adafruit DHT library. This project serves as the foundation for IoT weather stations, smart home automation, or environmental monitoring systems in greenhouses. Communication with the DHT22 is established via the ESP32's GPIO 4 pin.
ESP32 Temperature Data Logger (DHT22 + DS1307 RTC + microSD + OLED)
Build a timestamped temperature logger with ESP32! Read DHT22 temperature/humidity every 10 seconds, get real-world time from DS1307 RTC, and log to microSD card as CSV. The OLED displays live temperature (large font), humidity percentage, timestamp, and log counter. The `/temp_log.csv` file on the SD card opens in Excel, Google Sheets, or Python pandas for analysis — perfect for greenhouse monitoring, home/room temperature tracking, laboratory data collection, food storage conditions, or beehiv
