UCTRONICS Complete ESP32 Indoor Air Quality IAQ Kit for Arduino IDE with ESP32 Development Board 0.96” OLED Display IAQ TVOC Sensor Module DHT11 Temperature and Humidity Sensor

Description of product

  • The UCTRONICS ESP32 Indoor Air Quality IAQ Kit includes ESP32 development board, 0.96” OLED display, DHT11 temperature and humidity sensor, IAQ TVOC sensor as well as the UCTRONICS user guide (link for download)
  • This ESP32 development board has a 32bit dual core 240MHz processor, support WIFI and BLE4.2 connection, and fully support Arduino programming IDE
  • The IAQ TVOC sensor module is used to detect the indoor air quality. It can measure TVOC levels and provide TVOC equivalent predictions. This sensor support serial communication and you can read the data via UART
  • The 0.96" 128x64 pixel OLED display supports SPI and I2C, wide view angle, low power consumption and high response speed
  • You can use this kit to measuring three parameters that determine the quality of the indoor air: Temperature in degree Celsius, Humidity in Percentage, Total Volatile Organic Compound (TVOC) in Parts per Million ppm
